The whole world is 3D, so maybe I should be more specific. This article is to discuss the optical effect of making something appear 3D to a human viewer. This effect can be done a number of ways, but in pretty much all instances this is achieved by having each eye see a different image to create the illusion of depth.

Close one eye at a time and you’ll see that each eye sees something slightly different. This is the real trick to 3D called paralax. The left eye needs to see an image as it would appear from a few inches to the left than the right eye and your brain is smart enough to use this to extrapolate depth. An easy way of showing this to be the real source of the effect is to try closing one eye while using pretty much any kind of 3D technology, and you will see the effect disappear.
