How do I plot an arrow with a length proportional to the magnitude of a force/torque that points along the force/torque

[TenguBoss]

Dear Colleagues,

I am having a blast with MuJoCo 3.1.1. Thank you, DeepMind and @yuvaltassa and your team!

I would like to visualize an external force applied to a body, a torque generated inside the body, etc. The best example is the contact force in the MuJoCo visualizer.

I have tried to implement the example found here https://www.roboti.us/forum/index.php?threads/visualize-programmed-perturbations.4091/ However, I am falling short of finding an object equivalent to viewer in the example.

I think I am missing something fundamental and I cannot find it in the documentation. Can you help me, please?

Season's greetings! and thank you!

It is called Perturb Force
