SBS is the simplest possible 3D input format: two views packed into one rectangular frame. It is the universal input for glasses-free 3D displays. The format is small. The stereoscopic pipeline that has to follow it is not.
Every modern glasses-free 3D display uses a lenticular lens. The lens is the shared foundation. What separates the products is the pipeline around the lens: where eye tracking, stereoscopic rendering, and pixel routing run.
