Procedural create CityEngine, one of the few useful procedural urban tools around. Does this mean that they are looking for an easier way to create models of buildings? Reconstruction from street photographs? From aerial photographs? Why not from existing meshes (from video game artists)?
Image-based Street-side City Modeling (pdf) from Sigg09 shows some of the potential of this direction.
I'll be looking forward to seeing what these guys do next.
