by taking two frames of video
one can craft an psuedo 3-D image
as shown here.
These two frames are from a
video for which Q posted a link, from today.
I have made the image so that it
is obvious to tell that there are two video viewers open
at the same time each to a different
frame which are very close in a sequence from
a moving camera.
So we get to see the WTC in 3D. Very cool to see how
massive it really was.
also it might be necessary to flip the images
that I showed, the frames that I used, to put the right on the left,
and the left on the right
depending on weather you view the 3D with
a set of glasses, or if you view it
by crossing and refocusing your eyes., not really like a
Magic eye but close.
