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 = 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. \( *g == (1-\lambda)\, p + \lambda q\) where \( 0 \le\lambda< 1\).

A single random number is needed from rnd for each point.

Requires:
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 \( q\).
