Description: Ren Ng, Ravi Ramamoorthi and Pat Hanrahan presents a method, based on pre-computed light transport, for real-time rendering of objects under all-frequency, time-varying illumination represented as a high-resolution environment map. This gives good shadows.
All-Frequency Shadows Using Non-linear Wavelet Lighting Approximation ACM Transactions on Graphics, July 2003 We present a method, based on pre-computed light transport, for real-time rendering of objects under all-frequency, time-varying illumination represented as a high-resolution environment map. Current techniques are limited to small area lights, with sharp shadows, or large low-frequency lights, with very soft shadows. Our main contribution is to approximate the environment map in a wavelet basis, keeping only the largest terms (this is known as a
