Fast Rendering of Reflections in Non-uniform Surfaces Using a Multi-Scale Environment Map
Conventionally, it is difficult to render non-uniform roughness surfaces in real time. This sketch presents a real-time rendering technique for such materials using a multi-scale environment map.

A Smooth, Fast, Accurate Representation of Reflectance
A representation of reflectance, especially measured reflectance data, that is both smooth and time-efficient. By fitting a multi-level B-spline approximation to BRDF data, the method can obtain a continuous function that matches the data to arbitrary precision.

Interactive Rendering of Translucent Deformable Objects
An algorithm for plausible reproduction of subsurface scattering effects. Unlike previously proposed work, this algorithm allows interactive lighting change, viewpoint, subsurface scattering properties, and even geometry.
