Implementing a mass spring system with volume constraints in physx

Omniverse General Discussion

Hi All,

I have the following questions wrt physx capabilities:

  1. How can we implement a mass spring system, eg. a cube structure with all edges of the cube represented as springs and corners as point masses.
  2. How might we impose volume constraints on the cube? (to prevent shape inversions).
  3. How can we change the lengths of the spring (ie apply actuation - compressing/expanding a spring through user controls).

Thanks!

Sorry. I asked the devs. Let me ask again. My apologies. I am on it.

Hey Richard, All! Appreciate any pointers on this, while it seems possible to do 1/3 (using say joints+rigid body spheres?), any pointers on 2?

I am trying to find someone to help. Sorry.
