CGAL::Random_points_on_square_2<Point_2, Creator>

Definition

The class Random_points_on_square_2<Point_2, Creator> is an input iterator creating points uniformly distributed in the boundary of a square. The default Creator is Creator_uniform_2<Kernel_traits<P>::Kernel::RT,P>.

Operations

Random_points_on_square_2<Point_2, Creator> g ( double a, Random& rnd = default_random);
g is an input iterator creating points of type Point_2 uniformly distributed on the boundary of the square with side length 2 a, centered at the origin, i.e.  for all p = *g: one coordinate is either a or -a and for the other coordinate c holds -a c < a . A single random number is needed from rnd for each point.
