When it comes time to build some 3D models of
cars and things, I should be able to help a lot.

But none of his runs use high fidelity in _everything_, just in aero.
For instance, he'll "trim" the vehicle and maybe guess at
the control surface moments to do that. But he'll use a constant
CG location. By the time he's done, the size of the vehicle
will have changed. He doesn't know yet that the force
required is beyond the machines capacity.
That's the flight control groups simulation.
Each little group has it's own major interest. Each simulation
in turn concentrates on and tests different things. They take
the "summary" analysis (expressed in tables, etc.) of the
other groups and add their own area of high fidelity to the mix.
So by the time you get aero, mass properties, trajectories,
flight control gains, etc., etc., all working in a realtime simulation
to, for instance, test the flight computer, almost every subsystem
is modeled heavily using tables of results at their core.
Tire models may use analytic equations rather than tables,
but those equations are just fits to tables of spotty experimental
values and probably extrapolate pretty far afield from the data
anyway. ;)
Tables are good, tables are cool.
So build up some fast table look up (TLU) routines
for your sim! :)

What about using neural network for the AI?
That way the AI will learn the tracks to know just like a normal
player, and it will interact with others just like the players.
Even though I don't know any C++, I know a god deal about java and I'm
willing to contribute with some NN code. Using java for the
multiplayer code is a good idea as well. Q3 does.(I think...)

Didn't SODA learn the tracks created by the player? Sometimes it took a
long time on a slow computer, but I thought this was a tidy bit of
programming.

I downloaded the java.sun.com SDK and it looks powerful in the graphics
area :-) I'm not sure how fast it is though. What is your opinion on
speed with Java or Borland C++ or Linux G++?
I don't know what Q3 uses, I'm a Tribes player :-)

I don't think this project will put you out of business ;-) It will give
those who participate a place to use some of these ideas that we always
thought about but never started :-D It's is the year 2000 after all, time
for a change :-)

Wouldn't that be great! Someone comes up with a new track. You install
it on your system and then, while you're trying to figure out the best
line, speed etc you find the AI drivers out there doing the same. Can't
see it happening like this, but it would be nice. :-)

No person's opinions can be said to be
more correct than another's, because each is
the sole judge of his or her own experience.
