CGAL::Parameterization_mesh_feature_extractor< ParameterizationMesh_3 > Class Template Reference
Helper Class

#include <CGAL/Parameterization_mesh_feature_extractor.h>

Definition

The class Parameterization_mesh_feature_extractor computes features (genus, borders, ...) of a 3D surface, model of the ParameterizationMesh_3 concept.

Examples:
Surface_mesh_parameterization/Complete_parameterization_example.cpp, Surface_mesh_parameterization/Mesh_cutting_parameterization.cpp, and Surface_mesh_parameterization/polyhedron_ex_parameterization.cpp.

Public Types

typedef ParameterizationMesh_3 Adaptor
 Export ParameterizationMesh_3 template parameter.
 
typedef std::list< typename
Adaptor::Vertex_handle > 		Border
 Type representing a border = STL container of vertex handles.
 
typedef std::vector< Border * > Skeleton
 Type representing the list of all borders of the mesh = STL container of Border elements. More...

typedef std::vector<Border*> CGAL::Parameterization_mesh_feature_extractor< ParameterizationMesh_3 >::Skeleton

Type representing the list of all borders of the mesh = STL container of Border elements.

template<class ParameterizationMesh_3 >
CGAL::Parameterization_mesh_feature_extractor< ParameterizationMesh_3 >::Parameterization_mesh_feature_extractor ( Adaptor &  mesh)

Constructor.

Attention
This class caches the result of feature extractions => The caller must not modify mesh during the Parameterization_mesh_feature_extractor life cycle.

template<class ParameterizationMesh_3 >
const Skeleton& CGAL::Parameterization_mesh_feature_extractor< ParameterizationMesh_3 >::get_borders ( )

Get extracted borders.

The longest border is the first one.
