Plane Planar mapping applies the diffuse map without distorting the front plane of the 3D model, similar to a movie pro-
jector casting an image onto a screen. All 3D coordinates of the geometry are mapped to this plane to generate the diffuse
values. Planar mapping positions the lower-left corner of the diffuse map on the 3D model’s axis. When you apply planar
mapping, any surfaces on the 3D model perpendicular to the front plane cause the pixels at the edge of the texture to project
along the “sides” of the object.
Perspective Perspective mapping is similar to planar mapping, except that it performs a perspective transformation of the
diffuse map based on the selected camera’s field of view (FOV). When you select Perspective as the mapping type, the Per-
spective Camera box becomes active, allowing you to specify the active camera. The FOV of the camera has an impact on
the resulting effect of any transform applied to the parent axis of the texture. On stereo cameras, the interaxial distance
between left and right cameras also has an effect on the resulting perspective transform.
Camera box Specify which camera's FOV to take into account when using perspective mapping.
Camera field Displays the active perspective camera number. Non-editable.
Filter box Select the type of filtering to apply to the diffuse map.
To apply:Select:
No filtering — the pixel of the texture closest to the screen pixel is displayed.Nearest
Basic bilinear filtering.Linear
Non-proportional filtering between X and Y (faster to process than EWA, but with
a lesser quality).
Anisotropic
A combination of Anisotropic and Linear filtering.Aniso+Linear
A high-quality elliptical weighted average filter to produce enhanced rendering
results (slower to process than other filters).
EWA
A combination of EWA and Linear filtering (offers the most advanced filter pro-
cessing).
EWA+Linear
TIP You can set the default filtering type in the Action Setup menu Preferences tab.
Camera Type box Select the camera type visibility for the map. For example, you can use this setting to
apply a Left Eye and Right Eye camera type for two maps that are children of the same surface or geometry
in a stereo scene.
Texture Name field Displays the name of an externally loaded diffuse map texture. Non-editable.
