#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

Member Typedef Documentation

template<class ParameterizationMesh_3 >

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.
