CGAL::Random_points_on_sphere_3< Point_3, Creator > Class Template Reference

#include <CGAL/point_generators_3.h>

## Definition

The class Random_points_on_sphere_3 is an input iterator creating points uniformly distributed on a sphere.

The default Creator is Creator_uniform_3<Kernel_traits<Point_3>Kernel::RT,Point_3>. The generated points are computed using floating point arithmetic, whatever the Kernel is, thus they are on the circle/sphere only up to rounding errors.

## ◆ Random_points_on_sphere_3()

template<typename Point_3 , typename Creator >
 CGAL::Random_points_on_sphere_3< Point_3, Creator >::Random_points_on_sphere_3 ( double r, Random & rnd = get_default_random() )

creates an input iterator g generating points of type Point_3 uniformly distributed on the boundary of a sphere with radius $$r$$, i.e. $$|*g| == r$$ .

Two random numbers are needed from rnd for each point.
