[osg-users] About translation

[Franclin Foping]

Hi,
 I am a new OSG programmer and because of the lack of documentation I found it very hard to get everything working. 
 I would like to know the difference between: PositionAttitudeTransform and MatrixTransform
 Secondly, I have tried to move an object in a scene. 
 Basically, I created a node for the object and another for the root so the scene consisted of only 2 nodes. I added a PositionAttitudeTransform as a child node to the root and the object as a child node to PositionAttitudeTransform.  
 When I applied setPosition to the PAT to specify the position of the object  nothing happened!  What is wrong?
 Waiting for your reply,
 Franclin
