Introduction
Overview
•
Multiple Working Viewports: You can show one, two, or four Viewports
simultaneously. Each Viewport can reference a separate camera, model
set, and environment.
•
Baked environmental lighting per part. Fast too.
•
Global Illumination dramatically improves the realism of objects in raster
views, so as to provide near-raytrace quality in near real-time.
•
Models can reflect other models in raster mode.
•
Several rendering modes:
– Preview : Quick shots of your scene using your configured cameras.
– Accurate: Full power raytracing with enhanced iRay Photoreal 2014,
or Stellar (your choice), for superior results (but slower and quite
noisy for real-time editing).
•
Can scale seamlessly to one or more workstations or to a large cluster.
•
Works with a wide variety of CAD data.
•
Significantly accelerated with the powerful parallel processing power of
NVIDIA CUDA-enabled GPU's. More CUDA cores gives better
performance.
•
Auto-update of backplates and HDR environment images. When you edit
a backplate or HDR image in PhotoShop, HDR Light Studio, Filter Forge,
or similar software, the image is automatically updated in your Bunkspeed
project.
•
In Full Screen Mode (F11), borders and tabs disappear, providing a clean
view of your scene for presentations and daily use.
•
Ability to merge BIF files by dragging and dropping into the scene.
•
Ability to move a part to a new group without changing the part’s position.
•
Ability to copy-and-paste settings between environment images.
•
Numerous supported import formats:
– AliasStudio 2012 and prior (.wire)
– 3D PDF

How It Works
Bunkspeed DriveSuite is a fully raytraced rendering environment, by default.
(By changing rendering modes, you can use fast raytracing, or disable
raytracing entirely, to speed up editing on lower power hardware — and then
enable full raytracing as a final step.) The software is constantly updating the
scene using raytracing by taking full advantages of all available CPUs and
CUDA GPUs.
Unlike traditional 3D applications, you do not need to guess and check before
generating final results. In Bunkspeed DriveSuite, you interact with the final
result at all times, even while animating.
A Bunkspeed DriveSuite project consists of an environment sphere that
includes a transparent ground plane for accurate shadowing, and an HDR
environment image that maps to the spherical environment. No further lighting
setup is required, although additional sources of light are available.

will show your project in real-time.
For details on models, see "Chapter 4: Working with 3D Models” on
page 66.
Use the Camera
You can move the current camera relative to the look-at point. You can of
course change the look-at point too. (The look-at point is the point in 3D
space where the camera focuses, rotates around, and zooms towards.)
4. To move the camera, HOLD the ALT-KEY and use the mouse as follows:
– Rotate: LEFT-CLICK-HOLD inside the Viewport and DRAG the
MOUSE to orbit the camera around the focal point.
– Pan: MIDDLE-CLICK-HOLD inside the Viewport and DRAG the
MOUSE to move the camera and focal point together.
– Zoom: RIGHT-CLICK-HOLD inside the Viewport and DRAG the
MOUSE to zoom the camera in / out, relative to the focal point.
– Perspective: ROTATE the MOUSE WHEEL to dolly and change the
focal length of the virtual lens.
– Look-At: Or hold both the CONTROL and ALT-KEYS, and RIGHTCLICK on a new look-at point in the 3D Viewport.
Library Tab
For details on cameras, see “The Camera” on page 57.
Assign and Edit Materials
In Bunkspeed DriveSuite, a “material” is a scientifically accurate simulation of
a substance such as polished aluminum, glossy paint, glass, emerald, wood,
rubber, etc. By mapping materials on models, the models assume an uncanny
realism.
Each “type” of material in Bunkspeed DriveSuite is defined by a unique set of
parameters, including up to four textures (color, specular, alpha, bump).
Different materials of the same type have the same parameters with different
values. Bunkspeed DriveSuite comes with a variety of materials. You can
create new materials by modifying the parameters of existing materials, and
by importing materials created by others. For details on materials, see
"Chapter 5: Working with Materials” on page 82.
Here’s how you map a material onto a part in a model:
5. In the Palette, select the Library Tab to activate Library Mode.
6. To display the Material Library, select Materials in the drop-down menu
near the top of the Library Tab. The Materials Library contains all the
materials (in BMF format that can be shared and emailed) in the
Bunkspeed Content \ Materials folder, by default. Notes:
– You can obtain materials from the Bunkspeed web library. For
instructions, see “Web Libraries” on page 55.
– Materials can also be created via the right-click menu in the material
tab of the Palette.

Getting Started in Standard Mode
7. DRAG-AND-DROP any material from the Materials Library to the target
part in the model in the 3D Viewport. This action accomplishes two things:
– The material is mapped to the target part.
– The material is added to the current project, and will be packaged and
saved with the current project – making the material independent of
your Material Library.
Do not confuse the Materials Library in the Library Tab with the Materials Tab:
•
The Materials Library is accessible via the Library Tab of the Palette. The
Materials Library contains all the material files in the Bunkspeed Content \
Materials folder, by default – regardless of whether or not these materials
are used in the open project.
– The materials in the Material Library are independent of specific
projects, making the entire Material Library available to all projects.
– You cannot directly edit a material in the Material Library. But you can
bring a material from the Material Library into the open project, and
then edit the material with the parameters in the Material Tab, and
save the modified material as a new material in the Material Library.
–
DriveSuite saves materials in BMF format in the Bunkspeed Content
\ Materials folder, by default. You can copy, share, and even email
BMF files to other DriveSuite users.
•
The Materials Tab of the Palette contains only the materials that have
been added to the open project.
– Note: In the Materials Tab, LEFT-CLICK any material to display its
parameters. You can optionally edit these parameters to modify the
material. Your edits will effect instances of the material on parts in the
open project, but will not affect the Material Library.
Import an HDR Environment Image
High dynamic range images (HDR) can contain a far greater contrast range
and color depth than regular 2D images. HDR images accomplish this by
using special formats, such as HDR and EXR, that describe RGB colors with
32-bits per channel of data. That’s a lot more color and luminance information
than standard 2D images using 8-bits per channel.
Bunkspeed DriveSuite lets you load an HDR image onto an environmental
sphere that contains your entire scene. The HDR image will then radiate light
into your scene from all directions, according to the RGB values of individual
pixels in the HDR image. Here’s how:
8. To display the Environments Library, LEFT-CLICK the Library Tab in the
Palette, and then select Environments in the drop-down menu therein.
The Environments Library contains all the HDR images in the Bunkspeed
Content \ Environments folder, by default.
9. In the Environments Library, DRAG-AND-DROP any HDR image into the
3D Viewport. This action applies the HDR image to the environment
sphere containing the open project, causing the HDR image to provide
the light in your scene.
– Alternative: Double-click the environment icon in the Environment
Library to load it into the environment of the open scene.

Bunkspeed Tutorial
–
Getting Started in Standard Mode
Alternative: New HDR environment images can also be loaded via
the right-click menu in the Scene tab of the Palette.
10. You can tune an HDR image in Scenes Mode, as follows:
– To activate Scenes Mode, LEFT-CLICK the Scenes Tab tab in the
Palette (see the figure to the left). All environments that have been
loaded into the open project are listed in the Scenes Tab of the
Palette.
– In the Scenes Tab, LEFT-CLICK the target environment image in the
Environments Tree near the top, and adjust the Brightness
parameter to change the total amount of light the environment image
radiates into your scene.
– Adjust the Gamma parameter to indirectly change the contrast of the
environment image.
– Experiment with changing other parameters in the Scenes Tab.
•
Here’s another way to apply a different environment image to the open
scene:
i. Activate the Scenes Tab in the Palette.
ii. In the Scenes Tab, double-click the icon of the environment you wish
to load into the open scene.
For details on environments, see “Working with Scenes”.
Import a Backplate Image
A backplate is a standard 2D image that provides a background for your
scene, without affecting the lighting in the scene. By design, backplates do
not emit light into the scene, and do not receive shadows. Also, backplates
always remain in the center of the 3D Viewport, orthogonal to the camera,
regardless of where you move the camera.
You can use a variety of 2D image formats, such as JPEG, as backplate
images.
11. To display the Plates Library, LEFT-CLICK the Library Tab in the Palette,
and select Plates in the drop-down menu. The Plates Library contains the
backplate images in the Bunkspeed Content \ Plates folder, by default.
12. From the Plates Library, DRAG-AND-DROP any image therein into the
3D Viewport – placing the image in the background of your project. After
loading a backplate image into the open project, the image will be listed in
the Scenes Tab of the Palette.
– Alternative: New backplates can also be loaded via the right-click
menu in the Scene tab of the Palette.
For details on backplates, see "Chapter 6: Working with Scenes” on
page 88.

Auto-Size Options: Lets you set the rules for the size objects should be
scaled to when they are “auto-sized” upon import.
– Minimum Size Limit: Sets the smallest that a part should be if it
initially imports far too large.
– Maximum Size Limit: Sets the largest that a part should be it initially
imports far too small.
– Scale Using Powers-Of-Ten: Applies a power of ten multiplier to
either increase or decrease the size of the original model when it is
auto-sized.
•
Auto-Paint Options: When enabled, Autopaint builds an association
between the names you give parts/materials/layers in your CAD package,
and the names of Bunkspeed Drive Suite materials you assign to those
parts after import. Based on your paint/naming pattern, Drive Suite learns
how to Autopaint a model upon import. (Example: Suppose in CAD you
always name a tire layer “Tires,” and in Bunkspeed Drive Suite you
always paint the part called “Tires” with the Black Rubber material. As a
result, every time you import a model that has a part called “Tires,” Drive
Suite will automatically assign the Black Rubber material to that part. This
feature essentially lets you pre-paint your model in the CAD package, so
you don't have to assign materials once that file is imported.)
– Enable Auto-Paint by Default: Activates the auto-paint feature each
time the program is run.
– Enable Auto-Paint Data Storage: Activates a persistent list of the
associations you make during usage.
– Maximum Auto-Paint Storage: Lets you determine how big the Data
Storage list can get.
– Reset Auto-Paint Data: Clears your Data Storage list and lets you
start over.

Quality Options:
– Anti-Aliasing Level controls the process of softening the unnaturally
precise or stepped edges (sometimes known as ‘the jaggies’) that are
created when a computer-generated object is placed against a
contrasting background. This softening process is accomplished by
using pixels of intermediate shades as a buffer between the object
and its background. The higher the value of Anti-Aliasing Level, the
better the step removal, but the more impact the performance. The
available settings will vary based on your video card.

Maximum Texture Resolution: Lets you select the maximum texture
resolution. The default is 4096x4096 pixels. The following options are
available:
» 2048x2048 (DirectX8 maximum)
» 4096x4096 (DirectX9 maximum)
» 8192x8192 (DirectX10 maximum)
» 16384x16384 (DirectX11 maximum)
Shadow Quality determines the smoothness of the ground shadow
and self-shadows.
Shadow Resolution determines the pixel dimensions for the map
created for the shadow projections.
Environment Resolution determines the pixel dimensions used to
clamp the HDR environment image.
Gloss Resolution determines the pixel dimensions that the reflection
map is calculated at, so as to determine the material gloss levels.
Limit Rough Reflection Maps: When enabled, the roughness of
materials is classified into four gloss levels using a faster but less
accurate technique. When disabled, the actual roughness of
materials is calculated with a slower but more accurate process.
•
Supersampling Accumulation Options: Accumulation is a
supersampling process that anti-aliases the scene, conveys accurate
environment-based lighting and shadows, and adds subtle depth-of-field
to the scene. (Note: Enable Depth-of-Field in the Cameras Palette before
using the Accumulation feature.)
– Enable Automatic Supersampling: When enabled, accumulation
starts in the loaded scene when you press F10, and continues to
improve the scene over time. When you do anything in the Viewport,
such as move the camera, accumulation pauses.
– Auto Supersample Delay Time: Sets the time before accumulation
begins, after which you pause real-time work.
•
Performance Options:
– Enable Performance Mode: Activates a drawing mode wherein all
shaders are simplified significantly, so as to dramatically increase the
speed of realtime editing. It is useful for models that are very large or
have lots of textures – and for ensuring animations play back
consistently at 30 FPS. Even if this mode is enabled, the final image
will still be rendered with the original shaders.

VIEWPORTS
A Viewport dominates most of the area in the Bunkspeed DriveSuite window.
Bunkspeed DriveSuite provides you with a 3D Viewport, plus additional tabs
that appear when you open images in the Image Viewport, as explained
below.
3D Viewport
The 3D Viewport shows the open project with the currently selected camera.
When you move the camera around the scene, or change any content, the 3D
Viewport updates in real-time.
Image Viewport
The Image Viewport displays the images in the Image Library. Since
screenshots and renders are saved to the Images Library by default, the
Image Viewport is a convenient way to look over your output images.
Rendering Viewport
The Rendering Viewport displays the currently rendering image, when
applicable.
Login System
Bunkspeed DriveSuite provides a convenient means for you to download
content for use in your projects. By copying shared content from Bunkspeed's
servers to your local hard drive, you can quickly build a vast local library of
materials, HDR environment images, models, backplate images, and more!

Toolbars
TOOLBARS
The Main Toolbar provides selectors for most tools other than the camera.
The Camera Toolbar / Panel provides controls for the current camera.
Main Toolbar
The Toolbar appears near the top of the 3D Viewport, by default. The Toolbar
provides you with shortcuts to some of all of the following functionality
depending on which version of software you have.
CONFIGURATION TOOLS
As you edit a scene, the cumulative cause-and-effect result of your actions is
of course what you see evolving on your screen. Your edits are part of the
configuration you were in when you made them. When you first create a new
project, the base configuration is automatically selected, so all your edits are
part of the base configuration.
When you create a new configuration, or select any existing configuration
other than the base, then you are creating a new branch to store your
subsequent edits. For example, if you create a new configuration called
“Config1,” and then change the dominant color of your model, the change is
applied in Config1 only. While you remain in Config1, the change in color is
clearly visible. But if you then switch back to the base configuration, then you
will see your model in its previous color prior to creating Config1. In short,
actions you take while in one configuration do not affect the edit history of
other configurations – with the exception of the base configuration itself. Edits
you make while in the base configuration affect all other configurations.
The primary use of creating new configurations is to provide slightly different
versions of a base scene. For example, while in the base configuration, you
could create and finish a scene containing a yellow car model lit by an HDR
image taken in a specific dealer showroom. Then you could create a new
configuration called “Red Car,” and paint the car red. Then create a “Black
Car” configuration and paint the car black. You could then switch between
yellow, red, and black cars simply by switching configurations.
The following Configuration Tools shows you which configuration you’re
currently working in, and provides quick means to switch configurations:

Context-Sensitive Configuration Menu
Almost everything in Drive can be put into Configurations. Here’s what you
can do with them in the context-sensitive menu:
•
In the Materials Tab of the Palette, if you right-click a material that’s used
in a model. Then in the context-sensitive menu:
– select Set (Material) in Configuration > Set in New Configuration
to create a new Configuration and add the selected material to it;
– or select an existing custom Configuration from the list.
•
You can now lock a Configuration in the floating Palette / Toolbar. When
used for HDR images and backplates, the word “Material” doesn’t appear.
•
Can now click Edit in the floating Toolbar, and then Duplicate an existing
Configuration. You are then free to experiment with that configuration
while preserving the original.
RENDER SELECTION
The Render Selection button in the Main Toolbar (see figure to left) lets you
select from the following real-time rendering modes:
•
Preview: A realtime approximation of raytraced lighting.
•
Accurate: Top quality rendering using new iRay and Stellar raytracing
technology. Takes longer of course.
•
Blended: When in Accurate rendering mode, enabling Blended causes
the scene to automatically switch to Preview Mode whenever you do
anything – such as moving the camera, moving the model, playing an
animation, dragging a material, and even just clicking the mouse in the
Viewport. As soon as you stop clicking or moving the mouse, the scene
starts to accumulate raytraced lighting again.
TURNTABLE
You can add a real-time turntable to the selected model, as follows:
1. Select the Turntable tool from the Main Toolbar.
2. To create a turntable for the selected model, click the On button on the left
of the Turntable drop-down (see figure). Then control the turntable with
the other controls in the drop-down, from left to right:
– Play / Pause: Starts and stops the turntable.
– Slower: Causes the turntable to spin slower (Ctrl-,)
– Faster: Causes the turntable to spin faster (Ctrl-.)
– Reverse Rotation: Causes the turntable to reverse directions 

OBJECT MANIPULATION TOOLS
Brings up the Transform Manipulator to visually Move, Scale, or Pivot (i.e.
rotating) the selected model or material, as illustrated below.
Move
•
If the Selector Tool is in Model Mode: Activating the Move Transform Tool
displays the Transform Manipulator for visually Transforming Models, as
well as the Model Tab for numerically transforming models. (By
“transforming” we mean moving in 3D, as well as rotating around all 3
axes.) Note:
– Right-clicking and dragging the center yellow square of the Move
manipulator “sticks” the selected object onto any other object you
drag it over. This feature is useful for placing object on a table for
instance. It uses the selected objects’ pivot point as its “base,” so
moving the pivot to the bottom of the bounding box is recommended.
•
If the Selector Tool is in Material Mode: Activating the Move Transform
Tool displays the Texture Manipulator for visually Mapping Textures onto
parts in models, as well as the Material Tab for numerically mapping
textures.
Scale
The Scale Transform Tool works the same as the Move Transform Tool

are hidden.)
•
Disabled: When enabled, the selected model or part no longer affects
lighting, but it does remain visible.
•
Faded: Hides a model from the camera’s view, but leaves it in the scene
in terms of lighting.
•
Corner Radius: Adds a visual fillet or radius to parts with hard edges for
visualization purposes. The edge then produces a more realistic highlight
without requiring a modeled radius.

•
Part/Normals Control: Edits and rebuild the normal vectors on the
selected part. For details, see “Part/Normals Control” on page 78.
•
Transform: Provides parameters for numerically translating, rotating,
scaling, and pivoting the selected model or part:
– Position XYZ: Translates the selected item in 3D space.
– Rotation XYZ: Rotates the selected item in 3D space.
– Scale XYZ: Scales the selected item by axis in 3D space.
– Scale All: Scales the selected item proportionally in 3D space.
– Reset: resets the model and all its parts to its original coordinates.
– Freeze: leaves the model in place, and sets all transform values to
neutral (i.e. Position = 0,0,0 and Size = 1.0 etc)
– Pivot XYZ: Translates the pivot point of the selected item.
– Pivot Rotation: Rotates the pivot point of the selected item.
– Reset: resets the pivot to its original coordinates.
•
Follow: Causes the camera to follow the model you select in the dropdown menu.
•
Physics: These parameters determine how the selected model reacts to
gravity and collisions in the scene.
– Physics Type:
» None disables physics entirely for the selected model.
» Static locks the selected model in its current location, while
allowing other models with dynamic physics to collide with it.
» Dynamic lets the model react to gravity and collisions with
accurate simulation of motion and dynamic impact. Dynamic
physics can be recorded, then combined and played back with
other animations. The Mass parameter defines the dynamic mass
of the selected model.
» Car activates full dynamic physics for vehicle models.

Vehicle Setup: These parameters help you make an imported vehicle
driveable:
– Vehicle Facing: select the direction (i.e. axis) the front of the vehicle
is facing from the drop-down list.
– Create Wheels from Selected Parts: After first selecting all the
rotating parts in the wheels of your vehicle, click this button to
enabled those wheels to spin and rotate when driving. (NOTE:
Calipers do not rotate, so don’t select them.)
– Create Calipers from Selected Parts: After first selecting all the
parts in the brake calipers of your vehicle, click this button to enabled
those calipers to rotate with the wheels as you turn them.
•
Rasterization Options:
– Enable Ground Shadows: Toggles ground shadows that are
generated in realtime from the HDR environment image. You can
control the intensity of the shadows via the Environment Shadow
Intensity slider in the Scene Tab of the Palette.
– Show Wireframe: Toggles visibility of the tessellated polygons in the
selected part or model.
– Reflect Other Models: When enabled, the selected model reflects
other models in the scene, with some impact to performance.
– Reflect in Other Models: When enabled, the selected model is
reflected in all other models in the scene. This feature complements
the Reflect Other Models feature (above).
– Visibility: Controls the directional culling (i.e. selective removal from
rendering) of one side (front or back) of the selected part mesh. The
default of “All” culls nothing. “Clockwise” usually culls the backside of
the mesh, and “Counter Clockwise” usually culls the front side,
depending on how the normals are aligned in the part.
•
Baked Lighting: While in real-time raster mode, you can still see most
objects with high quality lighting baked in. Simply select the part(s) you
want to be realistically lit with the Parts Tool, and select either Vertex or
Texture Lighting to bake raytraced lighting into the selected parts:
– Enable Baked Lighting: Toggles the visibility of baked lighting
without removing it from the selected parts.
– Vertex Lighting calculates global illumination and applies the results
to each vertex in the selected part(s). This technique works very well
for high-polygon models, but it can take some time. Options:
» Accurate: Uses the color, intensity, and direction of light from the
HDR environmental image for very accurate results.
» Approximate: Reduces the loaded HDR to non-directional light
and calculates baked lighting based on the occlusion of other
parts and objects in the scene.

Texture Lighting calculates global illumination and applies the
results to a texture, which is then mapped onto the selected parts.
This technique works well for low-polygon models, but does not
exploit the polygonal detail in high-poly models. Options:
» Low / Normal / High: “Low” generates a baked texture of 64x64
pixel resolution. “Medium” generates a texture of 256x256. “High”
generates a texture of 1024x1024.
» Accurate / Approximate: “Accurate” uses a more accurate but
slower algorithm. “Approximate” uses a faster but less accurate
algorithm.
Approximate Shadow Intensity: If you select “Approximate” from
the calculation options above, then you can control the intensity of
generated shadows here.
Remove Baked Lighting: Clears baked lighting from selected parts.
•
Tessellation: Select the part you want to re-tessellate, choose the new
tessellation value in this “Tessellation” section of the Model Palette, and
click the Re-Tessellate button to re-tessellate the selected part. NOTES:
– The “Tessellation” section of the Model Palette is available only when
you select a part in a model that was imported from geometry that
needed to be tessellated (e.g. .wire, .sldprt, .sldasm, .3dm, .asm,
etc.). If you select a part that was in a model imported from pretessellated geometry, such as .obj, then the Tessellation section will
not be available.
– You can re-tessellate a part only if the original model (prior to import)
is still in the same relative location to the Bunkspeed project file.

Material Tab
The Material Tab of the Palette provides you with the options discussed in this
section. When you select a material on a model, the material is highlighted in
orange.
MATERIAL TREE
Each and every material in the open project is listed in the Material Tree near
the top of the Material Tab. Display options: tiles, thumbnails, or text lists.
1. To select a material and display its parameters, LEFT-CLICK its name or
icon in the Material Tree (see image to the left).
2. To apply a material to part in a model in the 3D Viewport, DRAG-ANDDROP the material from the Material Tree to the target part.
MATERIAL PARAMETERS
When you select a specific material in the Material Tree (or select a material
on a part in a model), the parameters defining the material appear in the
Material Tab of the Palette. Exactly which parameters appear and depends on
the type of the selected material (e.g. glass, metal, leather, etc). Different
parameter values for the same type of material produce variations within the
type (e.g. silver verses gold).
You cannot create new types of materials, but you can edit the values of
material parameters to create unique variations within each type.
All materials in Bunkspeed DriveSuite share the following parameters:
•
Material Name: An arbitrary name for the material. You can optionally
overwrite the default name.
•
Material Type: The type (i.e. category) of material – such as glass,
metallic paint and plastic. Different types of materials have different
parameters that appear here. For a list of all types of materials supported
by Bunkspeed DriveSuite, with details on the parameters for each type,
see “Types of Materials in Bunkspeed DriveSuite” on page VII.
•
Color: The base color of the material. Usually white.
Texture Parameters
Expanding the Texture parameters near the bottom of the Material Tab allows
you to add Color, Specular, Alpha, and Bump textures to the selected
material. (For usage instructions, see Add and Edit Texture Materials.)
After you load a texture for a material, you can tune its parameters. When you
apply a material with one or more textures to an object, Bunkspeed
DriveSuite maps the textures onto the selected parts in the target object.
Copyright © Bunkspeed, Inc. 2002-2014
•
Sync Textures: Once you fill in the values for one type of mapping, select
this option to copy those values to the other types of mapping (assuming
the other types have loaded textures).
•
Color, Specular, Alpha, or Bump: Allows you to load a texture of the
selected type: Color, Specular, Alpha, or Bump. (This option appears only
if you have not already loaded a texture of this type.)

The following parameters appear after you load a color, specular, alpha, or
bump texture to the selected material:
Copyright © Bunkspeed, Inc. 2002-2014
•
Enable Texture: Turns on/off the texture that has already been loaded.
(This option appears only if a texture of the selected type has already
been loaded.)
•
Blend Texture: (Color and Specular textures only) Combines the loaded
image with the color of the material itself in an additive fashion that allows
you to tint textures.
•
Brightness: Changes the reflectivity of the loaded specular map itself.
•
Tile (U, V): The default of (1, 1) causes exactly one copy of the texture to
be mapped, from edge to edge, across each target part. Values greater
than “1” cause tiles of the texture to repeat across each part. For
example, a value of (2, 2) causes the texture to repeat twice along each
axis, forming a 2x2 grid of tiles across the surface of each host part.
•
Shift (U, V): Offsets the center of the texture in horizontal (U) and vertical
(V) directions, relative to the normalized texture coordinates on the host
part. The default of (0,0) centers the texture on the part.
•
Repeat (U, V): Toggles between single and multiple copies of the texture.
per axis.
•
Rotation: Rotates the texture in texture space on the target surface.
•
Bump Scale: (Bump textures only) Determines the height of the bumps.
Negative values give the impression of engraving.
•
Invert Bump: (Bump textures only) When inverted, hills in the bump
texture become valleys, and valleys become hills.
•
Treat as Normal Map: (Bump textures only) When you first add a bump
or normal texture, DriveSuite makes an educated guess about which
type it is (indicated by the half-checked box for this parameter). When
using actual normal maps, you can manually select Normal Maps by fully
checking this box. Otherwise, use Treat as Normal Map to toggle between
Bump Mapping and Normal Mapping, and select whichever produces the
best results.
•
Treat Bumps as Displacement: Converts the highlights and shadows in
the greyscale bump texture to actual 3D displacement. This adds realism
by adding actual physical depth to the bump texture!
– Technical Note: When making the conversion from 2D to 3D, the
application re-tessellates the underlying geometry to add 2 triangles
to every pixel on the texture mapped to that geometry. For high detail
textures, you will need a lot of RAM or vRAM.
•
Remove Texture: Removes the texture of the selected type (i.e. if
Specular is selected, this button removes the Specular texture.
•
Load New Texture: Loads another texture of your choosing.
•
Save Texture As: Saves the texture to disc.

Importing Models
Working with 3D Models
You can load multiple 3D models into your Bunkspeed DriveSuite project. (In
this document, models, objects, and meshes are all the same thing: 3D
geometry that’s defined in a computer file.) Coordinates within a model are in
model space (i.e. relative the model’s origin), and coordinates in a Bunkspeed
DriveSuite project are in project space (i.e. relative to origin in the center of
the scene). The separation of model space and project space helps
Bunkspeed DriveSuite preserve the correct relative sizes of multiple models
in the same Bunkspeed DriveSuite project.
IMPORTING MODELS
Bunkspeed DriveSuite can import 3D models in many common file formats.
Most 3D modeling software today can export to at least one of the formats
that Bunkspeed DriveSuite can import. (For a complete list of supported
import formats, see “Import Formats for 3D Models”.) Support for some of
these 3D formats depends on plugins that you can download for free from
Bunkspeed’s web site:
http://www.bunkspeed.com
Importing a model is easy:
1. To import a model, select File > Import from the Main Menu. The Import
Settings dialog appears, so you can locate and load a model.
– Alternative: Select Project > Import Model from the Main Menu.
– Alternative: In the Model Tab of the Palette, RIGHT-CLICK in the
Model Tree, and select Import from the Context Sensitive menu.
2. The Import Settings dialog (below) may contain format-specific import
options. If the dialog appears, select the import options you prefer and
LEFT-CLICK OK to import the model:
– Geometry:
» Apply Auto-Size: If enabled, the importer automatically sizes the
model to best fit within the open scene.
» Part Grouping: Groups geometry into parts based on your
choice of layers, materials, and/or divisions in the source model.
The Automatic option (generally recommended) uses all three to
produce the most diverse groupings. The Flatten option ignores
groupings and imports the geometry as a single part.
» Tessellation Quality: Determines the relative accuracy of the
results when converting a model to polygons. The higher the
tessellation quality, the more polygons are used to represent
curved surfaces in the model, and the smoother the results. The
downside to high quality tessellation is a heavy model with a
large file size that’s more taxing on your hardware.

Advanced Tessellation Settings: Lets you fine-tune exactly
how models get tessellated (i.e. converted into polygons).
Experts only.
» Advanced Sewing Settings: Specifying multiple passes ensures
that parts in models are all connected (i.e. they all share vertices),
so as to eliminate seams between adjacent materials.
» Design Program Settings: Lets you set the alignment (Vertical
Axis and Horizontal Axis) and the units of the Importer to match
how the model is set up in the source software.
Materials: To ignore materials, uncheck the Import Materials option
on the tab itself. To import materials, check that option and configure
the following import parameters:
» Ignore Texture References: ignore all textures associated with
materials in the source model.
» Auto Search for Missing Textures: look in logical places for
missing textures referenced by materials in the source model.
» Texture Auto-Search Paths: Lets you specify where DriveSuite
looks for textures referenced by materials in the source model.
Cameras: By default, all cameras in the source file will be imported, if
possible. To ignore cameras, uncheck the Import Cameras option.
Importing OBJ Files
When exporting the OBJ file from your source software, make sure to choose
a tessellation that meets your needs. Close-ups in Bunkspeed DriveSuite
look best at higher tessellation (i.e. more triangles for smoother surfaces) than
more distant views. You must determine tessellation inside the 3D modeling
software you are using to create the model. You can’t change the tessellation
of a model after it’s been imported into Bunkspeed DriveSuite.
Fine tessellation increases the size of an OBJ file, so ensure that your
computer has enough RAM and other resources to handle your preferred
degree of tessellation.
The OBJ file format does not support a full scene graph, but it does maintain
all material assignments, including textures. When importing an OBJ file and
its material files, make sure that all associated files stay together in the same
folder. Upon import of the OBJ file, Bunkspeed DriveSuite will automatically
copy the model’s textures into the Textures Library.
All materials inside the OBJ file are converted to material groupings in
Bunkspeed DriveSuite. Specifically, all parts in your model sharing the same
material will become a single material group in Bunkspeed DriveSuite. You
cannot alter imported material groups from within Bunkspeed DriveSuite.
Hence, you must assign materials in your 3D modeling software before
exporting to OBJ.
Bunkspeed DriveSuite interprets imported material files – as well as any
texture maps, bump maps, or decals that are used in the model. After
importing the model, Bunkspeed DriveSuite allows you to edit the resulting
material parameters in the usual way, or by assigning other materials from the
Material Library.

Importing Models
Importing SolidWorks Files
Bunkspeed DriveSuite allows you to directly import native SolidWorks 2014
and prior files (SLDPRT and SLDASM).
Bunkspeed DriveSuite uses the tessellated information stored with the
SolidWorks part files. In most cases, this tessellation is fine enough for good
results in Bunkspeed DriveSuite, but close-ups may require finer tessellation.
Please refer to your SolidWorks documentation for information about refining
the tessellation of your part file and/or entire assembly. Refining tessellation
can significantly increase file size, as can importing larger assemblies. Make
sure that your computer has enough RAM and other resources to handle
large files. Importing and rendering larger files may affect system
performance.
When importing a single part file, Bunkspeed DriveSuite uses the materials
that were inside SolidWorks in order to determine the material groups.
Bunkspeed DriveSuite places identical materials into a single material group.
Objects with no assigned materials will use a single material group.
When importing an assembly file, Bunkspeed DriveSuite assigns an
individual material group to every part in the assembly, as well as any material
that is contained within the individual parts. Identical parts will be grouped into
a single material group.
Upon import, Bunkspeed DriveSuite interprets any materials described in the
SolidWorks file, including texture and bump maps that have been applied in
SolidWorks. Bunkspeed DriveSuite stores all necessary information in a BIF
(Bunkspeed Interactive Format) file.
Importing Drive Pro/ENGINEER, Pro/E, and CREO Files
Bunkspeed DriveSuite support a Drive Pro/E plugin which allows you to
launch your model directly from Drive Pro/E into DriveSuite. You can get the
plugins for importing these formats on Bunkspeed’s web site.
Importing Rhino Files
Before importing Rhino files (3DM format, version 5 or earlier), make sure that
your individual parts and material groups are on individual layers in Rhino.
Bunkspeed DriveSuite converts individual layers to different material groups.
In addition, you will need to assign material to all objects by layer.
Importing SketchUp Files
When importing SketchUp files (SKP format, version 8 or prior), Bunkspeed
DriveSuite takes the geometry and color information, along with all applied
textures, and brings them into Bunkspeed DriveSuite. All textures are kept in
a separate folder together with the original SketchUp file in the original
location.

Transforming Models
TRANSFORMING MODELS
There are several ways you can transform (i.e. move, rotate, and/or scale) 3D
models in the open Bunkspeed DriveSuite project:
•
Numerical Transforms
•
Using the Transform Manipulator
All transforms are relative to pivot point of the model. (The pivot point of the
model is determined by the external modeling software used to create the
model.) In the drop-down menu of the Transform Manipulator,
– if you select Absolute Mode, transforms are relative to a copy of the
world axis at the pivot point of the model;
– if you de-select Absolute Mode, transforms are relative to the
model’s local axis and pivot point.
Numerical Transforms
Numerical transforms allow precise translation, rotation, and scaling of a
model. You control numerical transforms with the Model Tree and Transform
parameters in the Model Tab of the Palette. (The Model Tree lists all the
models in the open project, and the parts in each model.)
1. In the Model Tab of the Palette, LEFT-CLICK the name of the target
model in the Model Tree to select the model. Be sure to select the entire
model, not just one part or just the root node.
– Alternative: Select the Model Selector in the Toolbar, and then
DOUBLE-CLICK the target model in the 3D Viewport.
2. In the Transform section of the Model Tab, you can modify the position,
rotation, and scale of the selected model as follows:
– Position XYZ: changing these values causes the model to move
along the selected axis (from left to right: X, Y, Z). For example,
entering “5” in the X-field causes the model to move 5 units along Xaxis of the project’s coordinate system.
– Rotation XYZ: changing these values causes the model to rotate
around the selected axis (from left to right: X, Y, Z). For example,
entering “90” in the Y-field causes the model to rotate 90-degrees
around the Y-axis of the project’s coordinate system.
– Scale XYZ: changing these values unequally distorts the model (i.e.
entering different values in the (X, Y, Z) fields scales the model by a
different amount along each axis).
– Scale All: changing this value to something other than “1” causes
the model to grow or shrink proportionally. For example “2” will double
the size of the model, and “0.5” will half its size.
For a comparison of numerical and visual transforms, see the table in the next
section.

You can transform a model visually with the Transform Manipulator. Visual
transforms are quick and easy, but not as precise as numerical transforms.
1. Activate the Model Selector Tool in the Toolbar, and select the target
model in the 3D Viewport. (You can’t transform individual parts separately
from their parent model.)
2. Activate the Object Manipulation Tool in the Toolbar, and select the Move

relative to its root node.
ADDING PHYSICS TO MODELS
Dynamic physics can be applied to all models. Vehicles models that have
properly set up joints for wheels and brake calipers support vehicular physics,
so you can drive them around.
Assigning Physics to Models
When you select a model, its Physics parameters appear in the Object
Parameters section of the Model Tab in the Palette. Use these parameters to
assign physics to selected models. If you’re setting up a vehicle for driving,
then set the Physics Type to Car.
Once you have assigned physics to models, you can start and stop realtime
physics simulation by toggling the Power button in the animation Timeline.
The Timeline also provides you with the means to record and play back
dynamic interactions between models and the ground.
Building Wheels and Calipers for Vehicles
In this section, you will learn how to build joints for the wheels and brake
calipers of an existing car model with 4 wheels. Building these specialized
joints differs from building normal joints. Correctly building joints for wheels
and calipers is critical to animating and driving cars in general.
LOAD THE CAR MODEL
1. Open or import a car model with parts for wheels and their components,
and dependent parts for brake calipers.
ORIENT THE CAR
In order to correctly apply joints to wheels and calipers, the car must be
oriented in a very specific way. You cannot use the Move Manipulator to do
this orientation. To establish the proper location and rotation of the model’s
node states, you need to use the Vehicle Setup
2. Select the car model.
3. In the Vehicle Setup section of the Model Tab, select the Vehicle Facing
axis to match the direction the front of the vehicle is facing towards.

Adding Physics to Models
NOTE: You can see the axes in the Viewport by displaying the world
origin (i.e. right-click in the 3D View and toggle on World Origin from
the drop-down menu). Alternately, you can use the Move Manipulator
as a visual reference, but do not use the Manipulator to move the car!
SELECT THE WHEELS
Car models typically have many parts. It would be tricky to surgically select
each part of the wheels and calipers directly. To simplify this task, first select
and hide all the parts that are not related to the wheels and calipers. Think of
it as an inverse selection:
4. Enter Camera Mode.
5. In the Camera Tool Panel, click the Side button to get a side view of the
car model, which happens to be located at the World Origin. Then zoom
in so the side view of the car fills most of the 3D View.
6. Switch to Parts Mode (a sub-mode of Model Set), and activate the Parts
Selector Tool.
7. Click-hold and drag a selection box around the center of the car, from
above the roof to below the undercarriage. Be very careful to keep the
box narrow enough to avoid selecting any part in the wheels or calipers.
8. Press Ctrl-H to hide the selected parts.
9. Repeat the previous two steps to select and hide all other parts, except
for the parts composing the wheels and calipers. When you’re done, the
only visible parts should be in the wheels and calipers.
10. Select every part in the wheels – including brake rotors, rims, nuts, etc –
except the calipers. The calipers typically rotate with the wheels when the
steering is turned, but do not spin with the wheels.
BUILD WHEELS
This subsection tells you how to build joints for wheels.
11. With the wheels selected, click Create Wheels from Selected Parts in
the Vehicle Setup section of the Model / Parts Palette. This builds the
joints for the wheels.
SELECT AND BUILD BRAKE CALIPERS
Brake calipers and wheels both need to be animated, but not in quite the
same way: Calipers turn left and right with the front wheels, but calipers do
not spin with the wheels. Here’s how to build joints for calipers:
12. Middle-click anywhere in the 3D View to de-select all.
13. Enter Parts Mode (a sub-mode of Model Set), and take a look at the
thumbnails in the Parts Palette. Notice that the thumbnails for hidden
parts are greyed out.
14. To select the calipers and their logos, hold the Ctrl-Key and click on each
and every thumbnail for the caliper parts in the Model / Parts Palette:

the calipers.
16. Right-click in the 3D View and select Show All from the drop-down menu.
The entire car should become visible again.
17. Save your project.
DRIVING VEHICLES
Once you have built the wheel joints and brake caliper joints, and you have
set the Physics Type to Car, you should be able to use the Wheel Turn
parameter to turn the wheels and calipers with them.
You can drive vehicles with an Xbox controller. Or you can use some of the
Physics parameters (in the Physics section of the Model Tab in the Palette) to
activate one of the provided Driving Behaviors, as follows:
•
Driving Behavior = Straight: Then, in Animation Timeline, click ON the
Physics button in the upper right. The car will drive itself forever. You can
influence the driving physics it in real-time by messing with the Physics
parameters in the Model Palette. You can manually move your camera as
the vehicle drives, or set the camera (in the Camera Palette) to “follow”
the vehicle’s model.
•
Driving Behavior = Turn: The car drives itself forever in a circle.
•
Driving Behavior = Path gives you 4 waypoints. You can move these
waypoints like any object (e.g. with Move Tool), and add additional
waypoints if desired, to make your own driving course. Uses AI and
realistic physics.
You can optionally record physics-based driving by activating the Record
button in the Timeline. You can render out animations in any render mode.
HIDING / SHOWING MODELS AND PARTS
If your source model has parts defined in it, then Bunkspeed DriveSuite will
preserve these parts when you import the model. In DriveSuite, you can
selectively hide and show individual parts on the models in your project.
Hiding parts selectively is very useful when applying materials to layered
objects and isolating parts for individual renderings. Here’s how:
•
Copyright © Bunkspeed, Inc. 2002-2014
To show / hide models or parts: In the Model Tab in the Palette, select the
target model or part in the Model Tree, and toggle the Hide check box.
Alternatives using the context-sensitive menu (see figure):
– To hide a model, use the Model Selection Tool to RIGHT-CLICK the
target model in the 3D Viewport, and then select Hide Model from
the context sensitive menu.
– To show all models and parts in the loaded project, RIGHT-CLICK

MORE ABOUT PARTS
When a material with a texture is mapped to a specific part, some of the
mapping properties are inherited from the definition of the material. You can
further refine the mapping of the material onto a part you have actively
selected in a model. You can also modify the normals in the part, and control
Symmetry. Here’s how:
Symmetry
Symmetry mirrors the selected part across the specified axis. This is useful for
symmetric objects because you can import just half the model (have the
number of triangles) and instance their symmetric data.

Part/Normals Control
Part and normals control reconstructs normals. This process often solves
flipped normals as well as badly formed normals common in Sketchup files
and lesser quality data.
•
Part/Normals Control:
– Faceted: Rebuilds normals with hard edges between the polygons
» Angle: Lets you choose how sharp of an edge to maintain
– Smooth: Rebuilds the normals with a blended joint between polygons,
yielding a softer surface description
– Rebuild Normals: Executes the rebuild process.
– Repair Normals: Aligns normals without rebuilding the texture verts.
– Split Part: See Splitting Models and Parts, next.
– Extract Part: See Splitting Models and Parts, next.
Splitting Models and Parts
A “part” is a grouping of one or more pieces in a model. Each piece is also a
part which can be composed of still smaller pieces, etc. Pieces don’t have to
be physically next to each other to be grouped together.
Here’s how you split parts into smaller pieces:
1. Right-click a part in the open scene using the Selection Tool. (Alternately,
In the Models Tab of the Palette, click the thumbnail of the target part to
select it.)
2. In the right-click menu, select Extract Part. The Part Splitting dialog
appears. (Alternately, you can select Extract Part from the Model Tab.)
3. In the Part Splitting dialog, adjust the tolerance of part splitting via the
Facet Angle Tolerance setting and the slider next to it. To preview the
tolerance settings, left-click the target part and continue the adjustments.
4. When ready to execute the split, right-click the target part again.

Texture Mapping on Parts
The Model Tab in the Palette includes the following Texture Mapping
parameters, which appear when you actively select a part in the open model:
Copyright © Bunkspeed, Inc. 2002-2014
•
Mode: Determines how the selected texture is projected onto 3D
surfaces. Each of the following types of texture mapping includes its own
parameters for controlling the mapping. (For illustrations, see Texture
Mapping on Parts using the Texture Manipulator.)
– UV: If your object does not have UV coordinates, its textures may not
show up initially. Fix by changing projection type.
– Box: Uses a “box” projection.
– Planar (X, Y, Z): Projects a flat texture plane in the X, Y or Z-axis. To
determine the direction, turn on the coordinate system in the Image
Tab, or use [SHIFT] + C. If the surface you would like to map to is at
an angle, you may want to rotate the model so it aligns with the
direction of the projection. After mapping, move the object back to its
original position, and the mapping will move with it.
– Spherical: Uses a spherical projection with Y being the up-axis. If
your object requires spherical mapping in a different direction, rotate
the object to align with the projection direction. Move the object back
to its original position after mapping.
– Radial: Projects the texture as a circular plane, like a circular version
of Planar.
– Cylindrical: Projects the texture as a cylinder standing up (ydirection) for mapping. If your object requires cylindrical mapping in
any other direction, rotate the object to align with the projection
direction. Move the object back to its original position after mapping.
– Perspective: Maps the texture from the current camera angle so that
it maps perfectly, but ONLY from the current camera.
•
Manipulate Texture: Lets you visually shift, scale, and rotate the selected
texture on an applied surface using the Texture Manipulator, which is a
type of Transform Manipulator that acts on textures in materials. For
details, see Texture Mapping on Parts using the Texture Manipulator.
•
Fit to Part: Sizes the texture projection to the bounding box of the
selected part. This option typically yields the best quick fit, and gives you
a good starting point to continue editing the placement of the texture.
•
Set to World Scale: Sets the texture scale to world coordinates so that
when that particular texture is applied to multiple parts and each part is
set to World Scale, then the texture pattern becomes a consistent size on
each on of those parts. It will also update on each part when the texture
properties such as a tiling, repeat and rotation is changed.
•
Transform: Lets you numerically modify the texture mapping on the
selected part. The alternative is Texture Mapping on Parts using the
Texture Manipulator, as discussed in Manipulate Texture above.

TEXTURE MAPPING ON PARTS USING THE TEXTURE MANIPULATOR
The Texture Manipulator modifies the 3D projection of a texture in a material,
prior to the texture being converted to (U, V) coordinates on the surface of the
part the material is applied to. This approach is quite different than using
Texture Parameters such as Tile, Shift, and Rotation to adjust texture
mapping, because the latter parameters act in (U, V) space after the
projection has been applied to the surface of the target part.
The Texture Manipulator functions much like the Transform Manipulator. The
obvious difference is that the Texture Manipulator operates on textures in
materials, and the Transform Manipulator operates on models.
Another key difference is that the Texture Manipulator combines the Move
and Scale Transform Manipulator into a single control. Translation and
rotation operate the same for both controls, but the scale operates differently
on the Texture Manipulator control.
The following instructions apply only to parts that have mapped materials
using textures:
1. Enable the Texture Manipulator, which you can do in 2 ways:
– Use the Selector Tool in Material Mode to select a part in a model. It’s
parameters will then appear in the Material Tab of the Palette. Then,
under Texture Mapping, select the Manipulate Texture button.
– In the Toolbar: If the Selector Tool is in Material Mode, activating the
Move Transform Tool displays the Texture Manipulator.
2. To scale with the Texture Manipulator, simply LEFT-CLICK-HOLD one of
the boxes at the corners of the manipulator, and drag the mouse.
3. To translate and rotate with the Texture Manipulator, follow the
instructions for Using the Transform Manipulator on a part instead of
the model itself – bearing in mind that translation and rotation will affect
the texture projection.

Display The Material Library
Working with Materials
Bunkspeed DriveSuite comes with a library of pre-defined materials that you
can apply to 3D models in your Bunkspeed DriveSuite projects. You can also
create new materials quite easily. This chapter describes how to work with
materials.
For details on the types of materials that come with Bunkspeed DriveSuite,
and the properties of each type, see “Types of Materials in Bunkspeed
DriveSuite” on page VII.
DISPLAY THE MATERIAL LIBRARY
To display the Material Library (shown to the left), select the Library Tab in
the Palette, and then select Materials from the drop-down menu near the top
of the Library Tab.
APPLY MATERIALS
You can add an existing material to the open project in two ways: apply a
material in the Material Library to a model; and load a material from a model
into the Material Tab (i.e. into the project). Once a material is part of the open
project, you can then Apply Materials to Parts in Models.
Copyright © Bunkspeed, Inc. 2002-2014
•
A “part” is a subset of a model. A complex car model could have
thousands of parts, for example: Each of the 4 wheels could be a
separate part, and each wheel part could be composed of smaller parts
for the metal rim, rubber tire, lock nuts, and brake rotors.
•
You cannot define parts in Bunkspeed DriveSuite. Parts are defined in the
3D modeling software used to create the original model. When you import
a model with parts into Bunkspeed DriveSuite, the parts will be preserved.
•
A material in the open project is totally independent from the materials in
the Material Library:
– The materials in the open project are saved in the BIF file with the
rest of the assets in the project (e.g. models, HDR images,
backplates, cameras, etc.)
– The materials in the Material Library are the files in the Bunkspeed
Content \ Materials folder, by default.

Apply Materials
•
When you apply XYZ material in the Material Library to a model / part in
the open project, DriveSuite adds the XYZ material to the project. If you
then edit the XYZ material in the project, via the parameters in the
Material Tab of the Palette, then the copy of the material in the project will
be affected, but the source material in the Material Library will be
unaffected. The reason is that materials in the project and those in the
Material Library are totally independent of each other (even if they have
the same names and parameter values).
•
When you open a project containing materials that are not in your Material
Library, then the new materials will appear in the Material Tab of the
Palette. To add such a material to your Material Library, simply select the
target material in the Material Tab, and LEFT-CLICK Save Material To
Library.
Apply Materials to Parts in Models
The process in this case varies slightly depending on whether your source the
material from the Material Library or the materials already in the open project,
as explained below.
USE A MATERIAL IN THE MATERIAL LIBRARY
To apply a material in the Material Library to a part of a 3D model, do the
following:
1. Display The Material Library.
2. DRAG-AND-DROP the desired material from the Material Library onto the
target part of the 3D model.
USE A MATERIAL IN THE OPEN PROJECT
To apply a material in that’s already in the open project to a part on a model,
do the following:
1. LEFT-CLICK the Material Tab in the Palette to activate Material Mode and
access a list of materials in the open project.
2. DRAG-AND-DROP the desired material from the Material Tab (not the
Material Library in the Library Tab) onto the target part of the 3D model.

Creating, Editing, and Sharing Materials
CREATING, EDITING, AND SHARING MATERIALS
Bunkspeed’s materials are fundamentally different than shaders found in
traditional rendering applications. All the materials in Bunkspeed DriveSuite
are scientifically accurate. It therefore requires far less guesswork to create or
edit a Bunkspeed DriveSuite material to have the properties you’re after.
When you create or modify materials, the changes are saved in the BIF file for
the open project, and the new or modified materials are listed in the Material
Tab of the Palette. Creating or editing a material in the Material Tab does not
add the material to the Material Library. To add such a new or modified
material to your Material Library, simply select the target material in the
Material Tab, and LEFT-CLICK the Save Material To Library button.
Create and Edit Materials
Creating a new material, and editing an existing material, are nearly identical
procedures:
1. To create a new material, RIGHT-CLICK in the Material Tree of the
Material Tab in the Palette, and select New Material from the context
sensitive menu.
1. Or, to edit an existing material, LEFT-CLICK the desired material in the
Material Tree to select the material, and then change the values of its
parameters.
Note: If you first apply the new or modified material to a model in the open
scene, then you can more clearly see the visual effects of changes to the
material’s parameters. To do so, DRAG-AND-DROP the target material
from the Material Tab to a part in a model in the open project.
2. In the Material Tab of the Palette, ensure that the target material is
selected, and then change the Material Type parameter, if necessary, by
selecting the target type from the drop-down menu.
– Each type of material has unique parameters. You can change the
values of these parameters, but you cannot change which
parameters are available except by switching to a different type.
Hence, you should first decide upon the target type of the new or
edited material before changing any of its parameters.
– For details on the types of materials that Bunkspeed DriveSuite
supports, and the parameters of each type, see “Types of Materials
in Bunkspeed DriveSuite” on page VII.
3. In the Material Tab, you can edit the values of the Material Parameters for
the selected material, as desired.
4. Also in the Material Tab, you can optionally assign textures to your
materials, as described in the next section.
5. Once you finish editing a material, you can optionally add it to the Material
Library, as follows:
i. Select the target material in the Material Tab of the Palette, and LEFTCLICK the Save Material To Library button.

Working with Materials
Creating, Editing, and Sharing Materials
Regardless of whether or not the material originated in the Material Library,
saving it from the Material Tab to the Material Library adds the modified
material to the Library as though it were a totally new material.
Add and Edit Textures in Materials
You can optionally use almost any 2D image as a texture that can be added to
a material. When a material with textures is applied to a part of a model,
DriveSuite maps the textures on the part according to the properties of the
textures. Here’s how:
1. In the Material Tab, select the target material in the Material Tree.
2. LEFT-CLICK the Color, Specular, Alpha, or Bump channels in the Material
Tab to display the Import Textures dialog. (See the figure to the left.)
– ALTERNATIVE: Drag-and-Drop a 2D image from your desktop, email,
or similar source, to the target Part of a model in the open scene.
Then select which channel to apply the texture to (e.g. Color, etc).
– With Color textures, non-transparent materials can use a 2D texture
instead of a base color. However, Some types of materials, such as
Emissive, multiply the base color by the Color texture RGB values.
– If you are adding an Alpha texture with transparency, Bunkspeed
DriveSuite uses the transparency channel in the Color texture only.
3. In the Import Texture dialog, locate and select the target texture.
– Note: You can use any 2D image in a supported format such as JPEG
or TIFF, among others. However, if your texture contains
transparency, you must use a format such as PNG that supports an
alpha channel.
– For a list of supported texture formats, see “Import Formats for
Backplates and Textures” on page VI.
4. After a texture has been added to a material, you can display most of its
parameters in the Material Tab by selecting the icon of the material in the
Material Tree; or by using the Material Selector Tool to select a part that
the material has been applied to.
– Note: You can control how the texture is applied to a specific part in a
model by selecting that part. For instructions, see “Texture Mapping
on Parts” on page 79.
5. In the Material Tab, when you select a texture in a material, you an edit its
parameters as discussed in Material Tab.
MAPPING TEXTURES
If you select an applied material on a part in a model, and the material
includes textures, then you can customize its texture mapping in these ways:
– Visually with the Texture Manipulator, as explained in Texture
Mapping on Parts using the Texture Manipulator;
– Numerically using basic UV mapping, as explained in “Texture
Parameters” on page 43;
– Numerically using more advanced types of mapping, as discussed in
“Texture Mapping on Parts” on page 79.

Share Your Materials
It’s easy to share your materials with others. Bunkspeed DriveSuite saves the
materials in your Material Library in BMF files. These BMF files are located in
the Materials Library, which is contained in the Bunkspeed Content \ Materials
folder by default.
1. To share materials with others, just give them copies of the BMF files in
your Material Library. BMF files can be emailed.
When the recipients save your BMF file into their local Material Library folder,
they will be ready to use your materials in their next Bunkspeed DriveSuite
session.
DECALING
Decals are materials with a texture that includes a transparency channel, so it
shows through whatever is under it. Decals are commonly used to put logos
on top of other materials, for example.
Creating Decals
The texture that you load for a decal should use a transparency channel to
define the areas in the decal that should be transparent:
1. To create a decal, right-click a new blank material the tree of the Material
Tab, and select New Decal from the context-sensitive menu (see figure).
2. In the file browser that appears, locate and load a decal texture.

Working with Scenes
In Bunkspeed DriveSuite, you use High Dynamic Range Images (HDR) as
the light source for your projects. How? Bunkspeed DriveSuite maps an HDR
image of your choice onto a spherical environment that envelops your models
like a giant bubble. The HDR image thereby radiates light into the scene
according to the RGB values of each and every pixel in the image. This
technique closely simulates real world lighting, even when wide contrast
ranges are called for.
When you right-click in the tree near the top of the Scene Tab, options appear
for loading new HDR images, lights, and backplates.

CREATE AND EDIT HDR ENVIRONMENT IMAGES
A single High Dynamic Range Image (HDR) provides realistic lighting for
projects created in Bunkspeed DriveSuite. For instructions, see Load a HDR
Environment Image, next.
Load a HDR Environment Image
Loading a new HDR image into an environment replaces the old HDR image.
Once loading completes, you will see the lighting in your scene change to use
the light from the new HDR image.
1. Select Project > New HDR Environment from the Main Menu.
2. In the Open Environment dialog, navigate to the desired HDR file and
open it. The HDR image loads into the environment of your scene.
•
Alternative: To apply a previously loaded HDR image to your project,
DOUBLE-LEFT-CLICK the icon of the desired image in the Scenes Tab.
•
Alternative: In the Scenes Tab of the Palette, RIGHT-CLICK within the
Environment Tree near the top (which lists the environments saved with
your project), and select New HDR Environment.
Tune HDR Environment Images
Upon import, Bunkspeed DriveSuite preserves the brightness and gamma
settings in the source HDR file. After import, you can change these settings,
as well as make other adjustments to the environment, in the Environments
Tab of the Palette.
To display all the tools, left-click the Tools button in the Quick Start bar, or leftclick the expansion bar on the far right edge of the Bunkspeed DriveSuite
Window. Then select the Scenes Tab to display Environment Tools.
SHOW / HIDE THE ENVIRONMENT
To toggle the visibility of the environment image, LEFT-CLICK the Show
Environment Image check box in the Scenes Tab of the Palette when the
target Environment icon is selected therein. Notes:
•
Even when hiding an HDR environment image from direct view, the image
continues to radiate light into the project as well as reflect visibly off shiny
surfaces.
•
When an environment image is hidden, and a backplate (if any) is also
hidden, the color of the background is defined by the Background Color
parameter in the Scenes Tab.
TRANSFORM THE ENVIRONMENT
By default, the HDR image used in a Bunkspeed DriveSuite environment is
mapped onto a sphere with a radius of 25 meters centered at the world origin.
The sphere envelops your entire project with HDR light that very closely
simulates the light in real world environments.

Bunkspeed Drive Suite User Guide
Working with Scenes
Create and Edit HDR Environment Images
You can rotate, scale, and offset the environmental sphere, relative to the
world origin. See the subsections below for details.
Rotate the Environment
To rotate the environment, and thereby change the direction of light radiated
by the environment image, edit the Rotation parameter in the Scenes Tab of
the Palette. Rotation is in degrees.
Scale the Environment
To make the environmental sphere whatever radius you wish, within reason,
change the Size (meters) parameter in the Scenes Tab of the Palette.
Offset the Environment
To vertically offset the environment image relative to the world origin, edit the
Height (meters) parameter in the Scenes Tab.
ADJUST BRIGHTNESS AND GAMMA
You can adjust the brightness and gamma of the light emitted by the
environment image in your project. For details, see the sections below.
Environmental Brightness and Gamma
Modifying the brightness of the environment image changes the exposure of
the image. (Note: Bunkspeed DriveSuite changes brightness and contrast in
real-time. The source file of the environment image is not altered.)
Changing the exposure of the environment image alters the luminance (i.e.
intensity) of the light the image radiates into your open project. (Note:
Everything except backplates images are affected by the light emitted from
the applied HDR environment image.)
Modifying the gamma of an environment image changes contrast indirectly.
Altering gamma also change brightness, but in a very different way than the
Brightness parameter. Although gamma is not the same as contrast, you can
use gamma to adjust contrast, while using brightness to adjust luminance.
Used together, these two controls enable you to fine tune the combined
brightness and contrast of the lighting in your project.
Because HDR images have so much data (32-bits per channel of RGB data),
they have a very wide contrast range. Hence, small changes to the brightness
and contrast of an HDR image usually produces high quality results.
1. Display the Environments Tab in the Palette.
2. In the Environments Tab, change the Brightness parameter and observe
the results in the Realtime View. Higher values increase brightness; lower
values decrease it.
3. Change Gamma in the Environments Tab, and observe the results in the
Realtime View. Higher values decrease contrast and increase brightness;
lower values increase contrast and decrease brightness.

DISPLAY SHADOWS
Bunkspeed DriveSuite can calculate the shadows that each 3D model casts

performance due to the increased number of calculations required.
1. To enable or disable ground shadows, toggle on the Ground Shadow
parameter in the Scenes Tab of the Palette.
2. Optionally use the Shadow Intensity Slider to darken or lighten the
environment ground shadow.
DISPLAY CAUSTICS AND SHADOWS ON GROUND PLANE
To display caustics and shadows from physical light sources on the artificial
ground plane, max out the Ground Reflection and Ground Glossiness values.
FLATTEN THE GROUND
HDR images are spherical by default, with the equator corresponding to the
imaginary level of the ground. Flattening the ground converts the environment
sphere to a half-sphere. The image is re-mapped to the resulting half-sphere,
and the bottom becomes a visible ground.
•
To flatten the ground of an environmental sphere, toggle on the Flatten
Ground parameter in the Environments Tab.
Create and Edit HDRI Environments in HDR Light Studio
Create an HDRI in HDR Light studio by selecting the New HDRLS

2. In the Toolbar, select the Move Manipulator Tool. To select the light, click
on either the icon for the light source or its look-at point in the scene.
(Alternatively, you can select the light’s icon in the Scene Tab.) The
properties of the selected light appear in the Scene Tab.
3. Optionally edit the Light Parameters in the Scene Tab.
4. Using the Move Manipulator, you can move the selected light in the open
scene, as follows:
– Click-hold and drag the blue ring by +22.5 degrees to rotate the light
around the Z-axis.
– Click-hold and drag the green ring to rotate the light +90 degrees
around the Y-axis (green arrow).
– Click-hold and drag the grey arrow to bring the light closer to its lookat point, until the light icon is within view.
You can optionally create multiple lights by repeating the above procedure.
Note that multiple lights can substantially reduce real-time performance and
add to rendering times.
Note that you can set the ground shadow to form from spot or point lights only
if a ground plane is present.
CREATE AND EDIT BACKPLATE IMAGES
A backplate allows you to load a high resolution 2D image in the background
of your Bunkspeed DriveSuite project. Once loaded, the backplate image
always remains in the background no matter where you move the camera.
3D models in the scene retain the lighting specified by a HDR environment
image, without influence from the backplate image. Backplate images do not
emit light in your scene, do not cast shadows, and do not reflect in shiny
surfaces. They just look great in your background.
Loading Backplate Images
To load a new backplate image into your Bunkspeed DriveSuite project, or
replace the current backplate image, do the following:

Loading a new image into the background of your scene replaces the old
backplate image, if any.
If you edit the source image for the loaded backplate using software such as
Photoshop, the backplate in your Bunkspeed scene will automatically update
– provided that you’ve turned on Auto-Update in the Scenes Tab of the

Create a New Sun and Sky Environment
Working with Animations
In the most general sense, animation is visual change over time.
In most animation software such as Bunkspeed DriveSuite, you create a
simple motion animation by recording the desired starting position of an object
at a specific time, and then recording the desired ending position of the object
at a later time. These two positions are called keyframes. The software can
then calculate the intermediate positions of the object between keyframes in a
process called interpolation.
For example, you can use Bunkspeed DriveSuite to create a cube at the world
origin. Next, right-click and select Add Keyframe to create the starting
keyframe with the cube at the origin of the scene. Then use the Move
Manipulator to move the cube elsewhere in the scene. Adjust the time in the
Timeline to 2 seconds, and select Add Keyframe again from the right-click
menu. If the timeline is set to 30 fps, then the application interpolates
intermediate positions of the cube over 60 frames in 2 seconds.
Using the Move, Rotate, and Scale Manipulators in the Toolbar, you can
transform an entire model set, an individual model, an individual part, a
camera and a light in much the same way. (Note: If you wish to rotate an
object more than 180 degrees, use a Rotation Animation instead of a regular
keyframe.)
In the case of cameras and lights, you can change additional properties from
one keyframe to the next (e.g. depth of field, focal length, light color and
intensity, etc). In the case of materials, you can change all material properties
between keyframes, except for textures (which cannot be animated).

KEYFRAME ANIMATION
In Bunkspeed DriveSuite, you can animate entire Model Sets, individual
models, individual parts, materials, lights, and cameras. The process for
animating these items is described in this chapter.
The instructions in this chapter make extensive use of the Animation Controls
and Timeline (shown below). For detailed descriptions of each control, see
“Animation Timeline and Controls” on page 60.

About Splitting Parts into Pieces
It is possible to animate the pieces of parts separately from each other by
splitting a part into pieces first. For instructions. see “Splitting Models and
Parts” on page 78.

Keyframe Animation
Assign Parts to Groups
This section describes how to group parts, so you can animate the group
together. Parts do not have to be near each other to be grouped.
1. Begin by selecting the individual parts to group. To select multiple items
one at a time, Ctrl-Click each item. Alternately, you can drag a selection
box over the target items.
2. Right-click in the Tree of the Model Tab, and select Make Group.
Move Pivot Points
Every model, part, or similar item has a pivot point around which it moves.
Sometimes you need to move default pivot points so selections will animate
the way you wish:
1. Set the Object Manipulation Tool to Pivot mode.
2. Select the target part, group, or other target item in the scene. A
Transform Manipulator appears at the pivot point of your selection. (Note:
The default pivot point may not be in the location as the selected item.)
3. Using the Transform Manipulator to move and rotate the selected pivot
point to the desired location, relative to the item it’s associated with. It’s
the relative location that’s important with pivot points, not the absolute
location of the pivot point.
Animate the Selection
You can animation the selected item (i.e. entire models, individual parts,
groups of models and/or parts, materials, lights, and cameras) as follows:
1. Select the target item with the Selection Tool.
2. Right-click the selection and choose Add Keyframe from the context
sensitive menu. (For rotation animations, select Add Rotation Animation
instead.) A new animation appears in the Animation List, with the state of
the selected item recorded in the first keyframe.
3. In the Timeline, set the maximum potential end time by dragging the red
flag (end time) to the desired end time.
4. In the Timeline, drag the yellow flag (current time) to the desired time of
the next keyframe.
5. Transform the selection as desired for the next keyframe.
6. Add the next keyframe either by clicking the Key icon in the Animation
List, or by right-clicking and selecting Add Keyframe from the context
sensitive menu.
7. Repeat steps 4 - 6 to add additional keyframes to the selected animation.
8. Use the Basic Animation Controls to evaluate and play the animation.

Animation Ribbon
ANIMATION RIBBON
The Bunkspeed Ribbon is an interactive animation tool for visualizing and
editing keyframes, velocity, tension and motion ease. In this case, you will use
the Ribbon to edit an existing animation:
1. In the 3D View of the open scene, the Bunkspeed Ribbon displays the
3D path of animated items (unless you toggle off the visibility of the
Ribbon), using the current interpolation. Within the Ribbon, keyframes
appear as boxes. You can select these boxes and edit them directly using
the Object Manipulator Tool. Moving a box moves that section of the
Ribbon, which in turn customizes the 3D path of the animated item.
2. Play the animation using the Basic Animation Controls.
3. With a keyframe selected and the animation playing, experiment with
adjusting the Transition, Curve Tension and Motion Ease in the Keyframe
Properties palette.
For example, change the Motion Ease and notice that setting
“In” to maximum (+) causes the camera to slow while
approaching the selected keyframe. The color shifts on the
Bunkspeed Ribbon indicate velocity: green indicates
acceleration and red indicates deceleration.

SAVING IMAGES
In Bunkspeed DriveSuite, whenever you use File > Save Project to save a
file, Bunkspeed DriveSuite saves the open project in the Projects Library, in
its native BIF format. The BIF format packages all assets associated with the
project into a single file.
When you select File > Save Project As, Bunkspeed DriveSuite gives you
the choice of saving the BIF file to a different folder.
Bunkspeed DriveSuite can open BIF files created in earlier versions of
DriveSuite. However, once you save the project in Bunkspeed DriveSuite,
you cannot open it again in earlier versions.
OUTPUTTING IMAGES
Bunkspeed DriveSuite can output images of your projects in the following
ways by selecting the icons under the Render button in the Toolbar. From left
to right, these icons do the following:
Copyright © Bunkspeed, Inc. 2002-2014
•
Snapshot (High Speed) quickly captures what you see on your screen
with a lot more user control than an ordinary screen shot.
•
Render (High Quality) invokes raytracing at the quality and other custom
settings that you specify. Several rendering modes are available.
•
Animation renders a movie of the animations you have set up in the
open scene.
•
Turntable renders a series of frames showing your object(s) spinning on

Render (High Quality)
Bunkspeed DriveSuite can generate high quality renderings that are
incredibly realistic, but it can take some time depending on your hardware, the
complexity of your Bunkspeed DriveSuite project, and resolution of renders.
Here’s how you make a high quality rendering of the scene that’s open in
Bunkspeed DriveSuite:
1. Click the Render Button located in the right corner of the Toolbar (or
select Tools > Render from the Main Menu).
2. In the Render Options dialog that appears, choose Render from the tabs.
3. In the Render Options (described below), select your Render Options.
4. LEFT-CLICK Start Render to start the rendering process. The HUD will
show the progress. When completed, DriveSuite will save the rendering
in the Bunkspeed Content \ Images Library by default.
RENDER OPTIONS
All or some of the following Render Options are available, depending on the
Output Mode and other choices you make in the Render Options dialog:
Output File
Copyright © Bunkspeed, Inc. 2002-2014
•
Filename: Give the file to be output a filename.
•
Output Folder: The folder where the render will be saved.
•
Image Format: Select the format of the output file from the list. (Note:
The HDR format preserves 32-bit per channel RGB data, but the other
formats do not.)
•
Output Mode: Select from the following output modes:
– Render: Renders a single image using the current camera.
– All Cameras: Renders a single image using each and every camera
in the open scene – producing the same number of renderings as you
have cameras in the scene.
– All Configs: Renders all configurations in the project.
– Panoramic: Takes an image cube. (An image cube is 6 images taken
from the same location, pointing at 90-degree angles from each
other). Then it stitches those 6 shots together to form a 360-degree
panorama around the camera. Then it outputs an HTML file, storing
content images in a subfolder, so you can view the panorama in any
browser. You can even pivot and zoom (but not pan) that camera the
browser. This is very convenient for interior spaces, and can be used
with Preview and Accurate renders.
– VR: Takes lots of stills from dozens of camera locations, in multiple
orbits, to support the ability to move around the output model in any
browser. Parameters:
» Orbits: Number of camera height levels.
» Images per Orbit: Renders from each camera orbit.
» Start Angle: Lowest angle of orbit
» End Angle: Highest angle of orbit

Render Output Passes renders a single standard image if you select
“None”. Any other selection here also generates specialized output passes
that you can use in post-processing software (such as Photoshop) to
enhance the normal output pass. The drop-down options allow you to
select which output passes you would like from the following options:
– Beauty: The regular raytraced image.
– Gloss: 50% rough chrome for isolating reflections.
– Specular: 100% chrome for isolating highlights.
– Black Specular: Same as Specular, but shows the reflections over a
glossy black paint to collect the correct fresnel.
– Roughness: Renders each part based on its material roughness.
This is an advanced version of the Gloss pass which retains per
material roughness.
– Incandescent: Lights the scene using lights that have been placed in
the scene, if any, but not the HDRI environment. If no lights have
been manually placed in the scene, this output pass will be black.
– Ambient Occlusion: The same as Global Illumination, except for
collecting the shadow information from an evenly lit white
environment. With Ambient Occlusion, shadows are not colored, nor
are they directional.
– Ground Shadows: Only ground shadows.
– Global Illumination: Paints the objects in the scene flat white, and
captures internal shadowing (i.e. the object shadowing itself).
– Object: The Object pass is a black and white mask to delineate
between the 3D model in the scene vs the background.
– Depth: A depth pass renders the Z-depth of the camera in terms of
greyscale value. A depth output can be used during post-processing
to apply depth of field, fog, etc.
– Clown: Paints each part a separate flat color.
•
Include Alpha: If enabled, the output file includes an alpha channel.
Resolution
•
Resolution: The number of pixels (width by height) in the output file.

Import Formats for HDR Environments
The text below is adapted from Wikipedia:
http://en.wikipedia.org/wiki/High_dynamic_range_imaging
HDR stands for High Dynamic Range Imaging, which is a set
of techniques that allow a much greater range between light
and dark areas of an image than normal imaging techniques.
HDR is designed to accurately reproduce the wide range of
lighting levels found in real scenes from direct sunlight to
deep shadows.
Information stored in high dynamic range images usually
corresponds to the physical values of luminance or radiance
that can be observed in the real world. This is different from
traditional digital images, which represent colors that should

appear on a monitor or a paper print. Therefore, HDR image
formats are often called "scene-referred", in contrast to
traditional digital images, which are "device-referred" or
"output-referred".
Furthermore, traditional images are usually encoded for the
human visual system (maximizing the visual information
stored in the fixed number of bits), which is usually called
"gamma encoding" or "gamma correction". The values stored
for HDR images are often linear, which means that they
represent relative or absolute values of radiance or
luminance (gamma 1.0).
Bunkspeed DriveSuite uses HDR images for environments that radiate the
light in your scenes. DriveSuite supports two formats for HDR images: EXR
and HDR. Both are described below.
OPENEXR (EXR)
OpenEXR (.EXR extension) is a high dynamic range imaging image file
format that stores a vast exposure range and color depth by providing 32-bitsper-channel of RGB information.
HIGH DYNAMIC RANGE IMAGE (HDR)
High Dynamic Range Images (.HDR extension) is a high dynamic range
imaging image file format that stores a vast exposure range and color depth
by providing 32-bits-per-channel of RGB information.
Import Formats for Backplates and Textures
Bunkspeed DriveSuite can import the following 2D file types for use as
backplates or textures for use in materials. These formats cannot be used as
environmental images, and cannot emit light into your project.

TYPES OF MATERIALS IN BUNKSPEED
DRIVESUITE
Bunkspeed DriveSuite includes a material library that contains many preconfigured materials. All Bunkspeed DriveSuite materials are based on
scientifically accurate materials.
Each type of Bunkspeed DriveSuite material is defined by a unique set of
Material Parameters and Texture Properties that simulate a real material,
such as glass or leather. When you select a material in the Material Library, or
on an object, you can view and edit its Material parameters and Texture
properties in the Material Tab of the Palette.
For details on the properties of Color, Specular, Alpha, and Bump textures
that you can optionally assign to materials, see Texture Parameters. and
“Texture Mapping” on page 29. For details on the Material Parameters that
are unique to each type of pre-defined Bunkspeed DriveSuite material, see

Types of Materials in Bunkspeed DriveSuite
Anisotropic
The Anisotropic material simulates a surface with an asymmetrical specular
highlight that changes when the surface rotates, relative to the light sources.
Put another way, an anisotropic material has a "grain" or directionality. This
material is most commonly used to simulate brushed finishes on metallic
surfaces. The material’s parameters are:
•
Base Color: sets the color of the material in diffuse white light
•
Highlight Color: sets the color of the material’s specular highlights
•
Roughness: controls the size of the highlight. The rougher the material,
the more it diffuses the highlight (i.e. the larger and less focused the
highlight becomes).
•
Distortion: controls the amount of distortion by changing the ratio of
roughness in one direction on the surface, verses the perpendicular
direction. Zero causes no distortion, and 100 causes maximum distortion.
•
Angle: sets the direction of the Distortion effect.
Backscattering
Backscattering is great for fabrics. It works well with Bump map textures.
Parameters:
•
Base Color: controls the darker color of the base material.
•
Highlight Color: controls the color of specular highlights.
•
Roughness: low values for things like satin; high value for leather, velvet,
and so forth.
•
Distortion: influences the anisotropic light to achieve an effect similar to
changing the direction of the stitching in the fabric.
•
Angle: controls the light direction of Distortion (above).
Emissive
The Emissive material emits light into the scene – provided that you assign a
Color texture (the only type of texture supported by emissive materials) and
enable the Blend Texture option in the Texture Parameters of Material Tab.
If you don’t do this, then the Emissive material will reflect the light that’s
shining on it, but will not radiate any additional light into the scene – even if
you crank up the Intensity parameter very high.
•
Copyright © Bunkspeed, Inc. 2002-2014
Color: in the absence of light, the material radiates the Emissive color. In
typical scenes, the color the Generic material is the sum of Base Color
plus Emissive Color (plus Highlight Color for highlights).

Types of Materials in Bunkspeed DriveSuite
Intensity: multiplies the Color value, by adding luminance (i.e. causing
more light to be emitted by the material). Due to clipping in monitors,
adding intensity can make the Color appear washed out. To
counterbalance this tendency, add saturation to the Color value after
increasing Intensity.
Flat
The Flat material is not shaded, so it does not react to light or shadows.
Hence, the Flat material has a constant color regardless of lighting and
shadows. The Flat material is so obviously unrealistic, it is perfectly suited for
masking and such.
•
Color: sets a fixed color for the material. This color does not change
regardless of the light falling on the material (i.e. this material is not
shaded).
Generic
The Generic material can simulate a wide range of materials – making it
possible to precisely control how light interacts with a material. This material’s
parameters are as follows:
Copyright © Bunkspeed, Inc. 2002-2014
•
Diffuse Color: sets the color of the material in diffuse white light
•
Specular Color: sets the color of the material’s specular highlight
•
Transparency Color: the tint acquired by light passing through partially
transparent materials.
•
Diffusion: how much light diffuses through partly transparent materials.
•
Roughness: simulates surface roughness by controlling the size of the
highlights in reflected light. The rougher the material, the more it diffuses
highlights (i.e. the larger and less focused the highlight becomes).
•
Emission: Causes this material to emit light into the scene.
•
Internal Roughness: simulates internal roughness that affects light
refracting through the material instead of reflected off its surface.
•
IOR: directly controls how much materials with transparency bend light
passing through them; indirectly affects reflectivity.
•
Solid: toggles two-sided verses one-sided properties (e.g. IOR Out
applies only to two-sided objects)
•
Color Density: adds more of the Diffuse Color (i.e. from faint to intense)
as the object gets thicker.

Glass
The Glass material is optimized for windows. It can handle thin or thick glass.
Typical applications include the windshield and head lamps of an automobile.
This material’s parameters are as follows:
•
Solid: toggles two-sided verses one-sided properties (e.g. IOR Out
applies only to two-sided objects)
•
Color: sets the color of the material in diffuse white light.
•
IOR: sets the index of refraction (i.e. the amount of bending) of light
passing into the glass. When using a surface without thickness, the IOR
will affect the reflectivity of the surface, but the light passing through it will
not refract. On a surface with thickness, this material will cause light to
refract as it passes through the Solid object.
•
IOR Out: sets the index of refraction (i.e. the amount of bending) of light
passing out of the glass. (Note: Transparent objects with thickness, like
most gems and glass, refract light when entering and leaving the object.)
•
Thickness (mm): determines the intended thickness of the simulated
surface, compared to comparable solid glass in reality.
•
Roughness: controls the size of the highlight. The rougher the material,
the more it diffuses the highlight (i.e. the larger and less focused the
highlight becomes) – such as with frosted glass.
Gem
The Gem material is a version of the Glass material that’s been optimized for
gem stones. This material’s parameters are the same as Glass – except for
the addition of the Abbe Number parameter.
Matte
This simple material simulates matte surfaces, like flat paint with no specular
highlights. This material’s parameters are as follows:
•
Color: sets the color of the material in diffuse white light
Metal
The metal material is used to simulate metals such as aluminum, gold, and
silver, with different finishes such as polished, powder coated, cast, etc. This
materials parameters are:
Copyright © Bunkspeed, Inc. 2002-2014
•
Color: sets the color of the metal in diffuse white light
•
Roughness: determines how much the metal diffuses specular
highlights. A value of zero would cause no diffusion at all, which would
make the metal appear very smooth with sharp specular highlights.

Metallic Paint
This material simulates metallic paints such as car paints, but can also be
used to simulate multilayer plastic finishes. This materials parameters are:
•
Face Color: sets the primary base color of the paint in diffuse white light.
•
Flop Color: introduces a second color into this material. •
Travel: balance between Face Color and Flop Color. More travel means more Face Color and less Flop Color.
•
Flake Color: sets the color of the metallic flake in diffuse white light
•
Flake Roughness: the roughness off the flakes themselves.
•
Flake Coverage: the density of the metallic flakes.
•
Clearcoat: If enabled, the paint acquires a shiny wet look typical of a
clearcoat on top the metallic paint itself.
•
Clearcoat Tint: adds a transparent color on top of Face and Flop and
Flake.
•
Clearcoat Roughness: determines the degree the clearcoat diffuses
specular highlights. A value of zero would cause no diffusion at all, which
would make the clearcoat appear very smooth and shiny.
•
Physical Flakes: If enabled metallic flakes in the paint have physical
size.
•
Flake Size: the actual size of the physical flakes.
•
Flake Angle: the actual angle of the physical flakes.
Multi-Layer
The Multi-Layer type of material consists of up to four other materials stacked
on top each other to create sophisticated material renditions with ease. For
example, you could stack a Glass layer on top a Carbon Fiber layer, or a Dirt
texture map on top a Car Paint layer. You choose the materials and stacking
order.
Paint
This material simulates non-metallic paint. Parameters:
Copyright © Bunkspeed, Inc. 2002-2014
•
Color: sets the color of the material in diffuse white light
•
Clearcoat: the index of refraction (IOR) of the clear coat. It indirectly
determines the surface reflection on the clear coat.
•
Clearcoat Roughness: determines how much the clearcoat diffuses
specular highlights. A value of zero would not diffuse reflections at all,
causing specular highlights to be pinpoint sharp.

Plastic
The Plastic material is optimized to simulate many plastic types. This
material’s parameters are:
•
Color: sets the color of the material in diffuse white light
•
Highlight Color: sets the color of the material’s specular highlight
•
Transparency Color: the tint acquired by light passing through partially
transparent materials.
•
Diffusion Color: scattering of light in translucent materials, such as clear
plastic.
•
IOR: directly controls how much the material bends light passing through
it, and indirectly affects reflectivity.
•
Roughness: controls the size of the highlight. The rougher the material,
the more it diffuses the highlight (i.e. the larger and less focused the
highlight becomes).
Subsurface Scattering
This material type works only in high quality Rendering Modes. This material
is great for milk, teeth, some stones, honey, etc. Parameters:
•
Absorption: the color that’s being absorbed as light is passing through
the material.
•
Scattering: the degree of bouncing light within the material. More
scattering means more cloudy.
•
Reflection: the color of light bouncing off the surface of the material.
•
IOR: affects the reflectivity and diffraction of the surface.
•
Thickness: how thick the applied object is in real life.
Thin Film
Thin film simulates soap bubbles, oil slicks, etc. with rainbow color distortion
on the surface layer. Parameters:
Copyright © Bunkspeed, Inc. 2002-2014
•
Color: the base color of the material. Supports transparency.
•
IOR (index of refraction): the material’s reflectivity and distortion of light
penetrating it.
•
Film IOR: changes the IOR of the surface layer separately from the base.
Strongly affects color on the surface layer.
•
Film Thickness: The thickness of the overall material. Very thin films are
mostly surface layer, which tends to have strong visual effects. Thicker
films take on more of the base material’s properties, with less effect from
the surface layer.

GLOSSARY
The following glossary covers key 3D terms that you should become familiar
with before getting serious.
3D
Three-dimensional. Descriptive of a region of space that has width, height and
depth.
Algorithm
A procedure or formula for solving a mathematical problem. Algorithms are
commonly used for such tasks as generating textures, rendering images and
controlling mathematically based behavior patterns.
Alpha Channel
The top byte of a 32-bit pixel that is used for data other than color. The alpha
channel commonly holds mask data, enabling an image to be separated from
its background for use in compositing.
Ambient Light
Alpha Channel
Ambient Light
Animation
Copyright © Bunkspeed, Inc. 2002-2014
An artificial illumination level representing infinite diffuse reflections from all
surfaces within a 3D scene, ensuring that even surfaces without direct
illumination become visible to the user.
The top byte of a 32-bit pixel that is used for data other than color. The alpha
channel commonly holds mask data, enabling an image to be separated from
its background for use in compositing.
An artificial illumination level representing infinite diffuse reflections from all
surfaces within a 3D scene, ensuring that even surfaces without direct
illumination become visible to the user.
A medium that creates the illusion of movement through the projection of a
series of still images or ‘frames’. The term is also used to refer to the
techniques used in the production of an animated film - in 3D animation,
primarily those controlling the motion of the objects and cameras within a
scene. These include keyframe animation, in which the artist sets the
positions of objects manually at certain key points in the action, and the
computer calculates their intervening positions through a process of
interpolation or ‘inbetweening’, and procedural animation, in which the motion
is controlled automatically via a series of mathematical formulae.

Bunkspeed DriveSuiteUser Guide
Appendix
Glossary
Anti-aliasing
A method of reducing or preventing rendering artefacts by using color
information to simulate a higher screen resolution. The term is often applied to
the process of softening the unnaturally precise or stepped edges (sometimes
known as ‘the jaggies’) created when a computer generated object is placed
against a contrasting background by using pixels of intermediate shades as a
buffer between the two.
Aperture
In a real camera, the size of the opening that light passes through (usually
given in terms of its f-stop) in order to reach the film. The larger the f-stop, the
smaller the opening. 3D software packages sometimes mimic the effects of
different aperture settings on a recorded image during the rendering process.
Aspect Ratio
Axis
Beauty Pass
Bit Depth
The ratio of the width of an image to its height. Common aspect ratios for
broadcast images include 4:3 and 16:9 (widescreen).
A hypothetical linear path around which an object can be rotated, or across
which it can be mirrored. In the Cartesian co-ordinate system, the three world
axes, X, Y and Z (width, height and depth) define directionality within the 3D
universe. Hence, a co-ordinate of (0,0,0) defines the origin of the world.
When rendering multiple passes of a scene, the beauty pass is the one that
features the most significant information about the objects within it. This
usually includes the main, full-color rendering of those objects, including
diffuse illumination and color. A beauty pass will not include reflections,
highlights, and shadows, which are usually separate passes.
The number of bits used to define the shade or color of each pixel in an
image, a ‘bit’ being the smallest unit of memory or storage on a computer.
(One ‘byte’ is eight ‘bits’.) A 1-bit image is black and white. An 8-bit image
provides a 256-color palette. A 24-bit image provides 16.7 million possible
colors: a palette sometimes known as ‘True color’. A 32-bit image provides
the same palette, plus an 8-bit greyscale alpha channel.
Bitmap
Strictly speaking, a bitmap is a 1-bit black-and-white image. However, the
term is often loosely applied to any two-dimensional image, regardless of bit
depth. Still image manipulation packages such as Photoshop and Paint Shop
Drive are sometimes referred to as ‘bitmap editors’.
Bluescreen Footage
Live footage shot against a backdrop of a single uniform color (usually blue or
green) with a view to compositing it into a computer generated background.
Every pixel with the same color value as the backdrop is replaced by the CG
image.
Bounding Box
Copyright © Bunkspeed, Inc. 2002-2014
The smallest regular-shaped box that encloses a 3D object, usually
rectangular in shape.

Bump Map
CAD
Glossary
A black-and-white image used by a 3D software package to simulate the
three-dimensional detail on the surface of an object. When projected over the
surface of the object, parts of the surface beneath white areas of the image
are raised; those beneath black areas are depressed. Bump mapping is
purely a rendering effect, however, and does not affect the underlying
geometry of the model.
Computer Aided Design. The use of computer-based models of objects for
visualization or testing as an aid in the design process. CAD software
packages usually contain more precise real-world measuring tools than
ordinary 3D packages, but fewer surfacing and animation features.
Camera
A virtual viewpoint in 3D space that possesses both position and direction. In
a 3D scene, the camera represents the viewer’s eye. When the scene is
rendered at final quality, it is the camera view that is used, rather than the one
seen in the software’s workspace. This enables the artist to move around the
workspace without disturbing the camera view.
Camera Mapping
A technique by which geometry matching the size and perspective of objects
shown within a still image is constructed, and the original image mapped back
onto those objects. This permits limited camera movement around the picture,
giving the illusion of a 3D environment from a 2D image.
Camera Move
A movement of the virtual camera within a 3D software package analogous to
one in real-world cinematography. Common camera moves include dollying,
in which the camera angle remains fixed, but the camera moves towards or
away from the subject; panning, in which the camera position remains fixed,
but the camera tilts or swivels in any direction to follow the action; and
tracking, in which the camera moves in a single plane at right angles to the
area of interest.
Camera Path
The path in virtual space along which the camera moves during the course of
an animation.
Caustics
Patches of intense illumination caused by the refraction of light through a
transparent object or the reflection of light from a reflective surface. One
common example would be the shifting patterns of light and shade cast on the
floor of a swimming pool on a sunny day. Rendering software has only
recently become sophisticated enough to mimic such complex real-world
lighting effects as caustics.
CGI
Copyright © Bunkspeed, Inc. 2002-2014
Computer Generated Imagery. An image or images created or manipulated
with the aid of a computer. The term is often used to refer specifically to 3D
computer animation, although it is really more widely applicable.

Appendix
Glossary
Channel
For a two-dimensional image, a channel is a sub-image composed only of the
values for a single component of a given pixel. A greyscale image has one
color channel, an RGB image has three, and a CMYK image has four. When
applied to materials, the term refers to one particular subset of the properties
which determine the way in which a surface reacts to light, including color,
reflectivity, transparency, diffusion, specularity and bump.
color Bleeding
A physical phenomenon by which the color of one object is seemingly
transferred to a neighboring object by light bouncing from one surface to the
other. Like caustics, color bleeding is a complex real-world lighting effect, and
one that rendering software has only recently become able to simulate
accurately.
color Space
A mathematical method for defining the way in which color is represented
within an image. Common color spaces include RGB (Red, Green, Blue),
which has a bit depth of 24, and is commonly used in broadcast applications,
and CMYK (Cyan, Magenta, Yellow, Black), which has a bit depth of 32, and is
used for print illustration work.
Compositing
The process of combining multiple images into a single image. This is often
performed in films to make a live actor appear on a computer generated
background, or vice versa. It can also be used following multi-pass rendering
to combine the various render passes in different ways to control the look of a
scene.
Compression
A technique for reducing the quantity of data required to make up a digital
image. Compression techniques can be non-destructive (‘lossless’) or
destructive (‘lossy’), in which part of the data set is discarded permanently.
Converting still images into JPEG format is one example of lossy
compression.
Constrain
Co-ordinate System
Copyright © Bunkspeed, Inc. 2002-2014
To restrict the motion of an object to one or two planes, or to a certain range of
values within a plane, in order to simplify the process of animation.
Constraints are commonly imposed on joints within a skeleton during the
process of rigging a character for animation, in order to prevent that character
from performing actions that would be physically impossible.
A set of numerical values used to denote a location in 3D space. In the
Cartesian co-ordinate system, three orthogonal ‘world axes’ (the X, Y and Z
axes) are used to define the position of a point relative to the intersection of
these axes, or origin. Other co-ordinate systems can be used for modelling
and texture projection.

DoF
Depth of Field. The depth of field of a specific lens is the range of acceptable
focus in front of and behind the primary focus setting. It is a function not only
of the specific lens used but also of the distance from the lens to the primary
focal plane, and of the chosen aperture. Larger apertures will narrow the
depth of field; smaller apertures will increase it.
Environment Map
An image intended to entirely enclose a scene, either to provide a convincing
background, or to project real-world lighting or reflection data onto the surface
of an object.
Extrusion
Face
A modelling technique in which a two-dimensional outline or profile is
duplicated outwards along a linear path, and the set of duplicated profiles
joined to create a continuous three-dimensional surface.
The front or back of an extruded object. The shape from which a 3D object
has been extruded.
Fall-off
The way in which the intensity of a light diminishes with the distance from its
source. In the real world, the fall-off of light is governed by the inverse square
law, which states that the intensity is inversely proportional to the square of
the distance. However, in 3D software packages, it is possible to use a variety
of different mathematical formulae to describe the relationship.
File Format
The format in which the data making up a particular 3D object or scene is
stored. File formats come in two types: object formats, such as the LWO
format in LightWave or 3DS format in 3ds max, which contain only details of
the geometry and surface properties of an object; and scene formats, such as
their LWS and MAX equivalents, which contain such global information as
lighting, animation or camera data. Other file formats supported by most
major 3D software packages include the DXF and IGES formats for CAD and
NURBS models, the OBJ object format, and the cross-platform FBX format
developed by Kaydara for the interchange of motion data between 3D
applications.
Flythrough
A type of animation in which the camera moves around a scene, rather than
objects moving in front of a stationary camera.
Frame
A still two-dimensional image. In computer animation, the term ‘frames per
second’ (fps) is a measurement of the number of still frames displayed in one
second to give the impression of a moving image. For film work, this value is
usually 24; for the European PAL broadcast format, 25; and for the US NTSC
broadcast format, 30 fps.

Global Illumination
A superset of the radiosity and raytracing rendering techniques. The goal of
Global Illumination rendering is to compute all of the possible light interactions
between surfaces in a given scene, and thus obtain a truly photorealistic
image. All combinations of diffuse and specular reflections and transmissions
must be accounted for. Effects such as color bleeding and caustics must also
be included in a global illumination simulation.
Group
A set of sub-objects within a model or scene that move and behave as a
single entity, yet can still be split apart (ungrouped), if necessary. Most
complicated models are constructed from several less complex parts that
need to maintain the same spacing and orientation; grouping provides a way
of locking the relative positions of the objects without joining them
permanently.
GUI
Graphical User Interface. An icon-based interface that controls a 3D software
package. Although the GUI varies from program to program, there are certain
basic conventions governing the layout of the main professional 3D
applications.
Hard-Body Dynamics
Also known as rigid-body dynamics, hard-body dynamics simulate the
physical behavior of rigid objects that do not deform upon collision.
Hardware Rendering
Also known as display rendering, hardware rendering previews a 3D scene
within the viewports on a 3D software package, providing real-time on-screen
feedback about the effects of changes made to that scene, but omitting
certain processor-intensive effects such as volumetrics, shadowing and
realistic refraction.
HDRI
High Dynamic Range Image. A 2D image stored in a file format with a greater
range of luminance values than a standard bitmap image. HDR images are
often used as environment maps in image-based lighting techniques to create
subtle, real-world lighting effects.
Hierarchy
The relationship of the sub-objects within a model or a scene to one another.
Sub-objects may exist as parents, children or independents. A parent object
controls the motion of all child objects linked to it, although the motion of a
child object does not affect that of the parent.
History
Image-Based Lighting
Copyright © Bunkspeed, Inc. 2002-2014
A record of the previous values of the attributes of a 3D scene, enabling an
artist to revert immediately to a particular earlier state. The history is
especially valuable during the modelling process.
A technique in which a photographic reference image is used as an
environment map to control the surface illumination of a 3D object, in order to
create subtle real-world lighting effects.

In-betweening
The generation of intermediate transition positions between two keyframes.
The term is drawn from traditional cel animation, where a lead artist generates
the beginning and end keyframes of a sequence (typically one second apart),
a breakdown artist does the breakdowns (typically four frames apart), and an
‘in-betweener’ completes the rest.
Interpolation
The mathematical procedure by which a 3D software package calculates the
in-between positions between two keyframes.
Invisible
A point within a 3D scene that does not render out, but which is used as a
reference for other objects.
Joints
Points of articulation between the bones in a character rig. Put another way, a
joint is a group of parts that can be moved separately from the rest of a model
– with the movement taking place relative to a pivot point.
Keyframe
An image, or set of attributes for a 3D scene, used as a reference point in
animation. The artist usually sets up keyframes manually at significant points
in the action, and the computer calculates the inbetween values automatically.
Layer
A level of an image that can be edited independently of the rest of the image.
Lens
Lens Flare
Light
Look Development
Copyright © Bunkspeed, Inc. 2002-2014
In a real camera, a lens is a curved piece of glass or other transparent
material that focuses light onto the film. Modern 3D software is capable of
simulating a variety of optical distortions created by imperfections in realworld lenses, adding realism to the rendered output.
A bright pattern on an image caused by the reflection and refraction of light
within a camera. Although lens flares are actually artefacts of the
photographic process, many 3D software packages offer artists the
opportunity to add them deliberately in order to increase the realism of
rendered output.
A point or volume that emits light onto a 3D object. Types of light supported
within 3D packages include Point lights, which emit light in all directions from
a single point; Spot lights, which emit light in a cone; Distant or Directional
lights, which emit light rays in parallel, illuminating all surfaces within a scene;
and Area lights, which emit light from two-dimensional surfaces.
The process of developing the look of a 3D scene by compositing separate
render passes together in different permutations.

Material
A set of mathematical attributes that determine the ways in which the surface
of a model to which they are applied reacts to light. These attributes are subdivided into individual channels.
Mask
An area that can be protected and isolated from changes applied to the rest of
the image.
Mesh
The surface geometry of a 3D model, made up of a series of linked geometry
elements such as polygons, patches or NURBS surfaces.
Model
Used as a verb, to model means to build a 3D object. Used as a noun, it
means the 3D object created as the end product of the modelling process. A
variety of different methods are used in 3D modelling, including polygonal,
NURBS, Sub-D and metaball techniques.
Motion Blur
An artefact of real-world cinematography in which the camera’s target object
is moving too quickly for the camera to record accurately, and therefore
appears blurred. Many 3D software packages simulate motion blur as a
rendering effect, in order to increase the realism of 3D images or animation.
Multi-pass rendering
To render out the lighting or surface attributes of a scene as separate images,
with a view to compositing them together later. Multi-pass rendering can be
used simply to speed up the rendering process, or in order to develop the look
of a scene by compositing the different passes together in various
permutations.
Negative Light
A light within a 3D scene that decreases the illumination on a surface instead
of adding to it. Negative lights can be used to remove ‘overspill’ in brightly lit
scenes.
Normal
An imaginary line drawn from the centre of a polygon (or other geometry
object) at right angles to the surface.
NURBS
Non-Uniform Rational B-Splines. NURBS curves are two-dimensional curves
whose shape is determined by a series of control points or CVs between
which they pass. When a series of such curves are joined together, they form
a three-dimensional NURBS surface. Such surfaces have a separate coordinate space (known as UV co-ordinate space) to that of the 3D scene in
which they are situated. NURBS are commonly used to model organic
curved-surface objects.

Particle System
An animation system consisting of a large number of very small points whose
behavior is determined mathematically. A particle system typically consists of
an emitter (which may be a point, surface or volume, and may emit particles
directionally or in all directions) and a series of fields that determine the
motion of those particles. Individual particles have a finite lifespan, and may
possess attributes (such as color, radius, and opacity) that vary over the
course of that lifespan. Particle effects are commonly used to simulate fire,
smoke, steam and other fluids, or to control complex animations such as
crowd scenes.
Plane
A two-dimensional surface in Cartesian co-ordinate space. Essentially a flat
sheet extending infinitely in all directions, a plane may be used to aid object
manipulation, positioning and construction, and is not usually made visible in
a final render.
Plugin
A small piece of third-party software that is loaded into a 3D application in
order to extend its functionality. Plugins commonly perform such specialist
tasks as file conversion or data export, texture generation, and physics or fluid
simulation. There are thousands of plugins currently available on the Internet,
both commercially and as free downloads.
Point
A one-dimensional point in coordinate space. Points can be linked up to form
polygons, used as control vertices for NURBS curves, or employed as nulls to
control lights or cameras, amongst other functions.
Polygon
A geometry element formed by connecting three or more points. A triangle, or
three-point polygon, is the simplest form of polygonal geometry. Polygonal
modelling is a fast, intuitive method of creating 3D objects, but does not easily
generate smooth curved surfaces.
Post Processing
The manipulation of a rendered image, either to improve the quality of that
image, or to create effects that cannot easily be achieved directly within the
3D software itself. Some 3D software packages can be set to automatically
apply post-processing effects, such as motion blur or Depth of Field, after a
frame is rendered.
Preset
A pre-generated list of settings for a particular 3D software package. Presets
are usually used to control and customise properties such as rendering or
lighting styles. Like plugins, they may either be commercial products, or freely
downloadable from the Internet.
Preview
A time-saving method of checking the progress of a project by rendering it at
a lower quality, resolution or frame rate than will be used for the final project.

Reflection Map
Appendix
Glossary
A simple three-dimensional form used as the basis for constructive solid
geometry modelling techniques. Typical primitives include the plane, the
cube, the sphere, the cone and the torus.
A texture map that is generated by a mathematical function, rather than a
real-world bitmap image projected over the surface of an object.
The process by which a two-dimensional texture map is applied over the
surface of a three-dimensional object, as if it were an image projected from a
slide projector. There are several common projection types, including Planar,
Cubic, Spherical and Cylindrical. Which one is most appropriate depends on
the type of map being projected, and the shape of the object it is being
projected upon.
A technique for rendering 3D scenes. Radiosity simulates the way in which
light bounces from surface to surface within a scene, and is more accurate,
but also more processor-intensive, than raytracing.
A technique for rendering 3D scenes. Raytracing traces the path of every ray
of light from its source until it either leaves the scene or becomes too weak to
have an effect. The term is also sometimes applied to the reverse method:
tracing the path of every ray of light from the camera backwards to the light
source.
An environment map used to simulate real-world reflection effects on the
surface of a 3D object. Reflection maps render more quickly than methods
that generate true surface reflections, such as raytracing.
Rendering
The process of converting the 3D data stored in a software package into the
two-dimensional image ‘seen’ by the camera within the scene. Rendering
brings together the scene geometry, Z-depth, surface properties, lighting setup and rendering method to create a finished frame. Rendering comes in two
forms: Display or Hardware rendering, used to display the scene on-screen in
the software package’s viewports; and the more processor intensive Finalquality or Software rendering, which generates an image for output, and takes
account of properties that Display rendering overlooks, such as shadows,
reflections and post-process effects.
Resolution
The size of the final image in pixels when rendering out a scene. Higher
resolution renders contain more detail, but take longer to complete.
Scene
A set of 3D objects, including the models themselves and the lights and
camera that will be used when rendering them out.

Shading
Snapping
Appendix
Glossary
The mathematical process of calculating how a model’s surfaces react to
light. A variety of alternative algorithms can be used for the task, including
Phong, Lambert, and Blinn shading models. Shaders are often built up as
node-based shading trees, with each node controlling a specific aspect of the
process.
The automatic alignment of one object to another or to a reference grid,
intended to aid the precise placement of objects within a scene or modelling
hierarchy.
Specularity
A surface property of an object that determines the way in which highlights
appear on that surface.
Symmetry
A modelling option in which any changes made to the model are duplicated
across an axis of reflectional symmetry. This makes it possible to create
complex symmetrical objects, such as a human or animal head, without
having to work directly on more than one half of the model.
Texture
Three-Point Lighting
A bitmap image that is applied to the surface of 3D object to give it detail.
Texture maps may be either photographic images or procedural textures, and
may be applied in each of the material channels of an object using a variety of
mapping or projection methods.
A system of CG lighting derived from real-world cinematography, in which a
scene is illuminated by three light sources: a Key light, which acts as the
primary source of illumination for the scene; a Fill light, which illuminates
shadow areas; and a Rim light, which illuminates the edges of objects and
helps them stand out from the background.
Tiling
The process of duplicating a texture across the surface of an object. Tiling
textures must be created so that the edge of one aligns perfectly with that of
its neighbor, otherwise the result is a series of ugly seams. High frequency
textures are those in which patterns repeat at short intervals over an object’s
surface; low-frequency textures are those in which the intervals are larger.
Timeline
A fundamental element of the graphical user interface of most modern 3D
software packages which shows the timing of the keyframes in a sequence of
animation. Playback of the animation may be controlled either by a series of
VCR-like controls, or by clicking and dragging with the mouse to ‘scrub’ a
slider to and fro along the timeline.
UV Texture Coordinates
Copyright © Bunkspeed, Inc. 2002-2014
The co-ordinate system used for assigning textures to polygonal models.
Since UV co-ordinate space is two-dimensional, one of several projection
methods must be used to ‘unwrap’ the UVs from the model and lay them flat
on a plane. Once unwrapped, the UV map may be screen grabbed and
exported to a paint package for texture painting.

See: Point.
The region of the interface of a 3D software package in which the scene is
displayed to the artist.
A shading method in which a simple grid of lines is used to represent the
basic contours of the underlying model. For many 3D artists, this is a favoured
mode to work in, since it permits them to see faces and surfaces that would
otherwise be hidden by overlying geometry.
See: Co-ordinate systems.
The distance a particular point or surface lies inside a scene. Z-depth
information is used to calculate where a light casts shadows, and also to
calculate which surfaces are visible to the camera during rendering, and
which are obscured by nearer geometry.
