Displays have seen many improvements over the years but have many shortcomings still. These include rectangular shape, low color gamut, low dynamic range, lack of focus and context in a scene, lack of 3D viewing, etc. We propose Computational Displays, which employ computation to economically alleviate some of the shortcomings of today's displays.
Commodity graphics hardware has become a cost-effective parallel platform for solving many general problems. New Graphics hardware by Nvidia offers an alternate programming model called CUDA which can be used in more flexible ways than GPGPU.
