Hi,
a very brief look made me think that your boolean model is fairly similar to
a data structure called quadtree (2D) or octree (3D), which is used in
computer graphics and spatial reasoning. You may want to look up Google or
data structure textbooks on this. I may well have missed things; my look was
very cursory. (Very nice pictures, btw!) Good luck,
Philip
