3D Technology

The most common 3D Technology used for displaying images on computers these days is through the use of eclipse method, as used in the NVidia 3D Vision. This method involves the use of glasses that alternately blank out the left, then right eye, while the appropriate image is displayed on the screen.

Various 3D Televisions also support this method of display, and are designed to work with NVidia's system.

There are 3 different types of 3D displays being used for Television.
1) The eclipse method, which involves displaying alternating images for each eye, and special glasses that block out each eye alternatively.
2) Polarized light method, which involves displaying light for 1 eye polarized vertically, and light for the other eye polarized horizontally, and uses polarized glasses to seperate the images.
3) Lenticular imaging, which gives different light to each eye, based on different viewing angles, resulting in not needing glasses of any kind, however these normally have a severely limited viewing angle.

The most common 3D technology used to display movies these days is the use of two images projected using polarized light, with associated polarized glasses being worn. This results in horizontally polarized light being seen by one eye, while vertically polarized light is seen by the other eye.
