That's all really excellent stuff. I totally agree with moving in that direction! Some thoughts: 1) a better track editor/format would make this easier, 2) some code work will be needed to optimize for the case of a bunch of instances of meshes -- but I needed to touch up the scene graph system anyway.

What is the license status of our tracks? I could extract the objects and set up a library. If we assign some mass to the objects, we would have dynamic collisions with track geometry(tire barriers).

There's some license information in the about.txt files in the track folders. Most are used with permission without any copyleft licensing, Rouen is public domain so that'd be the best place to pull out some objects and textures. The TORCS project is another good source.

What is your pixel color equation(E_l * Lambert * BRDF + ambient)?

I propose this:

Code:

sum_over_lights(E_l * Lambert * BRDF) + ambient_reflection + ambient_irradience
