Got a baby about to tear apart the computer area, so no comment for
now...

Nifty.  Following the winning car was a necessity I suppose  :-)
Just think how easy this same thing would be as a program instead of a ray
trace, in fact that makes me think you ought to be doing Quality=0 for these
animations.  Would improve render times incredibly.  Maybe it's not too slow
to parse and render as is though?
People are going to be asking for this to be faster on the track anyhow.

What a rip-off! Where are the crashes and firey explosions? :)

It would be too hard for me to write any kind of program that could do trace
calls on rotated and translated boxes. ;) There are trace calls to decide
whether to brake/accelerate and which direction to steer.


I need that many frames to make smooth and really intelligent (crash-free)

when making this anim because people thought the first version was too slow:
perhaps I should display every 4th?

When I did my flocking anims with 100 particles, that crept along really

only make 6-10 trace calls per actor per frame.

You want crashes?: I have about 30-50 earlier versions of this with

of the actors and then allow for a crash, where the car just stops there
in the middle of the track.

But it was a real accomplishment to get them to go this fast without
crashes, even if they would rather slow down and hug the wall to let the

set of parameters (brake/accel decisions, etc.) that would prevent


/slow down (how many frames before wall collision it would tolerate
before braking.)

BTW if there is a big interest in this, I can make a self-explanatory
page like I did for boids....

Fiiire! Fiiire! 8-D

I'm interested in seeing this stuff, not really doing it myself. I'm sure
others would be, so make it anyway.

No, blend every 5 frames together to do motion blur and then put that
together and post it.
