Constructor & Destructor Documentation

template<typename Point_2 , typename Creator >
CGAL::Random_points_on_square_2< Point_2, Creator >::Random_points_on_square_2 ( double  a,
Random rnd = default_random 
)

creates an input iterator g generating points of type Point_2 uniformly distributed on the boundary of the square with side length \( 2 a\), centered at the origin, i.e. \( \forall p = *g:\) one coordinate is either \( a\) or \( -a\) and for the other coordinate \( c\) holds \( -a \le c < a\).

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