- 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...

simpler representation. If
nodes are
being shared between quadtrees representing different timesteps, then only
those nodes which were newly...
- 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 can be used for

partitioning index with a

unlike quadtrees, it uses a
