void	perturb_points_2 (ForwardIterator first, ForwardIterator last, double xeps, double yeps=xeps, Random &rnd=get_default_random(), Creator creator=Creator_uniform_2< Kernel_traits< P >::Kernel::RT, P >)
	perturbs each point in a given range of points by a random amount.
template<class P , class OutputIterator >
OutputIterator	points_on_segment_2 (const P &p, const P &q, std::size_t n, OutputIterator o)
	generates a set of points equally spaced on a segment given the endpoints of the segment.
template<class OutputIterator , class Creator >
OutputIterator	points_on_square_grid_2 (double a, std::size_t n, OutputIterator o, Creator creator=Creator_uniform_2< Kernel_traits< P >::Kernel::RT, P >)

	randomly chooses two points from the range [first,last), creates a random third point on the segment connecting these two points, writes it to first2, and repeats this $n$ times, thus writing $n$ points to first2 that are collinear with points in the range [first,last).
