Definition at line 69 of file NormalAttrib.hh.

◆ update_face_normals()

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.

Definition at line 76 of file NormalAttribT_impl.hh.

◆ update_vertex_normals()

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.
