CGAL 5.1.2 - Approximation of Ridges and Umbilics on Triangulated Surface Meshes
|
#include <CGAL/Ridges.h>
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: \( r = b\times p + (1-b)\times q\).
