## Definition

template<typename Point_3, typename Creator>
class CGAL::Random_points_in_cube_3< Point_3, Creator >

The class `Random_points_in_cube_3` is an input iterator creating points uniformly distributed in a half-open cube.

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

Is model of
  `InputIterator`
  `PointGenerator`

| Random_points_in_cube_3 (double a, Random &rnd=get_default_random())
| Creates an input iterator `g` generating points of type `Point_3` uniformly distributed in the half-open cube with side length \( 2 a\), centered at the origin, i.e. \( \forall p = *g: -a \le p.x(),p.y(),p.z() < a\) .

## Constructor & Destructor Documentation

## ◆ Random_points_in_cube_3()

template<typename Point_3 , typename Creator >

CGAL::Random_points_in_cube_3< Point_3, Creator >::Random_points_in_cube_3 | ( | double | a,
|  | Random & | rnd = `get_default_random()`
| ) |  |

Creates an input iterator `g` generating points of type `Point_3` uniformly distributed in the half-open cube with side length \( 2 a\), centered at the origin, i.e. \( \forall p = *g: -a \le p.x(),p.y(),p.z() < a\) .

Three random numbers are needed from `rnd` for each point.
