Hi Jonah, I mean that if you were to relate the distance to the color, the zbuffer graph would look something like this:



Instead of just being a straight line. Usually the values in the z-buffer are not actual simple z depths but this kind of proportional value that gives more bits of precision to things that are closer to you.

But the zbuffer would not be antialiased anyway, so that wouldn't really do you any good (except shrinking from a much larger image is a good way to antialias stuff).
