Improved Bounds for Orthogonal Point Enclosure Query and Point

... Table 1: Summary of our results for orthogonal point enclosure in R3 . log∗ n is the iterated logarithm of n. log(1) n = log n and log(i) n = log(log(i−1) n) when i > 1 is a constant integer. Existing solutions in the literature for 6-sided rectangles require Ω(n log n) space. comparison of our resu ...

Quadtree



A quadtree is a tree data structure in which each internal node has exactly four children. Quadtrees are most often used to partition a two-dimensional space by recursively subdividing it into four quadrants or regions. The regions may be square or rectangular, or may have arbitrary shapes. This data structure was named a quadtree by Raphael Finkel and J.L. Bentley in 1974. A similar partitioning is also known as a Q-tree. 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.
