View cameras are very costly.  I'll bet stereo view cameras are too. ;-)
The geometry of the projection is pretty straight forward, are image
manipulating softwares able to distort scans based on a specific
geometry?
I'm a yokel and I got no fancy compooters and stuff. :-(

Yes there are lots of those pop-up anaglyph pictures in text books for
drafting and math and chemistry stuff.  These are the line drawings
that I've seen and computed for my own geometric drawings.  But I
never saw the photographic kind before this week.

(Well, enjoyment is useful, it's true!)
Or a free standing portrait of your house, or spouse, or car, or dog,
sitting on your coffee table.  How about projection, animation,
polarization with full color?  One characteristic of these
"phantograms" is you can place actual objects beside them and it
enhances the illusion.  Or you can measure them in actual space with a
ruler.  Or who knows what else?

Oops, I'm raving again all over the place, aren't I?  Got too worked up.
Sorry to get my anamorphosis on your stereopsis.  It wipes right off.
