#include <CGAL/Mesh_3/Construct_initial_points_gray_image.h>

Definition

template<typename C3t3, typename MeshDomain, typename Functor = CGAL::Null_functor>
struct CGAL::Construct_initial_points_gray_image< C3t3, MeshDomain, Functor >

Functor for generating initial points in gray images.

This functor is a model of the InitialPointsGenerator concept, and can be passed as a parameter to CGAL::make_mesh_3 using the CGAL::parameters::initial_points_generator() parameter function.

On images that contain multiple non-connected components, this functor will scan the full image and output points on every component.

Is model of

InitialPointsGenerator

	constructs at least n points by collecting them on the surface of all objects in the image, even if they are non-connected components.

template<typename OutputIterator >

OutputIterator CGAL::Construct_initial_points_gray_image< C3t3, MeshDomain, Functor >::operator()	(	OutputIterator	pts,
		int	n = 20
	)		const

constructs at least n points by collecting them on the surface of all objects in the image, even if they are non-connected components.

Using this functor guarantees to initialize each connected component.

Template Parameters
