Usage
member(whichCastmember).modelResource(whichModelResource).\
face[faceIndex].colors
Description
3D face property; a linear list of three integers indicating which index positions of the model
resource’s color list to use for the three vertices of the face. The color list is a linear list of
rgb
values.
The
colors property is used only with model resources whose type is #mesh.
You must use the model resource’s
build() command after setting this property; otherwise, the
changes will not take effect.
Example
This example creates a model resource whose type is #mesh, specifies its properties, and then
creates a new model with it.
Line 1 uses the
newMesh() command to create a #mesh model resource named Triangle, which
has one face, three vertices, and a maximum of three colors. The number of normals and the
number of texture coordinates are not set.
Line 2 sets the
vertexList property to a list of three vectors.
Line 3 assigns the vectors of the
vertexList property to the vertices of the first face of Triangle.
Line 4 sets the color list to three
rgb values.
Line 5 assigns colors to the first face of Triangle. The third color in the color list is applied to the
first vertex of Triangle, the second color to the second vertex, and the first color to the third
vertex. The colors will spread across the first face of Triangle in gradients.
Line 6 creates the normals of Triangle with the
generateNormals() command.
Line 7 uses the
build() command to construct the mesh.
Line 8 creates a new model named TriModel that uses the new mesh.
