The questions are: which codebases do we use? How clean is the code and how active is the community?
In general we should be looking for the biggest community. The one with 2x as many developers will win, unless both have achieved critical mass.
Any codebases we use we will want to be able to program in a Mono language. (Reasons for this do not fit into the margin) Finding managed bindings is a part of the development, and they are all out there, except for the driving logic, which is in progress.
GNU Scientific Library
All C, but so big it gets its own section: http://www.gnu.org/software/gsl/
We could use this code as a source for us.
Math (Jeko or Wolf-Dieter)
Here is a set of math functions that the torcs robot needs. http://keithcu.com/wiki/index.php/Image:Unitlinalg.cpp
We also need support for splines.
Note it doesn't use operators, and our code should to look much nicer.
We should be binary compatible with torcs, but we can change it to match our data structures.
AForge AI Library written in C# Math, Image processing, neural networks, machine learning, and vision. There is a decent amount of traffic on the forums, and the releases have thousands of downloads. The guy is from Latvia and has linked-in profile says he is looking for consulting work: http://www.linkedin.com/pub/4/410/A72

Found a .Net wrapper! http://code.google.com/p/opencvdotnet/
Intel's code written in C++ in 1999-2000. Not too much going on with it, but it was used by Stanford in the Darpa Grand Challenge. It has code that should be thrown away, but it is comprehensive. I think we should start with it, especially that there is a .Net wrapper
Great background doc, with lots of links: http://www.red3d.com/cwr/steer/ (PDF is in mercurial repo)

The various engines in Torcs (from Wolf Dieter)
The "delphin V1.00" is the easiest to understand one, drives stable and can be extended by others without great initial training. It consumes litte simulation time and initializes very fast.
The "ModBod" (also written in Delphi) drives faster and uses a precalculated racingline beeing alone, but switches to the delphin-mode in traffic. Extending it would take more time to learn about how it works. (It was used last year to prepare the races for the wdbee_2007, written in C++, only reading the modbot information and driving while racing) Consumes litte simulation time but takes some time to initialize the racingline.
The new "Simplix"(="Wdbee") (written in C++) is the top of the art robot (See the results of the Forza race at the TORCS Racing board: http://www.berniw.org/trb/events/event_view_result.php?raceid=64).
It drives very fast and uses three precalculated racinglines (One fast beeing alone, one at each side to avoid without reducing the speed more than needed). If pitting is used, there are six racinglines to get the fastest way in an off the pitlane too! But to precalculate the racinglines, it tooks a lot of time while initialization and it consumes much more simulation time!
(Jeko) Mono Tao Framework http://taoframework.com/
Ogre: http://www.ogre3d.org/ A good and popular one with a big online community. Used by many "serious" project, it is well documented. A friend of mine worked with and recommended it.
http://www.ogre3d.org/wiki/index.php/OgreDotNet (Supports mono, not that used)
http://www.ogre3d.org/wiki/index.php/MOGRE (Popular, doesn't support Mono)
I've been using openscenegraph for 2 years (that was 2 years ago) and it has been a pain! Lack of documentation and a few bugs. However it is quite popular, it is still not very mature. Its good points however: there are many import of 3D formats supported and it offer good real-time performances.

The physics engine we will use is likely this: http://www.ode.org/
There are .Net wrappers we will use so we can program in C#: (Jeko) http://sourceforge.net/projects/odedotnet
PDF intro: http://www.ode.org/slides/parc/dynamics.pdf
API overview: http://www.ode.org/ode-latest-userguide.html
(Jeko) We also need a physics simulator GUI to play and step through simulations. Here is a robot simulator: http://playerstage.sourceforge.net/index.php?src=gazebo
Can ODE help with this?
One thing that we can set up in the physics model is a degradation analysis of the ribbon. Essentially take the ribbon stretch it under high tension and then snap a thread. The interesting part is the stored energy and where it goes - there is a lot and it will affect how we design the ribbon.
http://www.racer.nl/, nice looking, source code available but not open source (restrictive license).
http://www.ultimatestunts.nl/, require art work to look better. The track format supports junctions.
Removed from consideration
All in C#, but going through a rewrite, and they don't have a community yet.
Delta 3-D http://www.delta3d.org/
PLIB, Portable game library: http://plib.sourceforge.net/whats_inside.html Features: sound effects, music, a complete 3D engine, font rendering, a simple Windowing library, a game scripting language, a GUI, networking, 3D math library and a collection of handy utility functions. Each library component is fairly independent of the others - so if you want to use SDL, GTK, GLUT, or FLTK instead of PLIB's 'PW' windowing library, you can.
This is a cool component for people making simple games, but we don't need most of it, and the stuff we do need isn't that powerful or popular. Torcs uses it, but that will change :-)
Irrlicht: http://irrlicht.sourceforge.net/, also has .Net bindings
Looks like a good engine, but some have complaints about it: it is less pluggable, less powerful, etc.
http://axiomengine.sourceforge.net/wiki/index.php/Main_Page This is a port of Ogre that is clean, rich, and supports Mono. It doesn't have the community of Ogre and Irrlicht. Using a native C# component is awesome, but using something with a community is more important.
This is missing a lot
