Hi
I have a developed a manipulator like the one you want. It has some extra code 
specialized for my needs. Let me clean extra codes and send it to you. Maybe it 
can help.

hello,

I am after an osgManipulator with CAD style rotation. 
In a typical CAD program the rotation keeps the roll fixed and orbits around 
the centre of the screen.
In contrast the TrackballManipulator allows the roll to change and rotates 
around the origin.



Has anyone come across code that implements this type of rotation?

thanks,
Richard
