## Definition

template<typename Point_3, typename Creator>
class CGAL::Random_points_in_triangle_3< Point_3, Creator >

The class `Random_points_in_triangle_3` is an input iterator creating points uniformly distributed inside a 3D triangle.

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

Is model of
  `InputIterator`
  `PointGenerator`

| Random_points_in_triangle_3 (Triangle_3 &t, Random &rnd=get_default_random())
| Creates an input iterator `g` generating points of type `Point_3` uniformly distributed inside a 3D triangle \(t\) with vertices \( p, q \) and \( r \), i.e., \(*g = \alpha p + \beta q + \gamma r \), for some \( \alpha, \beta, \gamma \in [0, 1] \) and \( \alpha + \beta + \gamma = 1 \).

## Constructor & Destructor Documentation

## ◆ Random_points_in_triangle_3() [1/2]

template<typename Point_3 , typename Creator >

CGAL::Random_points_in_triangle_3< Point_3, Creator >::Random_points_in_triangle_3 | ( | Point_3 & | p,
|  | Point_3 & | q,
|  | Point_3 & | r,
|  | Random & | rnd = `get_default_random()`
| ) |  |

Creates an input iterator `g` generating points of type `Point_3` uniformly distributed inside the 3D triangle with vertices \( p, q \) and \( r \), i.e., \(*g = \alpha p + \beta q + \gamma r \), for some \( \alpha, \beta, \gamma \in [0, 1] \) and \( \alpha + \beta + \gamma = 1 \).

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

## ◆ Random_points_in_triangle_3() [2/2]

template<typename Point_3 , typename Creator >

CGAL::Random_points_in_triangle_3< Point_3, Creator >::Random_points_in_triangle_3 | ( | Triangle_3 & | t,
|  | Random & | rnd = `get_default_random()`
| ) |  |

Creates an input iterator `g` generating points of type `Point_3` uniformly distributed inside a 3D triangle \(t\) with vertices \( p, q \) and \( r \), i.e., \(*g = \alpha p + \beta q + \gamma r \), for some \( \alpha, \beta, \gamma \in [0, 1] \) and \( \alpha + \beta + \gamma = 1 \).

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