Precomputing Sound Scattering for Structured Surfaces
(The Eurographics Association, 2014)
Room acoustic simulations commonly use simple models for sound scattering on surfaces in the scene. However, the continuing increase of available parallel computing power makes it possible to apply more sophisticated models. ...
Reduced Precision for Hardware Ray Tracing in GPUs
(The Eurographics Association, 2014)
We propose a high performance, GPU integrated, hardware ray tracing system. We present and make use of a new analysis of ray traversal in axis aligned bounding volume hierarchies. This analysis enables compact traversal ...
Exploiting Local Orientation Similarity for Efficient Ray Traversal of Hair and Fur
(The Eurographics Association, 2014)
Hair and fur typically consist of a large number of thin, curved, and densely packed strands which are difficult to ray trace efficiently. A tight fitting spatial data structure, such as a bounding volume hierarchy (BVH), ...
