How do we see depth? The common meme is to say binocular vision is the cause of it, but cover one eye and the world doesn't suddenly become a flat painting, so I'm sure there's more to it. I imagine color(via the lighting) is involved as well, for one.

So how come brain/eyes are able to accurately judge depth/distance.

inb4 point perspective, i mean the actual biological way it happens, not how we can model it in art.
