Fast Insertion-Based Optimization of Bounding Volume Hierarchies
(Eurographics Association, Wiley-Blackwell, 2013-02)
We present an algorithm for fast optimization of bounding volume hierarchies (BVH) for efficient ray tracing. We perform selective updates of the hierarchy driven by the cost model derived from the surface area heuristic. ...
Adaptive Global Visibility Sampling
(Association for Computing Machinery (ACM), 2009)
In this paper we propose a global visibility algorithm which computes from-region visibility for all view cells simultaneously in a progressive manner. We cast rays to sample visibility interactions and use the information ...
