#include <CGAL/point_generators_3.h>
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.

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.
