I've been doing quite a bit of reading, and I've been trying to get an intuitive sense of the constraints in play. Per the example of a holonomic function at http://en.wikipedia.org/wiki/Holonomic#Examples", I can intuitively understand that x^2+x^3 - L = 0 constrains a point to someplace on a...

Thanks for the link, I think that gives me a good idea where I need to start to understand them.

I'm working with a game physics engine that uses Jacobians to resolve contact forces. It's been a few years since my physics and linear algebra classes (where we didn't get to Jacobian matrices), so what I'm reading about Jacobians is fairly overwhelming. Most of what I can find are fairly...

Thanks for the reply. My problem is that I don't know how to determine if a given torque will stop the rotation over time. I understand how to find out the impulse to stop the rotation completely, but that's not what I necessarily want to do. I've got a torque that's working against the...

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...
