# Class: dspacequad

The quadtree is suited for collision that is mostly planar. However the use of this class is not recommend.

## Methods:

new ([dspace space],[float cx,cy,cz, float w,h,d, int depth])
  returns: (dspacequad)
  Creates a quadtree space. center and extents define the size of the root block. depth sets the depth of the tree - the number of blocks that are created is 4^depth

## Inherited Methods:
