CGAL::Random_points_on_sphere_d< Point_d > Class Template Reference

#include <CGAL/point_generators_d.h>

Definition

template<typename Point_d>
class CGAL::Random_points_on_sphere_d< Point_d >

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

	)

\( g\) 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.
