| Creates an input iterator `g` generating points of type `Point_3` uniformly distributed inside a tetrahedron \(t\) with vertices \( p, q, r \) and \( s \), i.e., \(*g = \alpha p + \beta q + \gamma r + \delta s \), for some \( \alpha, \beta, \gamma, \delta \in [0, 1] \) and \( \alpha + \beta + \gamma + \delta = 1 \).

## Constructor & Destructor Documentation

## ◆ Random_points_in_tetrahedron_3() [1/2]

template<typename Point_3 , typename Creator >

CGAL::Random_points_in_tetrahedron_3< Point_3, Creator >::Random_points_in_tetrahedron_3 | ( | Point_3 & | p,
|  | Point_3 & | q,
|  | Point_3 & | r,
|  | Point_3 & | s,
|  | Random & | rnd = `get_default_random()`
| ) |  |

Creates an input iterator `g` generating points of type `Point_3` uniformly distributed inside the tetrahedron with vertices \( p, q, r \) and \( s \), i.e., \(*g = \alpha p + \beta q + \gamma r + \delta s \), for some \( \alpha, \beta, \gamma, \delta \in [0, 1] \) and \( \alpha + \beta + \gamma + \delta = 1 \).

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