Jello

Hello people,
http://www.2roqsmuseum.net/Members/V3ga/P5/Jello/ is my latest work with Processing.
This is some particles physics simulation with 2 types of constraints : inner constraints ( between particles ) and world constraints.
The process to update particles'state (position) is made through verlet integrator, which is known to be a stable integrator. The constraints are resolved using a relaxation loop, the soft ("jello") effect is achieved by allowing original constraints to be restored by a certain amount over time.
All of this is fully described in http://www.ioi.dk/Homepages/thomasj/publications/gdc2001.htm, which I had already used in a previous Applet ("SodaTry")
I'm planning to release another version of this in the near future , with perhaps friction with environment(the object will not slide when at "rest"), better rendering  , and more constraints to achieve better jello stuff.
Cheers

This is pretty funny. Is this some kind of remake of your Disco Cubizm piece?

Yes, this is the same stuff which is behind Disco Cubizm, except it was dirty lingo

Really nice. Don't suppose you could pick up the jello with the mouse rather than spinning the box?

Well, why not? But it would have taken a little extra effort to code a ray-triangle collider to pick up an object on screen. I had thought of making a 3D object picker with Proce55ing, but unfortunately, I don't know how to access camera matrix to compute needed things to perform such calculations.

This is a beautiful app!
for fun, change the sphere size, at 130 it spins on its own, at 140 it starts to warp, and at 150 it self-destructs. At 300 it looks like the Guggenheim in Bilbao.
