Multiresolution Radiosity Caching for Efficient Preview and Final Quality Global Illumination in Movies|
Per H. Christensen, George Harker, Jonathan Shade, Brenden Schubert, Dana Batali
We present a multiresolution radiosity caching method that allows global illumination to be computed efficiently in a single pass in complex CG movie production scenes.
For distribution ray tracing in production scenes, the bottleneck is
the time spent evaluating complex shaders at the ray hit points. We
speed up this shader ... more
