Pretty realistic sway! Impressive.

Cool. another cloth physics simulation

That's one stretchy piece of spandex! It would be interesting to try out different "fibers" which would be more or less likely to stretch versus tear, as well as wet and dry versions. Of course, that would also be a hell of a lot more programming.

Detach the points and hold down the down arrow key and you'll feel like you're watching a clothes dryer. Zippy the Pinhead approves. Anyway, second vote for different "fibers". And something to keep it from bouncing/jittering randomly on the ground when it should just be lying there still.

here's my not so polished example, complete with z-sorting errors. (hint: everything looks better as a wireframe..) source in as3 if anyone is interested.

Ah, constrained particles, is there anything you can't do?

localhuman, that's certainly a damn pretty one! Because of the pattern, it feels more like super-stretchy lace to me than spandex. It looks especially nice when you take one end and try to twirl it like a skipping rope.

Wow. This is cool. What's cooler is that we can play with it within an internet browser. 10 years ago that would have been unthinkable! I LOVE IT!

I tried tying it in a knot, but it doesn't have collision detection.

http://bullet.googlecode.com/files/Bullet-2.71-Demos-win32.zip Bullet physics engine demos (Windows, ~3mb). Run "ReleaseAllBulletDemos.exe" for more physics demos than you can shake a stick at. The 'SoftBody volume' demo is especially fun.

thanks a bunch maudlin, I've never really shown that at all because I'm pretty sure it sucks. ah well. anyways, the idea about making different kinds of fibers is interesting. Physics simulations can get kind of weird, and I remember lowering the gravity vector to make things less springy, but then things get all swimmy and not cool. I do really like the idea of making it tear-able, though, I may have to work that one out. I had been aiming at making a trampoline type game, but got side-tracked by that year, what was it? oh yeah, 2008.

Ha! localhuman, I just found out that it also makes an excellent, albeit frustrating, cat toy. There may be commercial applications for this little project.

I like the fan -- you can pretend you're drying off a superhero's cape...

Ah, constrained particles, is there anything you can't do? The answer, my friend, is blowin' in the wind.

The paper linked to from the post's link is really cool, and demonstrates a really neat idea that I wanted to do for my own physics engine, but wasn't sure how: make velocity implicit from where you are now and where you were last frame. This helps objects move more believably.

Cool, be nice if you could simulate the flutter of a flag though, it's missing that.

The advanced version has walls on all six sides. Inside, the cloth is simultaneously blowing and staying still, until we open the box and observe it.

be nice if you could simulate the flutter of a flag though, it's missing that. Rotate the cube so the fan is on the left. Move the pins to the left side of the cube. Turn on fan.

I can't fold sheets properly in sim, either, it seems.
