Temporally Coherent Conservative Visibility

Abstract

Efficiently identifying polygons that are visible from a changing synthetic viewpoint is an important problem in computer graphics. even with hardware support, simple algorithms like depth-buffering cannot achieve interactive frame rates when applied to geometric models with many polygons. However, a visibility algorithm that exploits the occlusion properties of the scene to identify a superset of visible polygons, without touching most invisible polygons, could achieve fast rates while viewing such models.
