Constructor & Destructor Documentation

template<typename Point_2, typename Creator>

CGAL::Random_points_in_disc_2< Point_2, Creator >::Random_points_in_disc_2	(	double	r,
		Random &	rnd = get_default_random()
	)

Creates an input iterator g generating points of type Point_2 uniformly distributed in the open disc with radius \( r\), i.e. \( |*g| < r\).

Two random numbers are needed from rnd for each point.
