Approximation of Ridges and Umbilics on Triangulated Surface Meshes Reference

#include <CGAL/Ridges.h>

Definition

The class Ridge_line stores the description of a ridge line.

The list of halfedges defines a connected sequence of edges (but not as oriented halfedges). The scalar b paired with a halfedge pq is the barycentric coordinate of the crossing point r with the ridge: r=b×p+(1−b)×q.
