How 3D effect work
Our ability to see stereo-vision comes from each of our eyes seeing a slightly different view of the world. The two slightly different pictures picked up by the two eyes is combined into one stereo image by the brain. The parallax is the main factor that creates the stereo effect. The corresponding left and right image points are separated by the distance called the parallax. The two different viewpoints is what creates the parallax.
How 3D displays work
One of the following methods is used by the present display technologies.
-Separate display for each eye (used in HMDs)
-Shutter glasses (most common method)
-Color filter glasses (used in some old 3D movies)
-Polarizing glasses (used in some modern 3D movies)
Polarizing glasses
This technology is used by the projection displays. Here, special glasses are used such that the polarizing directions are 90degrees apart for each eye. So, whatever is projected in one polarising direction is seen by that eye only and those projected in the perpendicular polarising direction is visible to that eye only. Two images are simultaneously projected onto the screen and the brain interprets the two different imagea as 3D.
