hi, it seems that vuforia cannot track images at a nearly perpendicular angle. Say my target is lying on the table, it can't be detected while i'm holding the device upright.
Another thing is we want to be able to make "permanent" objects in the scene seem to be moving with the device. By permanent, we mean it's always there and a child of the ARCamera. but we want their rotations to be consistent with what the camera sees. What's the best way to do this?
