Constructor & Destructor Documentation

template<typename Point_2 , typename Creator >
CGAL::Random_points_in_triangle_2< Point_2, Creator >::Random_points_in_triangle_2 ( Point_2 &  p,
Point_2 &  q,
Point_2 &  r,
Random &  rnd = get_default_random() 
)

Creates an input iterator g generating points of type Point_2 uniformly distributed inside the triangle with vertices p,q and r, i.e., ∗g=αp+βq+γr, for some α,β,γ∈[0,1] and α+β+γ=1.

Two random numbers are needed from rnd for each point.
