Bsp octree
WebA BSP is better for a smaller, simpler space that you only want to do occlusion with. If you want all intersections for a given ray, you'll need to upgrade to a quad/octree. As for … WebBSP trees are useful for building an "exact cell decomposition". A cell is any region which is used as a node in a planning graph. An exact cell decomposition is one in which every …
