A few weeks ago on "That's Incredible" they had something that really was. This was a full color 3-D effect that requires no special recording, transmission, reception, or viewer equipment. It evidently relies on some psycho-physical processes of visual perception. The developers are from the Univ. of South Carolina, and they are somewhat secretive about the exact technique, pending patents etc. They showed a few samples on the show, and I was quite impressed. I don't see anything standing in the way of some sports broadcasts using the technique within a year or so. Surely some of you net.people know a lot more about this technique.

Was this the technique where alternate frames are for alternate eyes? If so, it has lots of advantages, in addition to those you mention, handicapped people with only one eye can perceive the 3D effect! Apparently the brain compensates somehow for the time-division multiplexing involved. The one real disadvantage is that you only get effectively 15 HZ refresh instead of 30, so there is a greater possibility of flicker.

i think i saw the tail end of the same TI segment, so i may have
misconstrued the technique. if my impression is right, they more
or less rapidly switch back-and-forth between two "stereo" images
and the brain integrates the depth info. kinda like the way one
would move one's head from side to side to get more ocular paralax.
this is especially interesting to me because my eyes don't track
together; i supposedly have about 90% binocular depth perception
impairment. 3-D glasses and stereo slide viewers do nothing for me.
instead, i unconsciously compensate with head movement, visual cues,
and "common sense" (that building that looks 5" tall must just be
far away...).
