#include <CGAL/Orthogonal_incremental_neighbor_search.h>
The class Orthogonal_incremental_neighbor_search
implements incremental nearest and furthest neighbor searching on a tree.
Traits | must be a model of the concept SearchTraits , for example Search_traits_2<Simple_cartesian<double> > . |
OrthogonalDistance | must be a model of the concept OrthogonalDistance . If Traits is Search_traits_adapter<Key,PointPropertyMap,BaseTraits> the default type is Distance_adapter<Key,PointPropertyMap,Euclidean_distance<BaseTraits> > , and Euclidean_distance<Traits> otherwise. |
Splitter | must be a model of the concept Splitter . The default type is Sliding_midpoint<Traits> . |
SpatialTree | must be a model of the concept SpatialTree . The default type is Kd_tree<Traits, Splitter, Tag_true> . The template argument must be Tag_true because orthogonal search needs extended kd tree nodes. |
