I'll check it out. And yes, I know about non-photorealistic rendering (via Bob), but don't know where I can find more about that, actually. Probably SIGGRAPH too? About LOD: architects have a bit of different view on LOD than CG people.. LOD is often reffered to as returning to a higher instance in a type instance tree, during top down design. This can hardly be dealed with, with a rendering technique, since it far more is dependable on a object grammar. However, non-photorealistic rendering is certainly a good way for approximating (ambiguing) a design for the reasons described before. - Ernst >SIGGRAPH 96 is the place to start for progressive meshes. > >Progressive Meshes by Hugues Hoppe >in: SIGGRAPH '96.
