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

#include <CGAL/point_generators_2.h>

Definition

template<typename Point_2, typename Creator>
class CGAL::Random_points_on_circle_2< Point_2, Creator >

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.

Constructor & Destructor Documentation

◆ 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.
