Moving linked objects

[hansE]

Hello, I am really new at 3D stuff.

Untill now I've done nearly all movement stuff on my own by directly Manipulation the positions of the objects.

But now I've encountered a new Problem and I don't now how to solve it.

As you can see in the attached Image, i have a Piston which changes ist length. This Change should cause the other object, linked with the pisten, to move. But because it rotates, the Piston also rotates.

My Problem know is, to move both objects dynamicaly, only by having the objects and the 3 Rotation Points.

I know how to calculate all the angles and so on if I have all lengths. But I am looking for a solution wich is capable of doing this on ist own.

Can Bullet (bulletsharp, because I am using C#) help me with this Problem, and how?

Thank you
hansE

For this problem the direct solution is both the fastest and most accurate. If you want to use bullet though, you can switch to one of the MLCP solvers and use hinge and slider joints with no problems (other than slow simulation)
