“Cardboard” VR SDK integrated; users with “Cardboard” VR headsets can put the app in cardboard viewing mode, place their phone in the headset and view the 3D models in VR.
Alternatively, AR mode can be enabled, and then instead of using the gyro sensors to move the viewpoint, the AR tracker will be used instead. This has the advantage of allowing the user to move around the object, instead of having their position locked at the center of the object in standard cardboard VR mode.
