5.1 Face & Edge Colors

Face colors are used for all 3D surfaces (solid graphics mode only) whereas edge colors are used for lines and wireframe graphics (both solid and wireframe graphics mode).

These fields are ignored if cell flag bit 4 is set; in this case, face and edge colors are inherited from the parent set. If the root set inherits from its parent, then the color is assigned elsewhere in AutoMod. For example, a vehicle may be assigned a color in a movement system; it's cell file's root set then inherits this color.

The color is encoded as a decimal integer value, whose meaning should be interpreted as follows:

Code	Color
0	Black
1	Red
2	Green
3	Yellow
4	Blue
5	Magenta
6	Cyan
7	White
8	Light Gray
9	Dark Gray
10	Brown
11	Light Blue
12	Purple
13	Orange
14	Light Green
15	Light Yellow

Note that, as of V8.5, AutoMod allows the RGB (red-green-blue) settings for each color to be specified in the .asilibrc settings file. It is possible, for example, to change color 1 so that it appears blue, yellow, or some custom color. To accurately reproduce the content of a cell file's appearance, the .asilibrc file - if present - should also be processed; the format of this file is currently beyond the scope of this document. Also note that the .asilibrc file permits more than 16 colors to be defined; however, AutoMod does not appear to support colors with numbers outside the range of 0-15.

As of V10.0, AutoMod only uses the face color; edge colors are not supported by the OpenInventor scene graph and are ignored.

The default face and edge color is red (1).
