RNormal Class Reference

#include <mesh.h>

Class Description

The 'rendered' normal class. RNormals are stored as unit vectors in object space. An instance of this class is maintained by the RVertex class since the RVertex is what gets rendered (lit), and the lighting methods need to know about the normals. All methods of this class are implemented by the system. Note:This class is used internally by 3ds Max. Developers who need to compute face and vertex normals for a mesh should instead refer to the Advanced Topics section "Computing Face and Vertex Normals".
