Erlik, thanks very much for these programs! Went off and downloaded CityGen and Poseray right away. I played with Citygen and exported a .pov file. Ran Poseray and tried to import the .pov file so that I could export out as an .obj file to Bryce. Poseray could not import the .pov file from Citygen. Error messages came up saying file has no vertices and file has no faces. I believe that the .pov file saved by Citygen is an ascii file and not a binary and therefore Poseray does not recognize it. Do you know of any file conversion program that would convert a .pov ascii file to binary?
