Column Interleaved Stereo

Column-interleaved stereo works by interleaving the left and right eye views on every other vertical column in the display. The stereo hardware either separates them into two separate displays or blanks the even or odd columns in sync with shutter glasses, or otherwise makes them visible only to one or the other eye, in the case of autostereoscopic displays. The only special requirements for the graphics accelerator are that it provide a stencil buffer which is used to generate the alternating columns in the final image. This mode is generally supported by low-cost gaming GPUs.
