AR Render only area around character
I have a character and a large environment tracked to a piece of paper. How could I only render the portion of the environment within the area of the piece of paper? Eventually I'd like to have the character walk, via clicking on a minimap but, keep him centered walking in place on the paper while the environment moves.
For example heres a crappy drawing. Essentially just a top down camera centered on the character but, since I am AR and the mobile device is the camera I'm not sure how to do this. 
"large environment tracked to a piece of paper." Can you clarify this? Do you mean you have a static image of the whole map, and want to show just the section where the character is?
Yes exactly but, have the character move and the view move with him. Super simple like top down viewport centered on the character. I am just unsure how to do this in AR since the camera is controlled by holding the mobile device.
