**** While I completely understand and agree with this discussion, I have
to object to the use of the term cyclopean in connection with the unity
state of stereo perception.
According to myth, Cyclops was a one eyed creature. Therefore his vision was
2D not stereoscopic binocular vision. Not the same thing at all. Completely
diametrically the opposite. *Cyclopean* used rightly refers to the habitual
flattening of perception (an historical human trait), not the enhanced
property of comprehending depth and structure as a unified perception. The
mythical creature embodies one of the dark sides of the human psyche.
Stereoscopic binocular vision transcends the limits of Cyclop's physical
one-eyed constraint, as stereo imagery transcends 2D imagery.
>From the point of view of a stereo interested person, Cyclops is the *bad
guy*, not the hero. He represents by analogy, the forces of those who use
excuses like, *2D is fine for me, why would anyone else bother with
stereo3D?*...
Yes, there is a central unified perception that we gain from our two eyes,
and we can in a limited way represent that with a single 2D image (centered
spatially between two stereo views), but that's decidedly NOT what the brain
perceives in a stereo image. The term cyclopean could only truly refer to a
flattened somewhat artificial 2D version of our true perception. Perhaps
applicable to current network TV? ;-)
