	Random_points_on_segment_3 (const Point_3 &p, const Point_3 &q, Random &rnd=get_default_random())
	creates an input iterator g generating points of type Point_3 uniformly distributed on the segment from \( p\) to \( q\) (excluding \( q\)), i.e. \( *g == (1-\lambda)\, p + \lambda q\) where \( 0 \le\lambda< 1\).

Constructor & Destructor Documentation

Random_points_on_segment_3()

template<typename Point_3 , typename Creator >

CGAL::Random_points_on_segment_3< Point_3, Creator >::Random_points_on_segment_3	(	const Point_3 &	p,
		const Point_3 &	q,
		Random &	rnd = get_default_random()
	)

creates an input iterator g generating points of type Point_3 uniformly distributed on the segment from \( p\) to \( q\) (excluding \( q\)), i.e. \( *g == (1-\lambda)\, p + \lambda q\) where \( 0 \le\lambda< 1\).

A single random number is needed from rnd for each point. The expressions to_double(p.x()), to_double(p.y()), and to_double(p.z()) must result in the respective double representation of the coordinates of \( p\), and similarly for \( q\).
