Hey Everyone,  
I was wondering if anyone knew of an existing implementation for an arcball-style mouse control in papervision for rotating an object? Or some useful advice for doing it myself?  
I can’t seem to find one so I suppose Ima have to go through the hell of doing it myself…■■■■ quaternions.

Also, does it HAVE to control the camera, or can I make it simply rotate the object instead? It would just be a matter of applying the transform matrix to the object instead of the camera right?

Thanks in advance for any help.
