How 3D Technology works?

In 1838, Sir Charles Wheatstone first described the process of stereopsis: the process by whichhumans perceive three dimensions from two highly similar, overlaid images. Or, the process by which Avatar looks like a mind-blowingly immersive alien landscape instead of a bunch of brightly colored fuzz.
3D technology has come a long way since Wheatstone developed his stereoscope, then used to view static images and eventually pictures. Now we get to wear Wayfarer knock-offs and enjoy 3D films, television shows and video games.
For some people, seeing cool images might be enough. But others might be curious how Pandora was brought to life, or how TRON: Legacy zapped them into its glowing world. The answer is both reassuringly simple and inordinately complex,depending on who you ask and how you look at it.
How do 3D films work? What’s the difference between polarity and anaglyph (we’ll get there), and what are the next steps for 3D gadgets and imagery? Have a look below for a breakdown of how today’s “it” technology functions. Plus, we put in some sweet looking pictures. What’s not to love?
A tremendous thank you to David Leitner , Rob Willox and Professor Ian Howard for their collective insight and help in describing the various forms of 3D technology below.
