GPU-Based Light Wavefront Simulation for Real-Time Refractive Object Rendering

This sketch presents technical implementation details for the SIGGRAPH 2007 paper Eikonal Rendering: Efficient Light Transport in Refractive Objects. It describes the GPU-based wavefront simulation through refractive objects and the rendering pass.

Radiance Caching for Participating Media

An extension of irradiance caching to participating media. This method is several orders of magnitude faster then path tracing and can efficiently handle scenes that are difficult for photon mapping.
