     6    - for collision detection: only a subset of all triangles need to be tested vs a given body
     7    - for object culling purposes: the quadtrees that are not in the field of view can be ommitted in the draw process
     8    - for LOD (level of Detail). The models can be drawn using different LODs depending on the distance
