K-d trees in data structure
WebThe resulting data structure is called a point kd-tree. Actually, this is a bit of a misnomer. The data structure was named by its inventor Jon Bentley to be a 2-d tree in the plane, a 3-d tree in 3-space, and a k-d tree in dimension k. However, over time the name \kd-tree" became commonly used irrespective of dimension. Webflat tiling structure. quadtree. quad- or octree structure (depending on index dimension) kdtree. kd-tree structure. rtree. r-tree structure. Count. number of elements.
