Interaction mode	Sets the mouse-3D-window interaction mode: Trackball (Default): Motion occurs when mouse button is pressed and the mouse pointer moves. Joystick: Motion occurs continuously as long as mouse button is pressed. Flight: Left mouse button press produces forward motion. Right mouse button press produces reverse motion. Moving mouse during motion steers user in desired direction.
Plane interpolation	Switch on/off smoothing (nearest neighbor) of the image planes.

Volume of Interest | Hide box	Hide the Volume of Interest (VOI) box in the 3D window
Hide control panel	Hide the control panel on the right-hand side (e.g. for enabling full-screen 3D window)
Orientation box	Toggle on/off the display of a image volume orientation box in the bottom right corner of the 3D window. The letters on the box indicates the following; A: Anterior, P: Posterior, R: Right, L: Left, I: Inferior, S: Superior.
