You are both correct, ASSUMING that the camera is at an angle within the room. If the camera is parallel with the wall you plan on "moving through" and most of the objects in the room, it'll look just fine. I get what your saying though; if you're looking at a cube and you move to the left, you'll start seeing more of the left side. However, if you are completely parallel with it, looking directly at its from face, you will still only see the front.
I'll try and post an example later, probably tomorrow.
