CGAL::Random_points_on_circle_2< Point_2, Creator > Class Template Reference

#include <CGAL/point_generators_2.h>

## Definition

The class Random_points_on_circle_2 is an input iterator creating points uniformly distributed on a circle.

The default Creator is Creator_uniform_2<Kernel_traits<Point_2>Kernel::RT,Point_2>. The generated points are computed using floating point arithmetic, whatever the Kernel is, thus they are on the circle/sphere only up to rounding errors.

Random_points_on_circle_2 (double r, Random &rnd=get_default_random())
creates an input iterator g generating points of type Point_2 uniformly distributed on the circle with radius $$r$$, i.e. $$|*g| == r$$. More...

## ◆ Random_points_on_circle_2()

template<typename Point_2, typename Creator>
 CGAL::Random_points_on_circle_2< Point_2, Creator >::Random_points_on_circle_2 ( double r, Random & rnd = get_default_random() )

creates an input iterator g generating points of type Point_2 uniformly distributed on the circle with radius $$r$$, i.e. $$|*g| == r$$.

A single random number is needed from rnd for each point.
