template<class PointRange, class TriangleRange, typename Creator = Creator_uniform_3< typename Kernel_traits< typename PointRange::value_type >::Kernel::RT, typename PointRange::value_type>>
struct CGAL::Random_points_in_triangle_soup_3< PointRange, TriangleRange, Creator >

The class Random_points_in_triangle_soup_3 is an input iterator creating points uniformly distributed inside a soup of triangles.

The triangle range must be valid and unchanged while the generator is used. Triangle are triple of indices refering to position of points in the input point range.

Template Parameters

PointRange	a model of the concepts `RandomAccessContainer` with value type begin a point from a CGAL kernel
TriangleRange	a model of the concept `RandomAccessContainer`, with `value_type` being a model of `RandomAccessContainer` with `std::size_t` as `value_type`.

Is model of: InputIterator
: PointGenerator

Functions
	Random_points_in_triangle_soup_3 (const PointRange &points, const TriangleRange &triangles, 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, std::size_t >	point_and_support () const
	returns the last point generated and the id in the input range of the triangle used to generate that point.

template<class PointRange , class TriangleRange , typename Creator = Creator_uniform_3< typename Kernel_traits< typename PointRange::value_type >::Kernel::RT, typename PointRange::value_type>>

CGAL::Random_points_in_triangle_soup_3< PointRange, TriangleRange, Creator >::Random_points_in_triangle_soup_3	(	const PointRange &	points,
		const TriangleRange &	triangles,
		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.
