How to get forces between rigid bodies in blender

Ehsanizadi · December 20, 2013, 2:14am

Hey,

Is there any way to get forces between rigid bodies in blender?
For instance how much force is acted by one rigid body to another.
Or just suppose you have a mass of cobbles and you pour them on a floor (passive plane), I am interested to see the forces these cobbles impose on the floor in different time steps.

Thank you in advance.
Kind regards,
Ehsan

Any help???
Any clues?

I don’t think that’s easily possible. Bullet (The Physics Simulator) does not expose those kind of data as far as i know.

Actually, I already know that Bullet does expose such data.

Are you absolutely sure? There is a similar function being developed for the Game Engine, getReactionForce()

As far as I know, there is no such function in the standard render branch - I hope I’m wrong though.

I think you might have to construct a measurement rig to extract that kind of data.

Could you explain it more?
Is it possible to include it in one of the sub-menus of of blender by manipulating of python code? if so, how?
I am new to this, any tutorial/sample of this kind would be very helpful to me.
