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 iterator is used.

Is model of

InputIterator

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	(	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.

const

returns the address of an input triangle containing the last point generated.

Precondition

a point must have been generated before calling the function
