Hi all,
I've recently been experimenting with the cloth simulation theory found at
http://freespace.virgin.net/hugo.elias/
I'm planning on writing a POV macro that let's you drape a cloth over any
object, using the trace function. So far I've implemented the code in Visual
Basic, and made a small prog that outputs a bunch of triangles when done
simulating. The attached pic is a sample of what it produces. I know it's
not too pretty, but I just felt like posting something :)

You've obviously had better luck than I did. I tried the same thing a couple of
months ago, but could never really get it right. I hope you post the code when
you get it finished.

That's impressive. I'd like to see where this goes.

You're taking your cloth simulation theories from the wrong place. I
seriously recommend you check out the work done by some french guys that
really improves on the description you see at Hugo Elias' site. The address
is: http://www-syntim.inria.fr/syntim/recherche/provot/index-eng.html Read
it. You will like it. :)

I certainly plan to, but my rather ambitious feature ideas could slow down
the process :/

Hey,
Cool, I can't wait to see how this project develops. I saw some cloth
simulations on TV about a year ago, and have always wondered how easy it
would be to do. I am interested in your picture that the image isn't totally
symetrical. What introduced the randomness in the way the cloth hangs? I
would have though that a computer simulation would have been too "perfect",
but I am pleased to see that it isn't.
Keep up the good work,
Equiprawn

I have to admit that I'm not sure, but it might be that the cloth isn't
perfectly cenetered on the box.

I would have liked it more if any of the images had loaded :(
Thanks for the link though, I will check out the document he'd put up.

Very nice. This could be interesting if it is incorporated into the Spray
macro so that water that falls onto something do a little more than just
puddle.
Just an idea :)

This is amazing for the modeling aspect. I read through his pages, but I didn't
catch where to stop the iterations to say "this is where the damn thing lies."
How did you determine when the process was done?

Great! I'm impatient to see the result.
Have you seen the 3 animations of Magnussen based on the theory of
Hugo-Elias?

Well, Hugo suggests that some randomness is introduced in the
tangential forces of threads and in thread density as well. If you
followed his algorithms closely enough this should account for the
randomness. Cloth simulation is a chaotic problem so even the
slightest change somewhere can change output dramatically.

The program I wrote shows a top-down view of the cloth, so when the cloth
didn't seem to move much anymore, I just stopped the simulation, and dumped
the triangle data. For the macro I will probably write some code that checks
when the total movement of all the nodes go below a certain(adjustable)
threshold, and then stop the simulation.

Very nice. But for you and all others (since I thought I had
seen this before), have a look at:
http://www.realflow.com/gallery.html
and scroll down until you reach "Elastic Particles".
This does not mean, that the other animations aren't
interesting.... It just fits.
