CGAL::Random_points_in_triangle_mesh_3< TriangleMesh, VertexPointMap, Creator > Struct Template Reference

#include <CGAL/point_generators_3.h>

Definition

template<class TriangleMesh, class VertexPointMap = typename boost::property_map<TriangleMesh, CGAL::vertex_point_t>::type, class Creator = Creator_uniform_3< typename Kernel_traits< typename boost::property_traits<VertexPointMap>::value_type >::Kernel::RT, typename boost::property_traits<VertexPointMap>::value_type >>
struct CGAL::Random_points_in_triangle_mesh_3< TriangleMesh, VertexPointMap, Creator >

The class Random_points_in_triangle_mesh_3 is an input iterator creating points uniformly distributed inside the faces of a triangle mesh model of FaceListGraph.

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

Is model of
InputIterator
PointGenerator

◆ Random_points_in_triangle_mesh_3()

template<class TriangleMesh , class VertexPointMap = typename boost::property_map<TriangleMesh, CGAL::vertex_point_t>::type, class Creator = Creator_uniform_3< typename Kernel_traits< typename boost::property_traits<VertexPointMap>::value_type >::Kernel::RT, typename boost::property_traits<VertexPointMap>::value_type >>
CGAL::Random_points_in_triangle_mesh_3< TriangleMesh, VertexPointMap, Creator >::Random_points_in_triangle_mesh_3 ( const TriangleMesh &  mesh,
VertexPointMap  vpm,
Random rnd = get_default_random() 
)

Creates an input iterator g generating points of type Point_3 uniformly distributed in the mesh faces based on vpm.

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