Another question about Octrees
Author
I have another question about Octrees. I think I understood the basic system of the tree structure. But I dont really know what is exactly saved in the nodes / subnodes?
Please help me, because that is the problem I''m "fighting" with.
Ronin,
In Octree, the Virtual Space is defined as the root Noot (1st node). The cube is divided in 8 Quadrant, thosw new quadrant are divided in 8 new ones. You store you polygons in it (ptr to them is more efficent).
Happy Coding,
Lowrad.

Just a little word to say that you save your polygons in the smallest nodes, not in each node that contains it.
(Or you will have a HUGE waste of memory)
Include PVS and NVS in the structure, it''s usefull.
