CGAL::Random_points_on_sphere_d< Point_d > Class Template Reference

#include <CGAL/point_generators_d.h>

## Definition

The class Random_points_on_sphere_d is an input iterator creating points uniformly distributed on a sphere.

The generated points are computed using floating point arithmetic, whatever the Kernel is, thus they are on the sphere only up to rounding errors.

Is Model Of:

InputIterator

## Operations

Random_points_on_sphere_d (int dim, double r, Random &rnd=get_default_random())
$$g$$ is an input iterator creating points of type Point_d uniformly distributed on a sphere in dimension $$dim$$ with radius $$r$$, i.e. $$|*g| == r$$ . More...

## ◆ Random_points_on_sphere_d()

template<typename Point_d>
 CGAL::Random_points_on_sphere_d< Point_d >::Random_points_on_sphere_d ( int dim, double r, Random & rnd = get_default_random() )

$$g$$ is an input iterator creating points of type Point_d uniformly distributed on a sphere in dimension $$dim$$ with radius $$r$$, i.e. $$|*g| == r$$ .

$$2\cdot dim$$ random numbers are needed from rnd for each point.
