Angle Between two objects.

I have two obejects connected by a NXD6JointDesc. They rotate like a wheel. I would like to get the angle of the rotation... What is the easy way to do ? Is It possible to get the information from the joint ?

- After that I would like to setup the angle during the simulation. Is it possible ?
Thank for your answer.

no idea. I use NXD6Joint for this. Is this help you to get me an answer ?

I can't give you an exact answer but I think you would need to get the global orientation of each object and then do some calculation to get the angle between them, I don't know the calculation off the top of my head but you could try looking here...

I am ok with your answer but how it is possible to change the angle on the joint after that ?
