3d object appears to move apart from target when ARdevice is moved

November 13, 2013 - 4:56am #1

I have a 2D circlular target that has a 3D replica target that appears on it via AR. When I move my device camera to the sides it appears that the 3D target moves away from the 2D target. What is causing this parallax problem? I need the two to appear as one. Thank you.

Is the 3D model centered on the image target plane ? If so, this could explain it, as this is a visual illusion caused by the fact that the target plane is not "hiding" the half of your 3D model which is positioned "behind" the target. 

So, if this is the case, you either need to shift the model along the plane normal, so that it is sitting "on top" of the target, or otherwise add an invisible 3D plane on the target, using a Depth Mask shader.
