Description
Use the GNU GPL PixelCity project to create autogen support for FlightGear, to dynamically create cities for populating the FlightGear scenery procedurally.
PixelCity is at the moment C++ code that uses pure OpenGL with a fixed rendering pipeline (i.e. no shaders).
There is a blog column providing in-depth details about the implementation of PixelCity: http://www.shamusyoung.com/twentysidedtale/?p=2940

Code
Official repositories:
Originally, PixelCity only built on Windows, but there are now a number of ports available:
Porting
- It really looks cool from the distance and close up.
- Implementing it into FlightGear requires porting the OpenGL calls to be OpenSceneGraph compatible, probably by implementing osgDrawable.
- The current implementation only shows night-time views, so this has to be tweaked, too.
- Another issue to take care of is interaction with existing scenery models, so the generated buildings do not interfere with our scenery models.
- The same is true for our landcover, roads and elevation data.
- Definitely worth some thinking. Probably as a google summer of code http://wiki.flightgear.org/index.php/GSoC project?
- Perhaps something using blended cities?
- You could input a street map and it would only build buildings in the lots, not on the roads.
- Now, maybe combine that with open street map or something?
- Also, you could then just load it fairly normally into flightgear.
- Instead of downloading the building, it could be an option to download the files needed to make it and do it yourself.
