But the Realist format is five perforations per frame, not
the eight of standard 35mm photography. This frame size
yields 28 stereo pairs on a 36 exposure roll of film.
Well, I never knew the details...all this went on when I was yet
to become a teenager! No idea if any of the slides survived, or
who has them if they did...

No, but a stereo projector, with opposing Polaroid
filters projecting on a silvered lenticular screen
produces a striking effect viewed with the kind of
Polaroid glasses used for 3D movies. My projector
is made by the long-defunct TDC company.
This is one of those things which, to me, sounds like
"It should work, in theory..." but, IIRC, my dad never
sprung for the 3D projector. Was there ever a ViewMaster
equivalent made?

Not on standard monitors, but there are monitors with
a lenticular screen as used on 3D postcards and "tilt
to see moving image" postcards (one vertical, the other
horizontal that can display stereo images without
glasses. There are also other technologies, such as
spinning LED displays, that can dispay what appear to
be solid images in three dimensions.
Every time I've seen "3D" used in reference to computer images,
it has referred to "video games"...and then to more-detailed
images which could provide "fake 3D" through the use of more
accurate shadow images. These images, of course, require larger
files, as well as more effort on the part of the creators...
So, what we need is something which can tell our left eye,
"Okeh, this is what YOU see"...and the same for our right eye.
Next step will be a way to code "touch" data and feed it into
our brains...of course, right after that there will appear a way
to digitize real objects by providing all the data on the type
and exact locations of the atoms involved (as large as it may be,
that is still a finite number...)
