Hello all,
 
My understanding of PAT's is that they are groupings inside which all objects 
are in a separate coordinate system different from the rest of the scene. 
Should the PAT be placed at the root's (0, 0, 0), then its separate coordinate 
system coincides with the world coordinate system, but if it were to be moved 
around the scene using setPosition(), then the two coordinate systems diverge. 
Despite this divergence, objects inside the PAT will maintain their absolute 
coordinates, so an object that has position (x, y, z) inside the PAT will 
maintain that position no matter where we place the PAT itself. Is this 
correct? If so, is there a function in OSG that can return an object's position 
inside the PAT in world coordinates, not PAT coordinates? Finally, I would 
assume that what applies to position applies to rotation, is that correct?
 
Thank you all.
 
N. Farr
