Stereoscopic 3D rendering

3D television and 3D glasses are becoming much more prevalent with the latest trends in consumer electronics and technological advances in wearable computing. In the market, there are currently many hardware options that allow us to visualize information with stereoscopic 3D technology. One common format is side-by-side 3D, which is supported by many 3D glasses as each eye sees an image of the same scene from a different perspective. In OpenGL, creating side-by-side 3D rendering requires asymmetric adjustment as well as viewport adjustment (that is, the area to be rendered) – asymmetric frustum parallel projection or equivalently to lens-shift in photography. This technique introduces no vertical parallax and widely adopted ...
