The default tree density in FlightGear materials is WAY lower than current PCs can handle.
I don't know whether the tree effect can be applied on objects
All in all we're still doing okay with FligthGear.

The scenery textures are still mediocre so covering them with as many trees as possible hide that a bit.

The user can configure the tree density in relation to the max tree density defined in the material.

- Buildings. As much effort as the osm2city project has done, our generic models for buildings are still low detailed. We might increase the detail of the generic buildings in osm2city, specially roofs.
- I don't know whether the tree effect can be applied on objects, not only materials. This way, osm2city can create pathways with trees. This is supported by the building map in materials, but the generic urban materials don't look very nice if real openstreetmap buildings are set on top. Another possible solution is that terragear creates shoulders along roads and rivers, with the necessary material to put trees/bushes on them. Or maybe this can be done with shaders, I don't know.

I just fetched the source and built and ran it. 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?
