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. ...
Visibility-driven Mesh Analysis and Visualization through Graph Cuts
(IEEE Computer Society, 2008-11)
In this paper we present an algorithm that operates on a triangular mesh and classifies each face of a triangle as either inside or outside. We present three example applications of this core algorithm: normal orientation, ...
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 ...
