Hi Robert,

first of all thank you for your reply.
I am already able to set the correct position by using sethomeposition and then 
calling home, but my problem is that I need to set a specific "up" vector: I 
have tried any possible setting but my camera rest always in the default 
(0,0,1) orientation (I didn't specify that I need to show a point cloud in 
perspective view from the ground).
By using for example TrackBallManipulator instead it works, so it seems that is 
a problem of this manipulator that doesn't allow to set up vector.
Is there a manipulator similar to FirstPersonManipulator that allow to set the 
"up" vector?
Thank you again
