The data can define concave or intersecting polygons. However, if the edges of an individual Patch face intersect themselves, the resulting face may or may not be completely filled. In the 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.
