Definition of Quadtrees. Meaning of Quadtrees. Synonyms of Quadtrees

- Like the point quadtree, the PR quadtree may also have a linear height when given a "bad" set. Edge quadtrees (much like PM quadtrees) are used to store...
- tree. This allows points to be added and deleted in O(log n) time. Two quadtrees can be merged by merging the two sorted sets of points, and removing duplicates...
- subdividing it into eight octants. Octrees are the three-dimensional analog of quadtrees. The word is derived from oct (Gr**** root meaning "eight") + tree. Octrees...
- constant k > 1. The algorithm uses shifted quadtrees. The key concept of the algorithm is alignment to the quadtree grid. An object of size r is called k-aligned...
- the use of new RT (ray-tracing) cores, which are designed to process quadtrees and spherical hierarchies, and speed up collision tests with individual...
- generalization of other spatial tree structures such as k-d trees and quadtrees, one where hyperplanes that partition the space may have any orientation...
- Quadtrees can be used for hierarchical path finding...
- accelerated by the use of new RT cores, which are designed to process quadtrees and spherical hierarchies, and speed up collision tests with individual...
