Looks great - could you get the camera to follow the cloth and always have
said cloth filling a proportion of the viewing area (auto zoom) ?

Have you considered trying to form a sale with your system?

Yes and no :)
I've already deleted the mesh files, so I would have to re-simulate
everything, but in theory it shouldn't be difficult at all to position the
camera wherever we want.
Thanks for your comments,
Fernando.

I think I will need some help from someone from India... I know almost
nothing about flying carpet dynamics...
Ha ha ha...

I think you tried to say "sail"...
No, I hadn't considered that application... But it's a very good idea!
Actually I've been thinking on implementing what other have already done
here: make "gelatin" objects. However, my studies haven't let me do too much
in these days and I don't think the work load will diminish in the near
future :(
Good luck,
Fernando.

[giggles] Waaaay... that's really cool! In fact, that's fantastic! 8-D I
don't know what's so amusing about it... but you've really made me smile. It
looks really real!

I guess you have to consider what sort of sail you want to simulate. Or
even a whole boat! :)
Strength/angle of the wind and where the material is constrained by sheets
or halyards etc. Would be an interesting project! :)
Would be nice to see the wind fill a set of sails and see them luffing in
tacks etc.
You may even be able to sell the code to VirtualSpectator or someone.
