Some weeks ago I heard about some Clutter() macro. Since I found nothing
that kind (to be honest I didn't even look for it...;)) today I wrote (after
lunch) a little macro which randomly places a series of objects. It allows
you to define obstacles as well (as you can see from this simple picture).
There are 275 spheres and 275 boxes randomly placed in a 10x10 square. The
torus is a *no fly zone*.
Comments are welcome.

That may have been me, in jest, suggesting that mega-pov needs a clutter().
pretty nice tho :)

Even more clutter for this one: 2500 objects.
Time for parse: 40 min (!)
Time for trace: 1 min 20 s

Looks quite useful, something in the same direction but probably more
universal (although it seems quite complicated in syntax from what i have
seen):
http://www.ksp.sk/~dushan/dipl.php
I don't recall this being metioned in p.u.p. or somewhere else in these
newsgroups before so some might find it interesting to try.
All such things could extremely profit from a refer{} patch like ABX seems
to be working on.

It looks cool and good, altought I liked also the brown boxes - they
looked very real and somehow like something I would like to eat.

It looks really interesting to me, though rather complex.
The macro I wrote is intended to serve my poor needs: I got bored placing
every single object on a table (like in my last IRTC entry). So I just wrote
a little (and extremely simple) script that places any objects (the number
is unlimited) in a rectangle. The placing is absolutely random. So, if there
are too many objects and too little space the computer spends a lot of time
to find free spots. Because it just verifies, each time, if a random
position doesn't touch any object already placed (and the obstacles as
well).
If anyone is interested in it, I can post it.
Regards,
Jonathan.

I'd be very interested. I did something similar a while ago, but used an
external
program. Would love to see your code.

detection with my own little random placement method via imagemaps.
My own ideas are really complicate to realize and I would love to see a
simple way.

How about a probability map? The macro takes a function that defines
unique probability for each point in the area. This way the map could
be defined by a mathematical expression or grayscale image.
