Hi! i'm new here and this is my first message
This is my first steps in Java3d (and in 3d at all) and i have a problem... I want the mouse to be used to look around, like in a shooter. My code is being executed, but nothing happens on th screen. There's something i must have misunderstood.

Otherwise, the keyboard works:
