  • How Awesome Would This Be?

    Posted by Shannon Love on August 22nd, 2011 (All posts by )

    Kids still say “Awesome”, right?

    Anyway, this is actually technically feasible although I don’t’ think it would be quite as easy as he thinks.

    Depth Perception

    You know, I really should have titled the post, “How Awesome Will This Be?”

    Well, it will be awesome for most of you out in Internet land but since an obstetrician, whom my grandfather unflatteringly called, “an old horse doctor,” poked my right eye out at birth, I will never experience parallax based 3D because it requires two eyes for stereoscopic vision.

    But don’t let that stop your enjoyment. I’ll just set over here and sulk while waiting for holograms.

      This is so like something my Dad would have done, when we were kids, to prove some scientific principle or other.
      Damn, I still miss him.

      If I close one eye, I can still appreciate these 3D photos.

      I’ve amblyopia in one eye. It’s line of view is so far out of alignment with my ‘good’ eye that I essentially turn it off in the brain. If I close my good eye, the bad eye works fine (actually, with sharper color acuity), but lack of exercise makes focusing difficult.

      As a result, I’m monocular, too. I’ve been waiting for someone to come up with a pair of glasses that projects onto a screen contained within an eyeglass frame, adjustable to the right angle.

      I do miss 3D vision and would cope with the geekiness of wearting such a thing.

      When everyone routinely walks around with HUD glasses, this will be a commonly available app.

      Constant,

      There are several techniques for creating pseudo-3D images. One of the oldest is to superimpose two or more focal lengths on the same image such that the background looks as crisp and clear as the foreground. That causes the brain to generate an illusion of depth although the depth is always misjudged.

      The images you link two have two rapid ally alternating perspectives and multiple focal lengths which create and brief illusion of depth.

      Same problem – no stereoptical depth perception.

      Ruining a promising NBA career – you go nowhere just playing defence. Wrestling became my sport of choice – plus it gave a young man valuable dating skills!

    7. Michael Kennedy Says:

      A surgical resident in training with me was found to have amblyopia and no depth perception. Since this was general surgery, depth perception was pretty important, the professors helped him get a plastic surgery residency and he was henceforth working in two dimensions. Some of us had doubts. That was 40 some years ago. He plays pretty good golf, better than his surgery. I’ve wondered a bit about that.

    8. Doug Jones Says:

      I had exotropia as a child, corrected surgically when I was 13. (This happens to be a family genetic trait- I, my son, my grandfather, and his great uncle, Guiseppe Garibaldi, all had a wandering eye. My son had surgery at age 10.) Even without stereo vision, I could visualize 3D objects by moving my head sideways, using time-integrated parallax to infer the third dimension. Look on the bright side, not having stereo fusion probably enhanced your ability to visualize 3D objects, and raised your score on IQ tests :)
