How to add angular velocity to a soft body

[iwg_eric]

I've recently converted my rigid body to a soft body. With my rigid body, I would use body->setAngularVelocity(btVector3 angularVelocity); to add spin to the rigid body. Is there a similar method to add spin to a soft body?

Not that I'm aware of. Implementing certain rigid body features like that is much more complicated for soft bodies, which essentially have separate transforms/velocities for ever node, and a dynamic centre (of mass). Offhand I'm not sure how you'd go about mimicking that functionality for a soft body.

there's no such thing for soft bodies...
in our implementation you can apply velocities by calculating
the proper velocity for each node in the soft body.
it's not a one line thing but still pretty easy/fast to implement

Thanks for the feedback. It seems to be working by crossing the angular velocity I want to add by each nodes relative position and adding the result to each node.

Hi,
I obtained torque on a soft body by applying an clusterVAImpulse for every cluster of the soft body
