CGAL::Mesh_constant_domain_field_3< Gt, Index_ > Class Template Reference

#include <CGAL/Mesh_constant_domain_field_3.h>

Definition

The class Mesh_constant_domain_field_3 is a model of concept MeshDomainField_3.

It provides a constant field accessible using queries on 3D-points.

The class Mesh_constant_domain_field_3 can also be customized through set_size() operations to become a piecewise constant field, i.e. a sizing field with a constant size on each subpart of the domain.

Template Parameters

Gt	is the geometric traits class. It must match the type Triangulation::Geom_traits, where Triangulation is the nested type of the model of MeshComplex_3InTriangulation_3 used in the meshing process.
Index_	is the type of index of the vertices of the triangulation. It must match the type Index of the model of MeshDomain_3 used in the meshing process.

Is Model Of:

MeshDomainField_3

Examples:

Mesh_3/mesh_3D_image_variable_size.cpp.

Types
typedef Gt::FT	FT
	Numerical type.
typedef Gt::Point_3	Point_3
	Point type.
typedef Index_	Index
	Type of index of the vertices of the triangulation.

Creation
	Mesh_constant_domain_field_3 (const FT &size)
	Builds a constant domain field with size size.

Operations
FT	operator() (const Point_3 &, const int dim, const Index &index) const
	Returns the size of query points of dimension dim and index index.
void	set_size (const FT &size, const int dim, const Index &index)
	Sets the size such that operator() for any query point of dimension dim and index index returns size.
