Flexible Objects Physics Simulation

A physics sim with flexible objects. Torii gradually fall into a rotating container, stopping at 40 total. Each one is modeled as a network of spring-connected point masses that has a thin polygonal skin used for collision detection. Each frame of the simulation proceeds in 2 steps: first, an ODE solver advances the positions/ velocities of the point masses using the spring forces and gravity... then collisions (in which the masses of one object find themselves inside the skin of another) are resolved (by moving the mass and altering its velocity by a bounce). With 40 objects, a frame of the sim takes about 1 second to compute on a 2006 vintage MacBook. Each object consists of about 200 point masses and 1000 springs.

hey, just curious what software did you use to build this simulation? (very cool, btw)

[benschaeffer]

I wrote the simulation code back in 1998, so it is a custom job. Glad you enjoyed it.

it looks yummy

[MisterSym]

Mmmmmmmmm.....donuts.....

[TacoPluss]

Soggy fruit loops? Ew.

[jeetendrag10acc2]

you should cook them a little longer.the dough is too soft,and you la have trouble putting n the ODE jelly.

donuuuuuuuuuuuuuuuuts!

[yayyayyay09]

I think they are called softbodies, and they look tasty XD

[MultiQuestionmark]

DONUTS!



[ThaOggeMan]

could be a little softer mesh but I like it

[jer3my95]

mmm gummy donuts lol

[2t22tornadosiren]

♫ Donuts from heaven...♫♪

Mmmm... donut...
