Approximation of Ridges and Umbilics on Triangulated Surface Meshes Reference

#include <CGAL/Umbilics.h>

Definition

The class Umbilic_approximation computes the approximation of umbilics on a triangular polyhedral surface.

Template Parameters
TriangulatedSurfaceMeshis the surface type.
Vertex2FTPropertyMap,Vertex2VectorPropertyMapprovide the differential properties of the surface associated to its vertices.

Requirements (checked at compile time) :

  • the types TriangulatedSurfaceMesh::Traits::FT and Vertex2FTPropertyMap::value_type must coincide;
  • the types TriangulatedSurfaceMesh::Traits::Vector_3 and Vertex2VectorPropertyMap::value_type must coincide;
  • the types TriangulatedSurfaceMesh::Vertex_handle, Vertex2FTPropertyMap::key_type and Vertex2VectorPropertyMap::key_type must coincide;

Performs the approximation, size determines the size of the patches around vertices, taken as size times the size of the 1-ring.

Umbilics are inserted into the OutputIterator it with value type Umbilic*.
