Vortex simulation of the cable

Hello!
Im using Vortex with CoppeliaSim to simulate my scene:

With Newton cable behaves good. And the same setup with Vortex looks like on this screenshot:
Have you any idea why is it so? Also I followed the dynamical simulations advises from coppelia
Thank you in advance for your help

Hello,
I am not sure I understand why you created such a complicated cable construction with loop closure constraints...
Why not simply doing:
Code: Select all
cylinder --> revoluteJoint --> sphere --> revoluteJoint --> cylinder --> revoluteJoint --> etc.
You'll have to make sure of course that adjacent shapes have local respondable masks that do not collide.
Have also a look at the demo scene in
scenes/otherScenes/ropeTest.ttt
Cheers

Hello, thanks for the example. But your example behaves much less realistic then mine. In spherical joint i cant use mass dumper spring control which is mandatory in order to simulate a realistic cable (which has a mass, extensible and bendable with some effort). May be you have some more examples of cables with mass dumper spring mode?

You actually have many different ways you can create a cable or cable-like model. My point was more about: why do you use so many dummy-dummy overlap constraints for your cable, and not simply a single chain of objects (shapes and joints)?
