#include <CGAL/Polyhedral_mesh_domain_with_features_3.h>

Inherits from

Definition

The class Polyhedral_mesh_domain_with_features_3 implements a domain whose boundary is a simplicial polyhedral surface.

This surface must be free of intersection. It must also be either closed or included inside another polyhedral surface which is closed and free of intersection.

It is a model of the concept MeshDomainWithFeatures_3. It also provides a member function to automatically detect sharp features from the input polyhedral surface(s).

Template Parameters
IGTstands for a geometric traits class providing the types and functors required to implement the intersection tests and intersection computations for polyhedral boundary surfaces. This parameter has to be instantiated with a model of the concept IntersectionGeometricTraits_3.
Is Model Of:

Constructor & Destructor Documentation

template<typename IGT >
template<typename Polyhedron >
CGAL::Polyhedral_mesh_domain_with_features_3< IGT >::Polyhedral_mesh_domain_with_features_3 ( Polyhedron  bounding_polyhedron)

Constructs a Polyhedral_mesh_domain_with_features_3 from a polyhedral surface of type Polyhedron.

The only requirement on type Polyhedron is that CGAL::Mesh_polyhedron_3<IGT>::type should be constructible from Polyhedron. No feature detection is done at this level. Note that a copy of bounding_polyhedron will be done. The interior of bounding_polyhedron will be meshed.

template<typename IGT >
CGAL::Polyhedral_mesh_domain_with_features_3< IGT >::Polyhedral_mesh_domain_with_features_3 ( const std::string &  filename)

Constructs a Polyhedral_mesh_domain_with_features_3 from an off file.

No feature detection is done at this level.

template<typename IGT >
template<typename Polyhedron >
CGAL::Polyhedral_mesh_domain_with_features_3< IGT >::Polyhedral_mesh_domain_with_features_3 ( Polyhedron  polyhedron,
Polyhedron  bounding_polyhedron 
)

Constructs a Polyhedral_mesh_domain_with_features_3 a polyhedral surface, and a bounding polyhedral surface,.

CGAL::Mesh_polyhedron_3<IGT>::type should be constructible from Polyhedron. The first polyhedron should be entirely included inside bounding_polyhedron, which has to be closed and free of intersections. Using this constructor allows to mesh a polyhedral surface which is not closed, or has holes. The inside of bounding_polyhedron will be meshed.

Member Function Documentation

template<typename IGT >
void CGAL::Polyhedral_mesh_domain_with_features_3< IGT >::detect_features ( FT  angle_bound = 120)

Detects sharp features of the internal bounding polyhedron (and the potential internal polyhedron) and inserts them in as features of the domain.

angle_bound gives the maximum dihedral angle (in degrees) between two triangles of the input polyhedron/a which is used to consider that the edge between those triangles is a feature edge.
