Definition

template<typename Point_3, typename Triangle_3 = typename Kernel_traits<Point_3>::Kernel::Triangle_3, typename Creator = Creator_uniform_3< typename Kernel_traits< Point_3 >::Kernel::RT, Point_3 >>
struct CGAL::Random_points_in_triangles_3< Point_3, Triangle_3, Creator >

The class Random_points_in_triangles_3 is an input iterator creating points uniformly distributed inside a range of Triangle_3.

The triangle range must be valid and unchanged while the generator is used.

Is model of

InputIterator

	Random_points_in_triangles_3 (const TriangleRange &triangulation, Random &rnd=get_default_random())
	creates an input iterator g generating points of type Point_3 uniformly distributed between the triangles of the range.
std::pair< Point_3, const Triangle_3 * >	point_and_support () const
	returns the last point generated and a pointer to the input triangle used to generate that point.

Constructor & Destructor Documentation

Random_points_in_triangles_3()

template<typename Point_3, typename Triangle_3 = typename Kernel_traits<Point_3>::Kernel::Triangle_3, typename Creator = Creator_uniform_3< typename Kernel_traits< Point_3 >::Kernel::RT, Point_3 >>

template<typename TriangleRange>

CGAL::Random_points_in_triangles_3< Point_3, Triangle_3, Creator >::Random_points_in_triangles_3	(	const TriangleRange &	triangulation,
		Random &	rnd = get_default_random() )

creates an input iterator g generating points of type Point_3 uniformly distributed between the triangles of the range.

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