Definition

template<typename Point_3, typename Triangle_3 = typename Kernel_traits<Point_3>::Kernel::Triangle_3, typename Creator = Creator_uniform_3< typename Kernel_traits< Point_3 >::Kernel::RT, Point_3 >>
struct CGAL::Random_points_in_triangles_3< Point_3, Triangle_3, Creator >

The class Random_points_in_triangles_3 is an input iterator creating points uniformly distributed inside a range of Triangle_3.

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

Is Model Of:

InputIterator

PointGenerator

Constructor & Destructor Documentation

◆ Random_points_in_triangles_3()

template<typename Point_3, typename Triangle_3 = typename Kernel_traits<Point_3>::Kernel::Triangle_3, typename Creator = Creator_uniform_3< typename Kernel_traits< Point_3 >::Kernel::RT, Point_3 >>
template<typename TriangleRange >
CGAL::Random_points_in_triangles_3< Point_3, Triangle_3, Creator >::Random_points_in_triangles_3 ( TriangleRange  triangulation,
Random rnd = get_default_random() 
)

Creates an input iterator g generating points of type Point_3 uniformly distributed between the triangles of the range.

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