I hope this is small enough to fit. I have a question about object
patterns that is related to this over in the newusers area. I still
need to add the permanent white lines on the trail that are fixed
in space and the flashing white spokes in the tires but it's looking
better then I expected at this stage. Comments, tips, suggestions
are all welcome. I've still got so much to learn...
I hope you enjoy...
Carl
p.s. I had to cut this back to 63 colors to get it to fit. My 127
color version at 770,071 bytes came back saying it was too
big.

to enable accurate detailing, as i watch it, the car seems to from start
do , a right turn, a left turn, a second left turn and then ends with
space/ displacement in the loop
just prior to the right turn, the tail effect seems to fragment
after the first left, i see a triangular shaped shadow, which i
undersand, on the second left turn there appears a darker red triangle
which i dont follow, unless you have another light source that causes it
anyway i could leave it running in lieu of a screen saver, been watching
for 10mins do :-)
wish i knew more

Yes... its just a 4 second animation looped. This is still very much
a work in progress. There is a higher quality one posted here:
http://www.tron-sector.com/forums/default.aspx?do=top&id=274417
along with some more info.

Yes... there are a total of 4 light sources in this scene.
light_source {<4000,6000,-6000> White}
light_source {<-60000,30000,10000> 0.5*White}
light_source {<-5000,9000,-6000> 0.7*White}
light_source {<-60000,70000,-15000> 0.3*White}
In the link above I talk about game grid units.
1 game grid unit = 100 POV-Ray units.
The grid itself is this:
#declare Foo = function
{min(abs(x)-int(abs(x)),abs(z)-int(abs(z)),1-(abs(x)-int(abs(x))),1-(abs(z)-
int(abs(z))))}
#declare grid = plane {y, 0
pigment {
function { Foo(x, y, z) }
color_map {
[0 color White]
[0.01 color White]
[0.02 rgb <0, 0.05, 0>]
[0.98 rgb <0,0.05, 0>]
[0.99 color White]
[1 color White]
}
scale 500
}
normal { bumps 0.01 scale 30 }
finish {
ambient .1
diffuse .5
reflection .55
specular 1
phong 1
}
}

Thanks... I can do better. I'm still trying to add the lines to the
tail. Check out what I tried to do over in the newusers area and
let me know if you have any ideas.

Did I answer all your questions?

Car?!
Can it be there's someone in the universe who has not seen Tron?
Animation looks pretty good but I suggest posting mpegs so you can show us
longer smoother animations without needing a massive file size.
Also, I'm not certain, but didn't the bikes in the movie have a little more
animation when they cornered (I thought they leant slightly before turning)? I
don't have my DVD to hand so I can't check.
The tail looks nice, it's one of my pet hates about the game Tron 2.0 is they
used a crappy little texture for that so it looked totally wrong close up, but
yours looks nice :)

I just got Animation Shop 3 and I'm still learning the ropes. When
I get serious with multiple bikes and moving camera I'll do my best to
make it a nice mpeg. This was just a test of the leading trail effect to
see if it worked or not and I liked it enough I wanted to share.

Off the game grid where they don't leave the light trails and aren't
making 90 degree turns, they do lean into the the turns but I'm
almost certain they don't on the game grid. If they were to lean,
how would you match the light trail up with the rear tire?
There are some Light Cycle games out there that do have a leaning
effect in them though. That may be what you are thinking of.
There are two other effects I've left out of this one. In the movie
they simulated the wheels rotating by having a spoke in each wheel
that was fixed in place but flashed on/off from one frame to the next.
White lines that were fixed in place where also added to the trail
as it grew to help give that sence of motion. I've now got both of
these effects added in the latest test I just posted here:
http://www.tron-sector.com/forums/default.aspx?do=top&id=274417
> don't have my DVD to hand so I can't check.
I'll dig mine out too but I'm pretty sure there is no leaning on the
game grid.

Thanks. Mine is made using a spherical texture pattern centered
of the center of the rear wheel. I wasn't sure how to make the
effect perfectly vertical like in the movie and have it continue
around the corners and look right. Besides I sort of like them
better this way. Call it a little artistic license. One problem with
this effect though is if the bike ever traveled close enough to it's
own trail it with 'light up' the part of the trail that its traveling
next to in addition to the part that follows it. I'm applying this
spherical texture pattern to the whole object and the light trail
for any one bike is just one big object. Anyone have any
suggestions as to the best way to fix that and allow a bike to
travel close to its own trail. I could break the animation up
and start it again with each bike having "old trail" and "new
trail" objects but my gut tells me there is a better solution then
that that wouldn't require me to manually piece together
different segments of the animation. The solution just hasn't
hit me yet.
Thanks,
Carl

Oh my god. GIF's are bad, bad! realy *bad* formats for animations.
USe always mpeg-1/mpeg-2 instead.

Animation Shop 3 is nice for post processing frames, but for mpeg
encoding I find tmpegenc hard to beat. I also use the plug-in
posted in the p.b.u newsgroup to allow it to work with PNG files
directly instead of BMP files. It saves a lot of disk space.

I second that, Tmpgenc is awesome!

Yeah, you're probably right. It was just a feeling I had.

Perhaps you could use uv_mapping on your texture, so it gets applied
2-dimensionally to the surface of the trail, instead of 3-dimensionally.

I liked it -- I would like to see a smooth MPEG-1 version though ;-)
Also, as I remember in the movie, the light trails did not reflect. If you
could make the light trails non-reflective, a bit more ambient, and even
glow just a bit using atmospheric effects, it would be even better. Also,
less reflective on the floor less of the "normal" amount would make it look
a little better too. It's a little too watery and detracts from the bike
itself.. The walls around the arena also need textures and a few more bikes
would finish it off -- plus a switch in camera angles, sound -- this has
gotta be a fun one to work on, I'm gettin' excited just imagining it! Maybe
just a bit of tilt to the camera down would also enhance the animation.
In response to the thing about leaning, there are some scenes in there
showing the drivers leaning over to make the turns. It just happens really
fast. The bike must be just thin enough to navigate a sharp corner within
two walls.
