Ray Differentials and Multiresolution Geometry Caching for Distribution Ray
Tracing in Complex Scenes Per H. Christensen, David M. Laur, Julian Fong, Wayne L. Wooten, Dana Batali September 2003 When rendering only directly visible objects, ray tracing a few levels of specular reflection from large, low curvatures surfaces, and ray tracing shadows from point-like light sources, the accessed geometry is coherent and a geometry cache performs well. But in many other cases, ... more Paper (PDF) Published as pp. pp. 543-552 in Computer Graphics Forum (Eurographics 2003 Conference Proceedings), Blackwell Publishers, September 2003. |
