Reflection space image based rendering

摘要

High quality,physically accurate rendering at interactive rates has widespread application,but is a daunting task.We attempt to bridge the gap between high-quality offline and interactive rendering by using existing environemtn mapping hardware in combination with a novel Image Based Rendering (IBR) alogrithm.The primary ocntributin lies in perorming IBR in reflection space.This mehtod cna be applied to ordinary environment maps,but for more physically accurte rendering,we apply reflection space IBR to radiance environemtn maps.
