CGAL::perturb_points_2

Definition

The function perturb_points_2 perturbs each point in a given range of points by a random amount.

#include <CGAL/point_generators_2.h>

template <class ForwardIterator>
void	perturb_points_2 ( ForwardIterator first, ForwardIterator last, double xeps, double yeps = xeps, Random& rnd = default_random, Creator creator = Creator_uniform_2<Kernel_traits<P>::Kernel::RT,P>)
		perturbs the points in the range $$[first,last) by replacing each point with a random point from the xeps $$ × yeps rectangle centered at the original point. Two random numbers are needed from rnd for each point.

Requirements

• Creator must be a function object accepting two double values $$x and $$y and returning an initialized point (x,y) of type P.

  Predefined implementations for these creators like the default are described in Section 45.5.

• The value_type of the ForwardIterator must be assignable to P.
• P is equal to the value_type of the ForwardIterator when using the default initializer.
• The expressions to_double((*first).x()) and to_double((*first).y()) must result in the respective coordinate values.
