Remarks
For a triangle in a given 3-D mesh, the order in which the triangle's vertex positions are specified determines whether the triangle face is a front or back face.
The Windows Presentation Foundation 3-D implementation uses a counter-clockwise winding order; that is, the points that determine a front-facing mesh triangle's positions should be specified in counterclockwise order, as viewed from the front of the mesh.
Setting the TriangleIndices property is optional. If the indices are not specified, triangles are drawn in a non-indexed fashion. Every set of three positions becomes a triangle.
