Definition

template<typename Point_2, typename Triangle_2 = typename Kernel_traits<Point_2>::Kernel::Triangle_2, typename Creator = Creator_uniform_2<typename Kernel_traits<Point_2>::Kernel::RT,Point_2>>
struct CGAL::Random_points_in_triangles_2< Point_2, Triangle_2, Creator >

The class Random_points_in_triangles_2 is an input iterator creating points uniformly distributed inside a range of Triangle_2.

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

Is model of

InputIterator

Functions
template<typename TriangleRange>
	Random_points_in_triangles_2 (const TriangleRange &triangles, Random &rnd=get_default_random())
	creates an input iterator g generating points of type Point_2 uniformly distributed between the triangles of the range.
std::pair< Point_2, const Triangle_2 * >	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_2()

template<typename Point_2, typename Triangle_2 = typename Kernel_traits<Point_2>::Kernel::Triangle_2, typename Creator = Creator_uniform_2<typename Kernel_traits<Point_2>::Kernel::RT,Point_2>>

template<typename TriangleRange>

CGAL::Random_points_in_triangles_2< Point_2, Triangle_2, Creator >::Random_points_in_triangles_2	(	const TriangleRange &	triangles,
		Random &	rnd = get_default_random() )

creates an input iterator g generating points of type Point_2 uniformly distributed between the triangles of the range.

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