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 = get_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.
