Constructor & Destructor Documentation

template<typename Point_2, typename Creator>
CGAL::Random_points_on_segment_2< Point_2, Creator >::Random_points_on_segment_2 ( const Point_2 &  p,
const Point_2 &  q,
Random &  rnd = get_default_random() 
)

creates an input iterator g generating points of type Point_2 uniformly distributed on the segment from p to q (excluding q), i.e. ∗g==(1−λ)p+λq where 0≤λ<1.

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