I have a rigid body rotating in 3D space. I have a torque vector that I want to apply to the rotating body over a given time step. What I want to know is, will the torque be enough to stop the body rotating on any of its axis and reverse direction, and, if so, exactly what would the torque vector be to stop the rotation instead of reverse it. The angular velocity is known, and the inertia tensor is known, so I am calculating the angular momentum as I * w.
The background to this is that I'm simulating the friction of a particular point on a body in space, and often times the torque created by the friction is more than adequate to stop the body from rotating, and if I apply the full friction-caused torque to the body, it actually rotates in the opposite direction, when what I really want to do is simply stop the rotation.
