%description

|
Algorithm::QuadTree implements a quadtree algorithm (QTA) in pure Perl.
|
|
Essentially, a QTA is used to access a particular area of a map very quickly.
|
|
This is especially useful in finding objects enclosed in a given region, or in
|
|
detecting intersection among objects. In fact, I wrote this module to rapidly
|
|
search through objects in a Tk::Canvas widget, but have since used it in other
|
|
non-Tk programs successfully. It is a classic memory/speed trade-off.
|
|
|
|
Lots of information about QTAs can be found on the web. But, very briefly, a
|
|
quadtree is a hierarchical data model that recursively decomposes a map into
|
|
smaller regions. Each node in the tree has 4 children nodes, each of which
|
|
represents one quarter of the area that the parent represents. So, the root node
|
|
represents the complete map. This map is then split into 4 equal quarters, each
|
|
of which is represented by one child node. Each of these children is now treated
|
|
as a parent, and its area is recursively split up into 4 equal areas, and so on
|
|
up to a desired depth.
