2x3D: Real time shader for simultaneous 2D/3D hybrid theater It is no longer necessary to screen 2D and 3D movies separately. This project has developed a simultaneous 2D/3D hybrid theater and its real time shader for image hiding. If theaters were able to show 2D and 3D film simultaneously while giving the audience the ability to choose, this would not only benefit cinemas, but audiences who prefer 2D and 3D film as well. 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. 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, the 2x3D method does not require any electronic devices such as active shutter glasses, and reduces the number of required screens and the cost of glasses overall. 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. In stereoscopic 3D, contrast is equally distributed between the left and right images (at 50% each), however, it is also possible to constrict the contrast of the hidden image by passing a mixture ratio to the GPU as a parameter. Using this technique, it is also possible to implement closed captioning or commentary overlay. In the future, greater image quality can be achieved using the wide range color spaces of HDR projectors and optical configuration. 2x3D is a unique solution for improving the current 3D cinema industry for various users of the next generation. http://www.siggraph.org/asia2012/emergin-technologies-detail?id=100-868&session=etech&event=200-742Read less
