How does that work?? It doesn't have enough information to show that. If you shift the paint of view, let's say, forward, and you will be able to see things previously covered by a person, but the camera then couldn't see it, so that data was never captured. Even if you have the depth data, it is physically not possible to reconstruct the AR experience.
The only way I can think of is to show blank regions when you zoom around. Show you 3D view when possible, and blank regions when not.
A joke:
Imagine your boyfriend (if you are a girl) takes a photo of you butt naked from your back with LIDAR on, then he "turns on AR experience" after the photo has been taken, then moves the point of view forward to the other side of you, can he see your boobs? If it's AR, he sure should be able to.
