Yep, 3D is a gimmick, most associated (outside of CNN) with those stupid glasses designed to fit Blockheads from Venus. But as you know, there are many different scientific approaches dedicated to tricking you into thinking bullets—or other deadly projectiles such as children—are popping out of the screen and coming right at you. Here's a quick and dirty guide to 3D magic. Most 3D operates on a single basic principle—tricking our dumb, binocular brain into interpreting a 2D image into one with depth. The most basic way to do this is stereoscopy, which is essentially showing a slightly different image to each eye which the brain mashes together into a 3D image. We've broken up the million different ways to do 3D in a few broad categories. Stupid Glasses It's easiest to do stereoscopic images with glasses or other nerdtastic eyewear to change how you see stuff—hence there are a lot of variations in 3D glasses tech. • An anaglyph image is the old school 3D we all know and got headaches from: An image has two different color layers, one for each eye, with slightly different perspectives and when we look at them through those awesome plastic glasses (usually with red and blue lenses) that block one layer in each eye, our dumb brain takes the resulting separate image from each eye and mashes them together to make a 3D scene in our head.
