## Definition

template<typename Point_2, typename Triangulation, typename Creator = Creator_uniform_2<typename Kernel_traits<Point_2>::Kernel::RT,Point_2>>
class CGAL::Random_points_in_triangle_mesh_2< Point_2, Triangulation, Creator >

The class `Random_points_in_triangle_mesh_2` is an input iterator creating points uniformly distributed inside a 2D domain represented by a 2D triangulation.

Triangulation must be a CGAL triangulation with a face model of `DelaunayMeshFaceBase_2`. The sampled model is the union of the faces for which `DelaunayMeshFaceBase_2::is_in_domain()` returns `true`. The triangulation must be valid and unchanged while the iterator is used.

Is model of
  `InputIterator`
  `PointGenerator`

## Functions
| Random_points_in_triangle_mesh_2 (const Triangulation &triangulation, Random &rnd=get_default_random())
| creates an input iterator `g` generating points of type `Point_2` uniformly distributed between the triangles of the triangulation.
std::pair< Point_2, typename Triangulation::Face_handle > | point_and_support () const
| returns the last point generated and a handle of the face used to generate that point.

## ◆ Random_points_in_triangle_mesh_2()

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

CGAL::Random_points_in_triangle_mesh_2< Point_2, Triangulation, Creator >::Random_points_in_triangle_mesh_2 | ( | const Triangulation & | triangulation,
|  | Random & | rnd = `get_default_random()`
| ) |  |

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

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