## Classes
struct | Hilbert_policy
| `Hilbert_policy` is a policy class which can be used to parameterize a strategy policy in order to specify the strategy for spatial sorting. More...
class | Hilbert_sort_2
| The function object `Hilbert_sort_2` sorts iterator ranges of `Traits::Point_2` along a Hilbert curve by recursively subdividing at the median or the middle, depending on the `PolicyTag` (see Section Hilbert Sorting for more information on the policies). More...
class | Hilbert_sort_3
| The function object `Hilbert_sort_3` sorts iterator ranges of `Traits::Point_3` along a Hilbert curve by recursively subdividing at the median or the middle, depending on the `PolicyTag`(see Section Hilbert Sorting for more information on the policies). More...
class | Hilbert_sort_d
| The function object `Hilbert_sort_d` sorts iterator ranges of `Traits::Point_d` along a Hilbert curve by recursively subdividing at the median or the middle depending on the `PolicyTag`. More...
class | Hilbert_sort_on_sphere_3
| The function object `Hilbert_sort_on_sphere_3` sorts iterator ranges of `Traits::Point_3` along a Hilbert curve on a given sphere. More...
struct | Median
| `Median` is a tag class. More...
struct | Middle
| `Middle` is a tag class. More...
class | Multiscale_sort
| The class `Multiscale_sort` represents a sorting algorithm adaptor. More...
class | Spatial_sort_traits_adapter_2
| Given a property map associating a key to a point, the class `Spatial_sort_traits_adapter_2` induces a spatial reorder of the keys instead of the points, the comparisons being done on the associated points. More...
class | Spatial_sort_traits_adapter_3
| Given a property map associating a key to a point, the class `Spatial_sort_traits_adapter_3` induces a spatial reorder of the keys instead of the points, the comparisons being done on the associated points. More...
class | Spatial_sort_traits_adapter_d
| Given a property map associating a key to a point, the class `Spatial_sort_traits_adapter_d` induces a spatial reorder of the keys instead of the points, the comparisons being done on the associated points. More...

## Typedefs
typedef Hilbert_policy< Median > | Hilbert_sort_median_policy
| A typedef to `Hilbert_policy<Median>`.
typedef Hilbert_policy< Middle > | Hilbert_sort_middle_policy
| A typedef to `Hilbert_policy<Middle>`.

## Functions
template<class ConcurrencyTag = Sequential_tag, class InputPointIterator , class Traits , class PolicyTag >
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.
template<class InputPointIterator , class Traits , class PolicyTag >
void | hilbert_sort_on_sphere (InputPointIterator begin, InputPointIterator end, const Traits &traits=Default_traits, PolicyTag policy=Default_policy, double sqr_radius=1.0, const Traits::Point_3 &center=Default_center)
| The function `hilbert_sort_on_sphere()` sorts an iterator range of points that are supposed to be close to a given sphere along a Hilbert curve on that same sphere.
template<class ConcurrencyTag = Sequential_tag, class InputPointIterator , class Traits , class PolicyTag >
void | spatial_sort (InputPointIterator begin, InputPointIterator end, const Traits &traits=Default_traits, PolicyTag policy=Default_policy, std::ptrdiff_t threshold_hilbert=default, std::ptrdiff_t threshold_multiscale=default, double ratio=default)
| The function `spatial_sort()` sorts an iterator range of points in a way that improves space locality.
