In this PG http://www.babylonjs-playground.com/#RWIDA by swapping comments around on lines 56 and 57 you can get the camera to rotate about either the x axis or the y axis. When it is rotating about the y axis you see as I would expect the boxes rotating around the camera. When it is rotating around the x axis the rotation is not continuous as it is for the y but swaps orientation at top and bottom of rotation giving an oscillating view. Anybody know how to get a view of the boxes rotating around the camera continuously around the z axis by rotating the camera?
