Fast and Simple Occlusion Culling

Abstract: This article describes two occlusion culling algorithms that are practical, effective, and require little preprocessing. The first one is the prioritized-layered projection (PLP) algorithm, which is an approximate algorithm that determines, for a given budget, a set of primitives that is likely to be visible. The second algorithm, cPLP, is a conservative version of PLP that guarantees finding all visible primitives.

Sphere Trees for Fast Visibility Culling, Ray Tracing, and Range Searching

Abstract: The article presents an algorithm and demonstration application that manages thousands of objects in motion that are continuously maintained as a collection of hierarchical bounding spheres in a SphereTree. The design goal for this algorithm has been to make the 99-percentile case spend almost no CPU time updating an object in motion within the tree structure. Queries against the SphereTree perform more tests than other data structures, but this is mitigated by the fact that the tree can be maintained using very little CPU time. This data structure is ideally suited for gross culling of massive numbers of moving objects in a large world space. It doesn't matter if the objects are moving at widely disparate speeds, or even if many of them are not in motion at all. It also has a very low cost when objects are inserted and removed from the tree with great frequency.
