A quadtree is a tree data structure in which each internal node has exactly four children. All forms of quadtrees share some common features:• They decompose space into adaptable cells.• Each cell (or bucket) has a maximum capacity. When maximum capacity is reached, the bucket splits.• The tree directory follows the spatial decomposition of the quadtree.
