Description camdolly moves the camera position and the camera target by the specified amounts.
The units are normalized to the scene. For example, setting dx to 1 moves the camera to the right, which pushes the scene to the left edge of the box formed by the axes position rectangle. A negative value moves the scene in the other direction. Setting dz to 0.5 moves the camera to a position halfway between the camera position and the camera target pixels - interpret dx and dy as pixel offsets. When you do not specify an axes handle, camdolly operates on the current axes.
