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.
