Is it possible to use the device's front facing camera with ARCore? I see no references in Google's docs.
I can't find any reference in the docs. It would also make the whole AR process much more complicated. You have to invert the logic for moving the camera etc. And it's much harder to recognize planes as the user is always in the way. Right now, ARCore only recognizes planes so you can't detect feature points, e.g. in the face of a user.
