CGAL::Random_points_in_triangles_2< Point_2, Triangle_2, Creator > Struct Template Reference

#include <CGAL/point_generators_2.h>

Definition

template<typename Point_2, typename Triangle_2 = typename Kernel_traits<Point_2>::Kernel::Triangle_2, typename Creator = Creator_uniform_2<typename Kernel_traits<Point_2>::Kernel::RT,Point_2>>
struct CGAL::Random_points_in_triangles_2< Point_2, Triangle_2, Creator >

The class Random_points_in_triangles_2 is an input iterator creating points uniformly distributed inside a range of Triangle_2.

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

Is model of
InputIterator

Constructor & Destructor Documentation

◆ Random_points_in_triangles_2()

template<typename Point_2 , typename Triangle_2 = typename Kernel_traits<Point_2>::Kernel::Triangle_2, typename Creator = Creator_uniform_2<typename Kernel_traits<Point_2>::Kernel::RT,Point_2>>
template<typename TriangleRange >
CGAL::Random_points_in_triangles_2< Point_2, Triangle_2, Creator >::Random_points_in_triangles_2 ( const TriangleRange &  triangles,
Random rnd = get_default_random() 
)

Creates an input iterator g generating points of type Point_2 uniformly distributed between the triangles of the range.

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