Pan: Swipe three fingertips across the screen to pan in any direction. You can also use the arrows on the virtual joystick to pan up, down, left or right.
Zoom in: Place the tips of your thumb and forefinger on the screen and move them apart to enlarge the structures within the View.
Zoom out: Place the tips of your thumb and forefinger on the screen and move them together, as if you are pinching, to increase the scope of the View.
Center: To center the View on an anatomical structure, tap twice quickly, with one fingertip, on that structure.
Rotate or tilt: Place one fingertip on the screen, then slowly drag your finger in the desired direction to tilt or rotate the model. You can also use the virtual joystick to rotate or tilt the model. To change the axis of rotation, tap twice quickly on any area of the model; that area becomes the new axis of rotation.
Refresh position: This button, in the Actions menu, moves the body back to the size and angle of the originally selected View. If you have changed the appearance of any of the structures (for example, hidden or faded them), those changes remain in place.
Refresh view: Tap the name of the View located at the top left corner or the screen to return it to its initial state. Alternatively, you can tap the "Refresh View" button in the Actions menu.
