Arithmetic operations between quadtrees #4
Description
It'd be cool if quadtrees could be subtracted, added, etc.
This would likely involve some of quadtree "union" or something - basically, if I wanted to preserve all the possible info, I'd need to have the resulting quadtree take on the smallest resolution of any cell. Basically, if one quadtree has a single cell in one area, and the other has that same area broken into multiple levels, the resulting quadtree would need to take on the structure of the more detailed quadtree in order to preserve the data in the smaller cells.
