I'm building a GEM patch with some kinematics
simulation (like gravity,
inertia, collisions
I've done some pd abstractions to simulate mass, spring, damping and strength. You can find them inside the xgui distribution. http://dh7.free.fr
For eg.: You just connect a strength to a spring and then his size is changing ! if you connect 2 strength, the strengths will add themselves and the spring will change is size in consequence.
BUT it's only 2d...
Cheers, Damien.
