RigidBody Stacking Simulation

Hi all, I have been playing around with Kangaroo2 for a few weeks now and wondered if a simulation of a stack or pile of rigid bodies is possible using its engine. Right now, the only clue I have is modifying the solver threshold to a big number (1e-3) to stop the stack from moving, but the results are not the stack behaviour I was aiming for (see gif attached).
I know stacking physic simulations require a fairly complex engine, and I was wondering if Kangaroo 2 can support it anyhow.

You may want to try PhysX

I’ev had some pretty good results with it so far.

Hi Manuel,

Currently the rigid body collision does not include friction, so isn’t suitable for stacking. There’s an update to this for the next release though.


Is there a good way to simulate friction in Kangaroo? I’ve tried to mimic simulation such as the one you do with the plastic chair hitting the ground, but I was unable to simulate the friction that would occur when part of the chair hits the ground as it’s thrown laterally.

In this video, around the :03-:04 mark, you see the leg of the chair get caught on the ground. Is it friction that’s causing that?

Hi Matthew, Daniel and John,

Thank you for your fast answers. I used PhysX in a similar project in unity, (how wonderful it is to find it here in gh too!). I will give it a try. Thanks again!
