template<class GeomKernelT >
void OpenVolumeMesh::NormalAttrib< GeomKernelT >::update_face_normals ( )

Compute face normals.

This is accomplished by taking two adjacent half-edges that are incident to the faces and compute their cross product. Note that this method looses accuracy in case the faces in question is not planar.

template<class GeomKernelT >
void OpenVolumeMesh::NormalAttrib< GeomKernelT >::update_vertex_normals ( )

A simple heuristic to estimate the vertex normals.

This function takes the vertices' surrounding outside face normals into account and computes an average out of it.
