Hi,
It's normal for pbo-getOffset() to return a 0, and correct to pass
this to glTexSubImage2D, but only if a PBO is bound, if it isn't then
it will result in a seg fault. Perhaps there is some mistake in the
code that isn't binding the PBO when it should.
OK, I'll try to check this too.

I have a KeySwitchMatrixManipulator , which served as a swithcer between 2 MatrixManipulator : a default Trackball and a MatrixManipulator that I defined(bounding to a object)
Hi,
also have a look at these old emails. It is still something I want to
add to the manipulators to enable smooth switching between them.
Basically, the internal state of the manipulator is not fully encoded in

Hi,
you could also have a look at osg's AutoTransform that does it all for you.
