It was my godson's 6th birthday yesterday, so I spent my lunch breaks for the
last week making him this birthday card.

The track is a mesh placed on a bezier spline (using Colefax's spline macro).
Cars are blobs.

He was rather happy with it, though I wish I'd had more time to work on the
background (and that shadow line artefact on the loop, doh!).

Nice scene, Tek. Very cheery :)

Hello,
Great scene!
Composition is wonderful and fog effect makes it even better.
I would like to let the fog stereoscopic like your image.
I love the audience very much either. They are abstract simply modeled, but
how they looks lively! I think this impression came from their distribution
on the plaza below the circuit. Could I ask you if you allocated them
automatically?
Your scene refreshed and stimulated me. Thank you very much.

I think that the crowd was placed totaly randomly, with random rotation 
and colouring. It also seems that there was no real attempt at 
preventing collisions.
Not bad in this case, as the solliding spectators look as if they are 
hugging.

I am sorry for my bad english, I wanted to say:
Could you please tell me if you allocated them
automatically?
Pardon.

Yes, I was captivated by them.
Also the crowd look avoiding shadow of the race course.
If they placed randomly as you say, or not, really pretty
presentment.
Thank you very much.

Yeah the crowd's placed randomly. I used a radial placement like this:
#local rs = seed(2211);
#local DISTRIBUTION = .7;
#local RADIUS = 50;
vrotate(x*pow(rand(rs),DISTRIBUTION)*RADIUS,360*y*rand(rs))

So they're laid out in a circle, with a slightly higher density in the middle
than on the edge (if you set DISTRIBUTION to .5 the density becomes roughly
even, higher values concentrate more in the middle, lower concentrate more at
the edge). I placed the circle so it would be concentric with the curve of the
track in the foreground, so nobody would stand under the track.

As Alain said, the fact that they overlap is an obvious symptom of automated
random placement. If I placed them by hand I wouldn't have overlapped any.

Hello,
Thank you very much to share your idea.
Your explications made me sense and I found the circular edge of the crowd at
last.
How I surprised to know what the two story park means! What a powerful disguise.
Your scene is full of inspirations.
Thank you very much again.
