Nice Example Alan!

Haven't looked at Noel's take on this, but here's a dumb jiggly sphere
demo scene I did long ago for a friend who asked me about a
Verlet-based setup:
https://dl.dropboxusercontent.com/u/441883/xsi/ICE_verletJigglyBits_alan.scn
Hit Play and drag the null around, rotate or scale it.
/sphere_jiggly/ has a sim and a weightmap to define the jiggly zones.
Play with the VerletFramework compound's /Iterations/ slider (for
stiffness) and with gravity, damping and restitution force intensities
to adjust the "feel" of it. --- You can take off the gravity force if
you want, but I like it because when the character leans the fat still
droops downward.
/sphere_rigged/ has an envelope with one deformer to the controlling
null, meant to represent a rigged character. (If it's not obvious:
topo of both rigged and jiggly meshes must be identical in this setup.)
FYI, the more Iterations in the VerletFramework compound, the stiffer
the effect BUT also the slower the computation will be.
It could be more polished of course, but hey, it's pretty fast and it
works. :p

ps: I'll probably make this a TDSurvival tutorial at some point, also.

So here is a 2014 model working, just press play.
In fact i'm sorry i totally forgotted, i've altered the Andy
compounds to work with a moving object and a weight map.
you'll find the weight map part on the unsimulated animated
mesh... yes you need 2 mesh...

Hi,
Because i found the softimage verlet integration don't really
preserve volume, I recently used as a basis theses coumpounds
linked bellow.
This is verlet but simplified with a working volume
preservation as a simple spring system.
If you disconnect the collision part you'll normally end up
with a simple spring verlet system ;-)
