Stereo 3D Viewing Techniques
In principle, all stereo 3D techniques share a common approach: both artificially created views for the right and left eyes must direct the eyes through what's known as image separation.
If the quality of the artificial views is good, the brain reconstructs a three-dimensional image. The differences in the various techniques lie mainly in how image separation is achieved in practice.
