InitialPointsGenerator Concept Reference

Definition

The function object concept InitialPointsGenerator is designed to construct a set of initial points on the surface of the domain.

Has models

CGAL::Construct_initial_points_labeled_image

CGAL::Construct_initial_points_gray_image

Types
typedef unspecified_type	MeshDomain
	Mesh domain type to be meshed, model of MeshDomain_3
typedef unspecified_type	C3t3
	Type of the output mesh complex, model of MeshComplex_3InTriangulation_3

Operations
template<typename OutputIterator >
OutputIterator	operator() (OutputIterator pts, int n)
	Outputs a set of surface points, for mesh initialization, to the output iterator pts.
template<typename OutputIterator >
OutputIterator	operator() (OutputIterator pts)
	Same as above, without the n parameter.

Member Function Documentation

operator()() [1/2]

template<typename OutputIterator >

OutputIterator InitialPointsGenerator::operator()

(

OutputIterator

pts

)

Same as above, without the n parameter.

Since there is no n given like above, the functor must provide enough points to initialize the mesh generation process.

Template Parameters

OutputIterator

model of OutputIterator, containing tuple-like objects made of 3 elements : a C3t3::Triangulation::Point : the point p, a int : the minimal dimension of the subcomplexes to which p belongs, a MeshDomain_3::Index : the index of the corresponding subcomplex.

operator()() [2/2]

template<typename OutputIterator >

OutputIterator InitialPointsGenerator::operator()	(	OutputIterator	pts,
		int	n
	)

Outputs a set of surface points, for mesh initialization, to the output iterator pts.

Template Parameters

OutputIterator

model of OutputIterator, containing tuple-like objects made of 3 elements : a C3t3::Triangulation::Point : the point p, a int : the minimal dimension of the subcomplexes on which p lies, a MeshDomain_3::Index : the index of the corresponding subcomplex.

Parameters

pts	the output points
n	a lower bound on the number of points to construct for initialization. A generator can choose to ignore this parameter. If this operator does not output enough points, then more points will be added automatically by the mesher.
