2x3D is a simultaneous 2D/3D hybrid theater and its real-time shader for image hiding.
In this project, 2x3D concealment processing is performed using a pixel shader to support the hiding of dynamic motion pictures in real time. In this way, multiplex-hidden images are possible with multiple videos in real-time and stereoscopic 3D can be achieved. 2x3D method does not require any electronic devices such as active shutter glasses for viewers' side, and it reduces the number of required screens and cost of glasses overall.
As an experiment, a stereoscopic 3D left-eye image is shown as the 2D image for viewing with the naked eye while the right-eye image can be seen through a polarized filter.
In this way, audience members can experience a stereoscopic effect by placing a filter over the right eye only. A difference in brightness exists between the two images, but this is not a problem for depth perception as in the anaglyph method.
Not only is this 2D/3D hybrid theater cost-effective for cinemas, it can provide a universal design that accounts for the hazards posed by stereoscopic 3D glasses for children, the stereo blind, and people whose eyes fatigue easily or who already wear glasses.
