Brief History of 3D glasses
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.
The first generation modified the games themselves to make them compatible with stereoscopic 3-D. The games' creators had to specifically support each type of LCD glasses -- hardly an ideal situation. There was no guarantee that the glasses you'd bought would work with your favorite game. As you can imagine, that didn't appeal to many people; so a second solution was developed.
This second solution was to override the game, actually taking over the computer's screen and altering what was displayed. As far as the game was concerned, it was just doing what it normally did, except, of course, that some of the computer's time was taken up processing the image to make it 3-D. The result was slower performance and low-resolution, blocky images. It did work with hundreds of games, though, and that was a definite improvement.
The third generation worked in a similar way, modifying the graphics driver but also maintaining the resolution of the images -- no more blocky graphics! Unfortunately, it wasn't compatible with many games, though it was a definite forerunner to the 3-D glasses we have nowadays.
In the fourth-generation models, compatibility is high, the complicated work is done by the graphics card, and the lightweight LCD glasses flick so rapidly between the two images that all we see is crystal-clear, 3-D images.
Overview
3D PC glasses are designed for the serious gamer in mind. What are these specialized glasses, you ask? They are glasses that make the video games come to life in a way that increases the overall gaming experience for gamers of any age. You can do many things with these incredible glasses.

About
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.
Most computer users are familiar with 3-D games. Back in the '90s, computer enthusiasts were stunned by the game Castle Wolfenstein 3D, which took place in a maze-like castle. It may have been constructed from blocky tiles, but the castle existed in three dimensions -- you could move forward and backward, or hold down the appropriate key and see your viewpoint spin through 360 degrees. Back then, it was revolutionary and quite amazing. Nowadays, gamers enjoy ever more complicated graphics -- smooth, three-dimensional environments complete with realistic lighting and complex simulations of real-life physics grace our screens. But that's the problem -- the screen. The game itself may be in three dimensions, and the player may be able to look wherever he wants with complete freedom, but at the end of the day the picture is displayed on a computer monitor...and that's a flat surface.
3D Gaming Glasses Technology
It's official: 3-D glasses are back in vogue. You cannot go to the movies, or watch TV today without hearing about 3D everything. Movies like UP and Avatar are giving 3D technology a major comeback. I think every child remembers putting on a pair of cardboard 3D glasses in hopes that is was going to make viewing the world incredible. Those kids were always disappointed. With the improvements to movie and gaming technology, it was only a matter of time before people were going to try to make games into 3D. A new product on the market is trying to accomplish that by creating 3D glasses for the PC in hopes of making gaming really come to life. This moves the technology well beyond the James Cameron movies, as there is a huge buzz all around edimensional 3D gaming glasses for the PC, which are expected to bring the entire technology of 3D PC Gaming Glasses to a whole new level.
Whar Are 3D PC GLASSES
All gamers want the most realistic gaming experience possible. 3D PC Glasses claim to make that possible. Different companies have been making different types of 3D PC Glasses, but most of them claim to work on most types of PC's. They should work on virtually all PC Games, turning them into a fantastic 3D experience. They should also be able to work with both CRT and LCD monitors.
Often you will have two different types of glasses, wireless and wired. The wireless glasses are going to be a little bit more expensive, just like wireless controllers for video game counsels. The wireless glasses do need to be plugged into your computer but you should not have many problems with that. Both pairs of glasses should be adjustable and easy to use.
Glasses should come with the necessary software needed, as well as an instruction manual. Setup should be a breeze. Glasses probably will not work on a laptop monitor however. You can check out this article on how to make 3D PC Gaming Glasses, although ones you make won't be as effective as ones made by professional companies.
Stereoscopy
Stereoscopy (also called stereoscopic or 3-D imaging) refers to a technique for creating or enhancing the illusion of depth in an image by presenting two offset images separately to the left and right eye of the viewer. Both of these 2-D offset images are then combined in the brain to give the perception of 3-D depth. Three strategies have been used to accomplish this: have the viewer wear eyeglasses to combine separate images from two offset sources, have the viewer wear eyeglasses to filter offset images from a single source separated to each eye, or have the lightsource split the images directionally into the viewer's eyes (no glasses required).
Side-by-side (non-shared viewing scenarios)
Traditional stereoscopic photography consists of creating a 3-D illusion starting from a pair of 2-D images. The easiest way to enhance depth perception in the brain is to provide the eyes of the viewer with two different images, representing two perspectives of the same object, with a minor deviation exactly equal to the perspectives that both eyes naturally receive in binocular vision.
If eyestrain and distortion are to be avoided, each of the two 2-D images preferably should be presented to each eye of the viewer so that any object at infinite distance seen by the viewer should be perceived by that eye while it is oriented straight ahead, the viewer's eyes being neither crossed nor diverging. When the picture contains no object at infinite distance, such as a horizon or a cloud, the pictures should be spaced correspondingly closer together.
Characteristics
Little or no additional image processing is required. Under some circumstances, such as when a pair of images is presented for crossed or diverged eye viewing, no device or additional optical equipment is needed.
The principal advantages of side-by-side viewers is that there is no diminution of brightness so images may be presented at very high resolution and in full spectrum color. The ghosting associated with polarized projection or when color filtering is used is totally eliminated. The images are discretely presented to the eyes and visual center of the brain, with no co-mingling of the views. The recent advent of flat screens and "software stereoscopes" has made larger 3D digital images practical in this side by side mode, which hitherto had been used mainly with paired photos in print form.
