But there's another side to this three-dimensional coin, so to speak, that will make sense to anyone that's ever bought one of those clunky office printer copier things. And I'm talking, of course, about 3D scanning, which is exactly what it sounds like. the process of scanning three-dimensional objects or models into a computer. Now, you can probably guess that it's a little more complicated than your old flatbed scanner, but the general principle of operation is actually fairly similar. The scanner takes many samples of whatever it's looking at and stitches them together to spit out a coherent image, or in this case, a 3D model. Also, somewhat similarly to regular 2D paper scanners, many 3D scanners use light in some way, such as with laser scanners, which can acquire the shape of an object by firing, you guessed it, freaking laser beams, at their targets. But instead of burning and eating them, some laser scanners capture shapes by calculating how long it takes for the laser beam to leave the scanner, hit the object, and reflect back to the scanner. Others use lasers in conjunction with a camera to figure out the laser mark's exact location, which the scanner uses to construct an image. But not all light-based scanners use laser beams. For example, you might have one 3D scanner on top of your TV right now. I'm talking about the Connect for Xbox, which shines infrared light, invisible to the eye, on your body while you're playing Just Dance or whatever. Then it uses a small infrared camera to determine your body's position and whether the club just can't even handle your moves right now.

Well, when combined with a 3D printer, you're basically one step away from your own Star Trek replicator, complete with datab banks full of all your favorite 3D foods. But thanks to the imaginations of people, there's a lot of uses Gene Rodenbury didn't think of. Video game developers are using 3D scanning to capture accurate models to be used in their games instead of designing them from scratch. Doctors and dentists use them to fit orthodontics. And historians are using 3D scanning to preserve and document old artifacts, statues, and even buildings.
