Octree
</h2>
<div class="class-description"><p>A Octree implementation. The original code was a conversion of the Java code posted to GameDevTuts.
However I've tweaked it massively to add node indexing, removed lots of temp. var creation and significantly increased performance as a result.
Original version at <a href="https://github.com/timohausmann/quadtree-js/">https://github.com/timohausmann/quadtree-js/</a></p></div>
