We all know about the various technological improvements in 3D movies throughout the years. No longer do we now need those color glasses to view 3D movies now. But the improvement doesn't stop there. With the introduction of 3D displays on game units and computers that do not require 3D glasses, the technology in 3D image display is trying to go even further.
That's why I thought this is a rather fascinating explanation on the physics of 3D without glasses. Don't miss it if you are curious on how these things work.
