| Abstract: | In many applications it is important to perform image-based relighting. That is, to synthesize a scene in various lighting conditions without explicitely rerendering the image. This paper proposes an efficient compression method, which after a precomputing step allows an efficient re-rendering of the scene. The best results are achieved on scenes with a limited number of materials, but it may also be used on arbitrary scenes. In this work images of a static scene are generated and the method is exemplified using a dataset of ray-traced images.
