Hi, I'm going to post my current progress in the addition of "wrinkliness"
and air interaction with my cloth.

The cloth has approximately 7200 smooth_triangles, and they are generated
with a program I wrote in C, which makes all the simulation. I've found this
to be a great way to enable some parallelization, as I put my brother's
computer to run this program and my computer does the rendering.

I am still not satisfied with the air resistance. I believe it is still too
soft. I may add some wind soon.

Yesterday I saw Andrew Cocker's cloth simulations (posts are around
May/2001) for first time and was completely impressed. Now I have a very
difficult standard to meet!!!

Well, I hope you like it and would love to receive any
comments/suggestions...

Fernando.

my my my... wow...   <applause>  I like that.  Is are you working
on integrating this eventually to be usable pretty simply into
POV or is this a rather specialized app. for your own use?

Hi Fernando,

this looks absolutely awesome, very realistic!
one can almost feel the structural properties
of the cloth.

there's just one thing that i would improve:
the folds of the cloth suggest that it is very thin
and fine, like silk for example, but the big fold
from the sphere to the front-left corner of the
cloth is goffering (i hope this is the right word)
a bit abruptly and disjointed. it should fold more
smoothly to underline the material.
But that's just a minor thing.

Keep on clothing ; )

Thanks for the compliments Fernando, although I feel that your efforts are
better than mine in as much that you have written your own code, whereas I
simply utilised ClothSim :-) . Keep up the good work.

All the best,

Andrew Cocker

Wow! Looks great! 
This brings a bit "life" into cold (or should I say cool!?) Pov!

Go on!

Thanks Peter! I still don't have plans for that... Right now I am just doing
it for the extreme pleasure derived from trying to simulate real physical
phenomena :)

I believe it would involve some work to make this a generalized and friendly
application, but if I do so, I'll let you know.

Thank you very much for your comments! I'm very glad you liked it!

Fernando.

Thank you Thies! I'm very glad you've found it realistic! I'm still not very
happy with the air resistance, but I'm still working on it!

You're right, it's meant to simulate a very thin, feeble and flexible cloth.
I'm right now experimenting with a more robust-like and a bit stiffer cloth.
I had great results with those new settings, but on the final frames I saw a
very strange behaviour, so I won't post it until I try to solve that.

About your suggestion, I didn't understand you very well about the
"goffering"... I know it is difficult to describe such things... I don't
know if you can describe it in another way?

Thank you again for your lauds,


Mexico City, Mexico.

Thank you Sebastian! I always enjoy, as everyone else here, trying to
simulate real things. Many people don't understand it, they say that we
already have the real thing, then why simulate it?


useful, but because they find pleasure in doing so, and they find pleasure
because it nature is beautiful.".

Thanks again for your comments Sebastian!

Well, I'm greatly honored to be complimented by an expert! :)

Thank you,
