I can't free-view (parallel vision) just anything! Fortunately, I can
cross-view very easily, I think my eyes go naturally that way ;-)
In effect, when I first saw SIRDS (Random Dot Stereograms), and I didn't
know anything about parallel or cross-eyed viewing, I started to cross-view
them, and I wondered how other people could see a flying horse or a dragon
or stuff like that. Since then, I've never succeeded to free view (well, a
few times I could see something, but blurred and for a short time); but I
found on the web a source for viewers for SIRDS (I can't remember the
address, anyway it's on the 3D Webring).
The same applies to stereo pairs: I can easily cross-view them and I can't
free-view them. I found a viewer for them, too: it's a reflecting
stereoscope from a German factory, which I saw on a Sigma-Aldrich catalogue,
a big company who sell chemicals and lab supplies (chemists use
computer-generated stereo pairs for 3D perception of molecules); it's quite
overpriced (about 70$ shipping excluded), but it works really good, from
little images (even less the size of a standard print, e.g. prints from my
Realist) to poster-size pairs (except it gives a little doubling of the
image, I thing because you're seeing it through 2 consecutive mirrors).
And I have to thank my girlfriend who gave it to me for Christmas a couple
of years ago!
