WebMay 5, 2011 · Abstract. We present an efficient algorithm for building an adaptive bounding volume hierarchy (BVH) in linear time on commodity graphics hardware using CUDA. BVHs are widely used as an acceleration data structure to quickly ray trace animated polygonal scenes. We accelerate the construction process with auxiliary grids that help us build … WebExperiments show that for deforming triangle meshes the reconstruction time of the bounding volume hierarchies per frame can be reduced by an order of magnitude compared to previous approaches, which also results in a signican t speed-up in the total rendering time for many types of dynamically changing scenes.
