Abstract

In Augmented Reality applications it is important to have a good description of the surfaces of real objects if a consistent shading between real and virtual object is required. If such a description of a surface is not vailable it has to be estimated or approximated. In our paper we will present certain methods that deal with real-time bi-directional reflectance distribution function (BRDF) approximation in augmented reality. Of course an important thing to discuss is whether the applications we present all work in real-time and compute good (and real)looking results. There are different methods on how to achieve this goal. All of the methods we are going to present work via image based lighting and some require a 3D polygonal mesh representation of the object whose BRDF shall be approximated. Some methods estimate the BRDF parameters via error values and provide results at each iteration.
