Well, kind of.  The problem is that when the data is stored in the octree,
some 'level-of-detail' information is stored with it, which affects the way
the octree is searched.  So, if stuff is stored on a distant wall, it is
stored with a low level of detail, but if you walk up close to it, you'd
like to store more data there, if possible.

Plus, it is very important to store and read data in the octree using the
same level of detail for both store and read.  (This was a bug in the
original implementation, which led to splotchiness... sometimes it would
store with one level-of-detail, and then gather using another
level-of-detail).
