Triangle primitive for building a 3-D shape.

MeshGeometry3D allows the developer to specify position, normal, and texture coordinate information. The Positions property is required.

Normals are assumed to be associated with the front faces of a mesh primitive. The winding order (the order in which the Positions that make up each triangle of the mesh are specified) determines whether a given face is front-facing or back-facing. Front-facing triangles are wound in counter-clockwise order; back-facing triangles are wound in clockwise order.
