Patch Normals

Calculates the normal vectors of a triangulated mesh (patch)

This function calculates the normal vectors of a triangulated mesh such as used by the Matlab function patch.

It first calculates the normal vectors of all faces, and after that calculates the vertex normals from the face normals weighted by the angles of the faces.

The function is both implemented as a normal Matlab function and as a mex file in c-code (much faster)
