#include <CGAL/point_generators_3.h>

Definition

The class Random_points_on_sphere_3 is an input iterator creating points uniformly distributed on a sphere.

The default Creator is Creator_uniform_3<Kernel_traits<Point_3>Kernel::RT,Point_3>. 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.

Is Model Of:

InputIterator

PointGenerator

Constructor & Destructor Documentation

◆ Random_points_on_sphere_3()

template<typename Point_3 , typename Creator >
CGAL::Random_points_on_sphere_3< Point_3, Creator >::Random_points_on_sphere_3 ( double  r,
Random &  rnd = get_default_random() 
)

creates an input iterator g generating points of type Point_3 uniformly distributed on the boundary of a sphere with radius \( r\), i.e. \( |*g| == r\) .

Two random numbers are needed from rnd for each point.
