   Result of an Octree Search...
   It''s usually common the need of processing the visible objects of a scene more than once per update (e.g. for collision, shadow calculations, etc...). How do you procede in these situations? You go through the Octree more than once on the fly? Or should be better to build a linked list of the visible objects at the fist run at that frame, and then use it for the former processings? Thanks!
