[PyOpenGL-Users] Using Trackball

Is there any examples of how to use OpenGL.Trackball? All it says is
that you supply 2 points to the trackball, and then you use .matrix to
get the rotation matrix out.

But what points do you supply? Does it only rotate around the (0,0,0)
axis, so you need to do your own translations, etc? (I assume it has
to). At that point, when do you do the translation for an object?

Etc, etc. I've tried using it, but it usually looks really bad. Like it
will rotate, but it distorts the image as it goes, that sort of thing. I
haven't tried a lot lately, but I was hoping that I could have an
example to go off of.

Thanks,
John
