-How 3-D PC Glasses Work

Only a few years ago, seeing in 3-D meant peering through a pair of red-and-blue glasses, or trying not to go cross-eyed in front of a page of fuzzy dots. It was great at the time, but 3-D technology has moved on. Scientists know more about how our vision works than ever before, and our computers are more powerful than ever before -- most of us have sophisticated components in our computer that are dedicated to producing realistic graphics. Put those two things together, and you'll see how 3-D graphics have really begun to take off.

A Brief History Of 3-D Glasses

So, we've seen that although there might be something complex going on behind the scenes, with the right equipment we can just sit back and let our eyes do the work. Of course, the technology wasn't always so simple; there have, in fact, been four generations leading up to today's 3-D glasses.

A Different Point Of View

The key to stereoscopic vision is depth, and our brain will happily take care of that for us, providing our eyes are given the right information in the first place. This is exactly how those red-and-blue glasses work -- each color filters out part of the image, giving each eye a slightly different view. The brain puts the two different images together, and those blue-and-red blurry images turned into a fantastic 3-D comic, or movie, or TV show.

Buying

Although the basic technology is the same, there is a range of different glasses out there. You'll find lightweight, wireless glasses, as well as more basic (and therefore cheaper) pairs. The view through the glasses depends more on your computer's graphics card than the make of glasses, but you will find that different manufacturers offer extra software or other minor incentives. The lesson is: Shop around! If you get the chance to try a pair out before buying, don't hesitate -- try to imagine wearing them for an hour of intensive gaming. You might want to put in the extra money for a slightly better model.

Getting Synched

It's all down to the power of liquid crystal displays, or LCD. Just like the liquid crystal in a watch can be changed from transparent to black, the lenses of PC 3-D glasses can be transparent or opaque. In other words, the glasses can control which eye sees the image on the screen, and with careful timing you've got perfect 3-D. Here's how it happens:

Seeing in Three Dimensions

Human beings, like most other creatures, are equipped with two eyes, situated close together and side by side. This positioning means that each eye has a view of the same area from a slightly different angle. You can check this out by focusing on a distant object and viewing through each eye alternately -- see how some things seem to change position slightly?
