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.

	)

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 \( \alpha + \beta + \gamma = 1 \).
