A guide to 3D display technology: its principles, methods, and dangers
Guess today is just 3D news day. Here’s a lot of information about the subject if you’re interested.
The simple one first: 3D displays create the illusion of depth by
presenting a different image to each eye. That’s it. And that’s
something that all 3D displays have in common, no matter what. In a fit
of uncommon camaraderie among media and electronics companies, standards
were even developed that encode a 3D stream similarly to normal stream,
except with totally separate left and right eye images baked right in.
There are variations, of course, but it’s a surprisingly practical
approach they agreed on.
