## Constructor & Destructor Documentation

template<typename Point_3 , typename Creator >

CGAL::Random_points_in_sphere_3< Point_3, Creator >::Random_points_in_sphere_3 | ( | double | r,
|  | Random & | rnd = `default_random`
| ) |  |

creates an input iterator `g` generating points of type `Point_3` uniformly distributed in the open sphere with radius \( r\), i.e. \( |*g| < r\) .

Three random numbers are needed from `rnd` for each point.
