Production Volume Rendering|
Julian Fong, Magnus Wrenninge, Christopher Kulla, Ralf Habel
This course provides an overview of production volume rendering, focused on path tracing. The course will describe practical fundamentals for adding volume rendering to an existing path tracer, cover a complete range of volume integration scenarios and techniques, and describe in detail recent production-proven techniques for optimizing volume rendering.

Ray Tracing for the Movie 'Cars'|
Per H. Christensen, Julian Fong, David M. Laur, Dana Batali
This paper describes how we extended Pixar's RenderMan renderer with ray tracing abilities. In order to ray trace highly complex scenes we use multiresolution geometry and texture caches, and use ray differentials to determine the appropriate resolution. With this method we are able to efficiently ray trace scenes with much more geometry and ... more

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
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
