Description:
For primitive based mappings, these transformations are used to map the world coordinate (x,y,z) point P and surface normal N before it is projected to the normalized mapping primitive. The surface normal transformation, m_Nxyz, is always calculated from m_Pxyz. It is a runtime setting that is not saved in 3dm files. If m_type is srfp_mapping, then m_Pxyz and m_Nxyz are ignored.
