template<typename Point_3 , typename Creator >
CGAL::Random_points_in_cube_3< Point_3, Creator >::Random_points_in_cube_3 ( double  a,
Random &  rnd = default_random 
)

Creates an input iterator g generating points of type Point_3 uniformly distributed in the half-open cube with side length \( 2 a\), centered at the origin, i.e. \( \forall p = *g: -a \le p.x(),p.y(),p.z() < a\) .

Three random numbers are needed from rnd for each point.
