description: A central motivation of computer graphics research is the generation of images, which approximate views of objects with sufficient detail as to render the distinction between the real and the artificial difficult or impossible. Much of the required visual complexity can be found on the surfaces of objects. Rich textures, such as animal fur or heavy cloths, introduce a level of detail which is immediately recognized as natural by the human visual system. It is, however, the detail of complex macro-structured surfaces which makes them difficult to model and expensive to render. Presented in this thesis is a new method for the rendering of complex natural surfaces, which combines traditional 2D texturing and light field rendering. Here, real surfaces are approximated utilizing light emitted from complex surfaces, captured and tiled as surface light textures. As a form of texturing this method inherits issues associated with other types of texturing. But, with this new form of texturing we also see the introduction of research problems that are unique to the method. For example, lowincidence object silhouettes are given special consideration as the real texture edges are grafted at surface silhouettes to avoid unrealistic smooth polygonal or spline boundaries. Moreover, we partially overcome the static nature of light fields with a complementary technique which animates the parameter space of the light field rather than the original captured object.
