data FaceIndex

A face index is a triplet of indices. FaceIndex vi vti vni is a face that indexes the locations with vi, the texture coordinates with vti and the normals with vni. An index set to Nothing means no information. That is, if vni == Nothing, then that FaceIndex doesn’t have a normal associated with.
