In that case, it is better to break up the face into smaller polygons. See the CData and FaceVertexCData property descriptions for information on how to specify color. Edges can be only a single color. Edges can be only a single color. Edges can be flat or interpolated.
Edges can be only a single color.
Edges can be only a single color. Edges can be flat or interpolated. The first approach specifies the coordinates of each vertex. In this example, the coordinate data defines two triangular faces, each having three vertices. Using true color, the top face is set to white and the bottom face to gray.
