I personally like these images better than paired viewing simply because they don’t hurt my eyes as badly. I don’t know anything about how these are made, but I suspect there are “stripes” of left/right information, instead of having the entire left image on one side and the right image on the other side. If so, these images allow the eyes to view images in a mostly relaxed state, while paired viewing requires the eye muscles to hold the eyes much farther from relaxed*. Also, you can view much larger images this way than with paired viewing, and change the focus within the window. * Proper paired viewing with lenses mounted to my head is actually better, but just displaying two images side-by-side on screen is hard on my eyes.

I cannot view 3D data with only one eye–I can’t even see a 2D outline or anything. I tried looking with both eyes then maintaining while covering one eye and it still didn’t work. Also, I think some of the problem with seeing the image may be due to focusing abilities; normally, your eye lenses focus to a certain distance while your eye balls simultaneously aim so the views intersect at that distance. Since these images require your lenses to focus at one distance (that of your monitor) while your eyes aim to intersect farther or closer, strongly coordinated eyes will have a harder time seeing the image, while “weaker” coordination can be manipulated easily.

I grabbed the frames, and it’s harder for me to see an individual frame than the motion image, though I can reduce the image resolution further on the frame and still see 3D than I can with the motion image.
