CGAL::Mesh_cell_criteria_3< Tr > Class Template Reference

#include <CGAL/Mesh_cell_criteria_3.h>

Definition

template<typename Tr>
class CGAL::Mesh_cell_criteria_3< Tr >

The class Mesh_cell_criteria_3 is a model of MeshCellCriteria_3.

It provides, for the mesh tetrahedra, a uniform shape criterion and a sizing field which may be a uniform or variable field.

Template Parameters

Tr	must be identical to the nested type Triangulation of the instance used as model of MeshComplex_3InTriangulation_3.

Is model of

MeshCellCriteria_3

Public Member Functions
Is_cell_bad	operator() (const Tr &tr, const Cell_handle &cell) const
	returns whether the cell cell is bad or not.

Types
typedef Tr::Geom_traits::FT	FT
	Numerical type.

Creation
	Mesh_cell_criteria_3 (const FT &radius_edge_bound, const FT &radius_bound, const FT &min_radius_bound=0.)
	Returns an object to serve as default criteria for cells.
template<typename Sizing_field >
	Mesh_cell_criteria_3 (const FT &radius_edge_bound, const Sizing_field &radius_bound, const FT &min_radius_bound=0.)
	Returns an object to serve as default criteria for facets.

Constructor & Destructor Documentation

Mesh_cell_criteria_3() [1/2]

template<typename Tr >

CGAL::Mesh_cell_criteria_3< Tr >::Mesh_cell_criteria_3	(	const FT &	radius_edge_bound,
		const FT &	radius_bound,
		const FT &	min_radius_bound = 0.
	)

Returns an object to serve as default criteria for cells.

Parameters

radius_edge_bound	is the upper bound for the radius-edge ratio of the tetrahedra.
radius_bound	is a uniform upper bound for the circumradii of the tetrahedra in the mesh
min_radius_bound	is a uniform lower bound for the circumradii of the tetrahedra in the mesh. Only cells with a circumradius larger than that bound will be refined.

See Section introsecparam for further details. Note that if one parameter is set to 0, then its corresponding criterion is ignored.

Mesh_cell_criteria_3() [2/2]

template<typename Tr >

template<typename Sizing_field >

CGAL::Mesh_cell_criteria_3< Tr >::Mesh_cell_criteria_3	(	const FT &	radius_edge_bound,
		const Sizing_field &	radius_bound,
		const FT &	min_radius_bound = 0.
	)

Returns an object to serve as default criteria for facets.

Template Parameters

SizingField

must be a model of the concept MeshDomainField_3.

The behavior and semantic of the arguments are the same as above, except that the radius bound parameter is a functional instead of a constant.
