You're absolutely right, thanks.

Right.

[SOLUTION]
Ok, problem has been solved: I de-activated using "ATI/AMD proprietary
FGLRX graphics driver" and re-installed mesa-components, rebooted and
then glxgears as well as some of the pydy/examples-files runs great!

Both the pendulum examples work great in 3D. However, as an example -
the "Rolling disc" runs maybe 2-3 frames and stops within 0.5 seconds
and hangs the window so I have to force quit/close it... I don't have
any idea about where to locate the cause of this problem...


BTW: Now where at least the pendulum examples (single+double) work
fully in 3D, I'll tell you that I want to learn more about multibody
modelling. I want to model a gearbox / drivetrain in a windturbine.
I'm starting to learn from this book: "Computer-Aided Analysis of
Mechanical Systems" (can be downloaded for free) by Parviz E.
Nikravesh and thats how I came around pydy... Is pydy suitable
for that kind of modelling and is it made in a way similar to
that described by Nikravesh ?

(btw no2: I've now disabled to receive mails in digest mode, because
I can see that the group forum software doesn't organize my mails
based on content with the same subject-line... My next replies should
hopefully be in the correct thread, when I just reply to it instead
of making a new email everytime)
