Abstract:
Understanding intricate details of carved models, for example ones prevalent in cultural heritage applications, is often difficult from renderings using traditional illumination models. A number of illustrative rendering techniques are known, but each works well only for some models. We present a rendering system that combines these techniques in an attempt to make the visualization more comprehensible given any context. In particular, our system learns user's visual preferences using exemplars from a domain and applies an appropriate combination of the basis techniques to new meshes from that domain. Given a polygonal mesh, the system applies different rendering techniques to different parts based on local features in order to enhance the overall appearance.
