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.
