Abstract: A technique for real-time visualization of glossy surfaces is presented. The technique is aimed at recreating the view-dependent appearance of glossy surfaces under some fixed illumination conditions. The visualized surfaces can be actual real world surfaces or they can be surfaces for which the appearance is precomputed with a global illumination renderer. The approach taken is to image to surface from a large number of viewpoints distributed over the viewsphere. From these images the reflected radiance in different directions is sampled and a parameterized model is fitted to these radiance samples. Two different models are explored: a very low parameter model inspired by the Phong reflection model, and a general Spherical Harmonics model. It is concluded that the Phong-based model is best suited for this type of application.
