For the use case you have specified here yes you need to specify the values of xOffset and yOffset for each angle of view separately.

I am trying to recognize a 3 model from different angles. For that I took images of that model from different angles.
What I want is that my overlays should be at the same position no matter of the angle of view. So, do I need to specify xOffset and yOffset seperately for each angle of view or is there any other way of doing so, because this way would take a lot of time which is not appropriate.
