The paper "Precomputed Local Radiance Transfer for Real-Time Lighting Design" extends precomputed radiance transfer (PRT) for distance lighting to local lighting.This is done by following steps. 0. Dense uniform sampling of light sources i…

Vector Quantization (VQ) is used to compress the input vectors to a small number of vectors by using some kind of algorithms.These are some basic algorithms for doing it. K-Means [0] Linde-Buzo-Gray (LBG) Algorithm[1][2] Pairwise Nearest N…
