CGAL 4.3 - Approximation of Ridges and Umbilics on Triangulated Surface Meshes
|
#include <CGAL/Ridges.h>
The class Ridge_approximation
computes the approximation of ridges of a triangular polyhedral surface.
TriangulatedSurfaceMesh | is the surface type. |
Vertex2FTPropertyMap,Vertex2VectorPropertyMap | provide the differential properties of the surface associated to its vertices. |
Requirements (checked at compile time):
TriangulatedSurfaceMesh::Traits::FT
and Vertex2FTPropertyMap::value_type
must coincide;TriangulatedSurfaceMesh::Traits::Vector_3
and Vertex2VectorPropertyMap::value_type
must coincide;TriangulatedSurfaceMesh::Vertex_handle
, Vertex2FTPropertyMap::key_type
and Vertex2VectorPropertyMap::key_type
must coincide;Ridge_line

The two last property maps may not be used if computations are performed with the parameter Tag_3 , in which case these property maps shall be initialized with their default constructors. | |
