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
C3T3must be a model of Mesh_complex_3_in_triangulation_3
Is Model Of:

InputIterator

PointGenerator

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.
