#include <CGAL/point_generators_2.h>

Definition

template<typename Point_2, typename Triangulation, typename Creator = Creator_uniform_2<typename Kernel_traits<Point_2>::Kernel::RT,Point_2>>
class CGAL::Random_points_in_triangle_mesh_2< Point_2, Triangulation, Creator >

The class Random_points_in_triangle_mesh_2 is an input iterator creating points uniformly distributed inside a 2D domain represented by a 2D triangulation.

Triangulation must be a CGAL triangulation with a face model of DelaunayMeshFaceBase_2. The sampled model is the union of the faces for which DelaunayMeshFaceBase_2::is_in_domain() returns true. The triangulation must be valid and unchanged while the iterator is used.

Is model of

Random_points_in_triangle_mesh_2()

template<typename Point_2 , typename Triangulation , typename Creator = Creator_uniform_2<typename Kernel_traits<Point_2>::Kernel::RT,Point_2>>

CGAL::Random_points_in_triangle_mesh_2< Point_2, Triangulation, Creator >::Random_points_in_triangle_mesh_2	(	const Triangulation &	triangulation,
		Random &	rnd = get_default_random()
	)

Creates an input iterator g generating points of type Point_2 uniformly distributed between the triangles of the triangulation.

Each triangle has a probability to be chosen to hold the point depending on its area.
