CGAL::Random_points_in_tetrahedral_mesh_3< C3T3, Creator > Class Template Reference

`#include <CGAL/point_generators_3.h>`

## Definition

template<class C3T3, class Creator = Creator_uniform_3< typename Kernel_traits< typename C3t3::Point >::Kernel::RT, typename C3t3::Point >>
class CGAL::Random_points_in_tetrahedral_mesh_3< C3T3, Creator >

The class `Random_points_in_tetrahedral_mesh_3` is an input iterator creating points uniformly distributed inside a tetrahedral mesh of type `Mesh_complex_3_in_triangulation_3`.

The tetrahedral mesh must be valid and unchanged while the iterator is used.

Template Parameters

  C3T3 | must be a model of `Mesh_complex_3_in_triangulation_3`

Is model of
  `InputIterator`
  `PointGenerator`

## Constructor & Destructor Documentation

## ◆ Random_points_in_tetrahedral_mesh_3()

template<class C3T3 , class Creator = Creator_uniform_3< typename Kernel_traits< typename C3t3::Point >::Kernel::RT, typename C3t3::Point >>

CGAL::Random_points_in_tetrahedral_mesh_3< C3T3, Creator >::Random_points_in_tetrahedral_mesh_3 | ( | const C3T3 & | c3t3,
|  | Random & | rnd = `get_default_random()`
| ) |  |

Creates an input iterator `g` generating points of type `Weighted_point_3` uniformly distributed inside the tetrahedra of the mesh.

Each tetrahedron has a probability to be chosen to hold the point depending on its volume.
