The class Random_points_in_triangle_mesh_3 is an input iterator creating points uniformly distributed inside the faces of a triangle mesh model of FaceListGraph.

The triangle mesh must be valid and unchanged while the iterator is used.

Is Model Of:

InputIterator

PointGenerator

	Random_points_in_triangle_mesh_3 (const TriangleMesh &mesh, VertexPointMap vpm, Random &rnd=get_default_random())
	Creates an input iterator `g` generating points of type `Point_3` uniformly distributed in the mesh faces based on `vpm`. More...

	Random_points_in_triangle_mesh_3 (const TriangleMesh &mesh, Random &rnd=get_default_random())
	Similar to the previous constructor using `get(vertex_point, mesh)` as vertex point map.

CGAL::Random_points_in_triangle_mesh_3< TriangleMesh, VertexPointMap, Creator >::Random_points_in_triangle_mesh_3	(	const TriangleMesh &	mesh,
		VertexPointMap	vpm,
		Random &	rnd = `get_default_random()`
	)

Creates an input iterator g generating points of type Point_3 uniformly distributed in the mesh faces based on vpm.

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