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`

  `PointGenerator`

## Operations

| Random_points_on_sphere_d (int dim, double r, Random &rnd=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...

## Constructor & Destructor Documentation

template<typename Point_d>

CGAL::Random_points_on_sphere_d< Point_d >::Random_points_on_sphere_d | ( | int | dim,
|  | double | r,
|  | Random & | rnd = `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.
