void hilbert_sort(InputPointIterator begin, InputPointIterator end, const Traits &traits=Default_traits, PolicyTag policy=Default_policy)
The function hilbert_sort() sorts an iterator range of points along a Hilbert curve.
Hilbert_policy is a policy class which can be used to parameterize a strategy policy in order to spec...
