Umm, Brent, on this particular matter I think you may be off the beam a
bit. I think they all look like they're at the same distance because
there's only so much distance between my eyeballs. I am of the opinion
that if I could provide myself with a long enough interpupillary distance,
I could indeed tell the diference.
I think there may well be representational/modeling nonlinearities, I
*know* there are perceptual and mediation nonlinearities (for a simple
example, a fixed frequency tone source changes pitch depending on how loud
it is)... I just think this particulat one may be a somewhat bogus
example.
