Bullet Physics, when to choose which DynamicsWorld?

I have a few general questions about the bullet physics library. Here is my current understanding in a nutshell: btDiscreteDynamicsWorld - Simplest physics world, only handles rigid bodies, maybe it has better performance. btSoftRigidDynamicsWorld - The only physics world that can work with large jello moulds btContinuousDynamicsWorld -...

How do you simulate a conveyor in bullet physics engine?

I am writing a simulation in which we need some boxes to be fairly accurately modeled as they move on a set of conveyors. Currently we detect if the box is colliding with the static conveyor surface and apply an impulse to each box according to what the conveyor speed is supposed to be. Is there a way to make the actual conveyor surface...
