CGAL::perturb_points_2

Definition

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

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 69.8.
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.
