CGAL::Random_points_in_triangles_3< Point_3, Triangle_3, Creator > Struct Template Reference

`#include <CGAL/point_generators_3.h>`

## 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`
  `PointGenerator`

## Functions
template<typename TriangleRange >
| 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.

## ◆ 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.
