Hi all,
I'd love to share some snapshots of my present work, which lasts for half a months and depends heavily on a modified version of osgShadow and the OSG effect compositor in developing. The scene is from part of a CBD area in Beijing, and it will be shown on a wall with four projectors at last. I use VDSM with additional PSSM support and customized shaders to provide real-time illumination and shadowing. And the compositor which is currently maintained in osgRecipes is used to add glow effect and final color grading. SilverLining SDK is used for sky and cloud rendering.
The scene includes only a few refined building models, but with OSG's dynamic paging ability we can easily support very large city with nearly the same rendering quality. I will be glad to submit both the shadow and compositor functionality to OSG core at the end of this year, or at the beginning of next year (as Robert is busy at present :-) and hope it could be improved again and again and also help other develop their applications.
Current city models may not be suitable for open source use so I may have to find and commit a copyleft set of models along with the coming submissions. It would be appreciated if somebody could provide me some at that time.
Cheers,
Wang Rui

Hi,
Congratulations, this is looking really good!
I am also building a city model, but on a much smaller scale - it is used in a radio simulation of 4G networks. I have recently added Silver Lining for sky and clouds, shadow mapping (the very basic algorithm), some water and reflections of buildings in the water.
The speciality in my implementation is the rapid passage of time, which is accelerated by a factor of 500. People will turn the lights on in the evening and early morning, and off at night time.
I learned a lot of techniques from your book, so keep writing them ;)

A snapshot of my version of Chicago at dawn. You might ask yourself what that cruise ship is doing there.

Only a few detailed 3D models are in the city (imported from Collada format), the other buildings are vertically extruded ground shapes. The ground looks so strange because it displays radio coverage by radio cell.
