3D in Games

Wouldnt it be cool if you were able to play games in 3-D. This might seem like a new idea, but this piece of technology has already been around for a while.

We all know about the company called Nvidia ( for those who don't know, it is a major graphics processing unit manufacturer ). This is the company that had released the revolutionary product called the Nvidia 3D vision. There are two modes of 3D vision available to use. One of them is the anaglyphic ( passive ) 3D and the next one is  active 3D. In the anaglyphic 3D mode, there is no need to have any special hardware, just a pair of read-cyan glasses as shown in the picture below is needed.

Since there are two sets of colour filters , they will cancel out the corresponding colours and hence you will see the game in 3D. This technology will be explained in detail later. This mode of 3D gaming is called Nvidia 3D Vision Discover.

The next mode of 3D vision required the use of additional hardware including a special monitor. The below show the 3D vision kit from Nvidia.




This uses the LCD shutter glasses to project 3D. The difference between the previous version and this one is that , the LCD glasses don't use color filters , hence the original color of the image is maintained. More details about the principles of working will be released in the next post.
