So I finally got my mesh loader rolling I now only have the SG and spatial partitioning left. What I had originally planned was having was having a normal scenegraph where each mesh node has an AABBTree, which then would be stored in an octree. Now while implementing i started wondering if this design would actually suffice? Now i know there ain't one answer for this question but do people have better suggestions? I've heard alot about ABT trees(?) but couldn't find anything real on them. Anybody have ressources about these in hand? [Edited by - JSoftware on March 30, 2006 12:40:24 PM]
