You can adjust all Views of 3D interactive models using the following movements:
Pan: Swipe three fingertips across the screen to pan in any direction. You can also use the arrows of the on-screen 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 View: Tap "Refresh View" on the top left to return to the original Preset view.
Background Color: This button at the top of the screen allows you to toggle between a white or black background for your Views.
