Back to doing graphics again. Eric might be interested in the Virtual Terrain Project, libraries for managing and displaying terrain and geographical data in 3d, and, among other libraries, that depends on the OpenSceneGraph code.
One question, since I haven't worked in real-time 3d in so long: A lot of people are talking about Z-buffer issues. One of the advantages of a "Quake" style renderer was that it was really pixel bound rather than polygon bound, and I've long (ie: 5 or 6 years) thought that the next logical step was to take all static data and do visibility culling and clipping using a variant of those algorithms. It doesn't solve all of the problems (ie: intersections), but since for most of the problems in geographic data we can easily resolve sort order I'm intrigued by this.
