updated. In fact the problem is the display() function is not not called continuously so the rendered scene doesn't  reflect the new camera position

You need to have something calling display several times. You need to use an animator.

"To perform animation, we need an animator to drive the drawable's display() method in a loop to refresh the display regularly."
