All-Frequency Precomputed Radiance Transfer for Glossy Objects
Xinguo Liu, Peter‐Pike Sloan, Heung‐Yeung Shum, John Snyder · Eurographics Symposium on Rendering Techniques · 2004
We introduce a method based on precomputed radiance transfer (PRT) that allows interactive rendering of glossy surfaces and includes shadowing effects from dynamic, "all-frequency" lighting. Specifically, source lighting is represented by a cube map at resolution nL
