or, Cobbling Together Screenshots to Create Stereopairs
If you ever had an “airphoto interpretation” class, and you are at least as old as me, then you likely peered through these suckers in a geography lab somewhere to view pairs of offset imagery in pseudo-3D. And, if you did it enough, you probably got to where you could just relax your eyes and fix your geo-gaze to a distant vanishing point and generate the 3D effect in your brain without the use of the glasses.
So, a test…
With your head a couple of feet or so from the screen (the further back you are the easier it is), can you look “past” these images so that they converge and trigger a forced-perspective 3D scene in your mind? You will try it.
