Abstract

We present a novel method for checking the intersection of polygonal models on graphics hardware utilizing its SIMD, occlusion query, and floating point texture capabilities. It consists of two stages: traversal of bounding volume hierarchies, thus quickly determining potentially intersecting sets of polygons, and the actual intersection tests, resulting in lists of intersecting polygons. Unlike previous methods, our method does all computations in object space and does not make any requirements on connectivity or topology.

Keywords

GPU-based general purpose computing, p-buffers, superbuffers.
