"WebMar 23, 2007 · In this article I had studied the performance of the k-d tree for nearest-neighbour search. The analyses shows that k-d works quite well for small dimensions. However the number of the searched nodes rises exponentially with the space dimension and for N>10 k-d may become too slow. Another drawback is that the bassic k-d tree do … " - C# accord kdtree

KD-trees provide fast range searching and fast lookup for point data. The tree is built dynamically by inserting points. The tree supports queries by range and for point equality. For querying an internal stack is used instead of recursion to avoid overflow.
