opensource clothsim (freecloth), version 0.7.1

Postby chimera » Sat Dec 13, 2003 12:44 pm

hi guys
yesterday eve I tried (once more :) ) topixcloth. I really think this is a nice plugin, but nothing for real clothsimulation. so I opened mozilla to search a opensource cloth sim. now this is what if found.

http://www.freecloth.enigmati.ca/, it looks good, has a documentation and stuff. please take a look at it and tell me what you think. would it be possible to:

a) "plugin" it to blender?
b) integrate it into blender?

thx for replies. cu

Come on you coders, Take look Please :D

Seems very impressive judging from the mpegs on the site! Would be very nice to have integrated!

blendermax. I planed to post this on elysiun but I saw your topic. maybe this is because you posted it in "news". this just does not fit it.

I post my feature-ideas on blender.org.

here's a quote from his website...

"If you are interested in hiring me to write such a plugin, please contact me"

I think we all just need to step up to the plate with a few bucks and get the guy to do it. He'd probably be the best person for the task since he knows the source inside and out. It worked for Blender and it can work for this. Now someone just has to buy the source for a decent image editor. :D (don't get me started on the GIMP :roll: )

here's the answer from drpritch I got today:
It's a good idea, and it wouldn't necessarily be too tough to do, but I don't
have time to do it myself. I've long thought that Blender integration would
be a useful feature, but (again) my time is sadly limited. If anyone wants to
give it a shot, I can give them some support, but that's as much as I can offer.
The main difficulties will be a) coming up with a user interface and b) converting
between Freecloth's data formats (meshes etc.) and Blender's formats.


what do you think. shall we buildup a coderteam? -> I can lead the team, but I do not know very much c. All I ever did was i=a+b ;).

On a cursory glance, it seems like there is a limitation on topology for the cloth mesh- It has to have a disc topology, i.e. surface, no holes. you couldn't make a cloth tube for instance.
To be sure, this is interesting enough for drapes, sheets, curtains, tablecloths. However, to do clothes with it you'd need more topology support, or a 'stitch' capablity (it looks like it has the capability to constrain points, perhaps this could be used)
I think a python plugin is the way to go for this one.

I think a plugin for freecloth would be highly worthwhile, both for blender and freecloth. the site says that its a work in progress, and not yet ready for end users; it also says that the library aims at a full, usable and even, superior implementation.
doing a plugin for blender would open the avenue for user feedback, as well as allow those users to do *some* cloth effects in blender right now.

I'm personally interested in cloth dynamics being implemented in Blender. As a non-coder the best I can contribute is this series of links :

General Information

Cloth Simulation Links
http://www.cs.ucl.ac.uk/research/vr/Pro ... _links.htm

Physically Based Model of Cloth Draping (basics)
http://members.shaw.ca/chahal/clothpaper.htm

Simulating Cloth for 3D Games
http://www.intel.com/cd/ids/developer/a ... /20413.htm

Realtime Cloth Simulation
(also hair and water dynamics, source not yet available, not updated in a year)
http://christophe.tornieri.free.fr/Pages/home.html


Source Code

SimCloth3 plugin for discreet 3dsmax (with source, GPL)
http://www.chaosgroup.com/software/simcloth3/index.html

Topix Cloth Softimage Plugin
(with source, the original source of our own cloth script, has many features not yet implemented in our script)
http://www.topix.com/cloth/

Basic OpenGL based Cloth Simulation
(with source, supposedly buggy code, non-commented)
http://clothsim.tripod.com/

Apocalyx Game Engine with basic Cloth Simulation (with source)
http://apocalyx.sourceforge.net/

Clothray POVray patch (with source)
http://tofbouf.free.fr/clothray/index_en.html

http://www.reyesworks.com/
This site is no longer online. It was a project by Reyes Infografica (makers of ClothReyes) to Open Source all their code and integrate it into one large 3D project. Details on what happend to these plans are sparse ... anyone know any details?


Things to Aspire to

Syflex - The Cloth Simulator
(commercial product, used in Final fantasy Movie, XMen2 - supposedly the ultimate in cloth simulation - 5 to 10 times faster than most of its peers)
http://www.syflex.biz/


Hope this is helpful to those who would like to code this feature into Blender. There seem to be quite a few open source options to choose from. This is just what I found after an initial search. If I find any more, you will be the first to know.
