Possible is mounting of cylindrical glass (glass for astigmatic eyglasses, from eyglasses shop) in front of projector. The orientation of axis of this glass is crucial! The refraction (in cylindrical diopters)of this glass must by experimentally measured (probing of glasses with diferent refractions, +,- cylinder). I ophthalmologist, my hobby is 3D.

One way to overcome this is to digitally warp the content with a negative distortion. When you project the warped content, The two distortions (screen and warping) add up and cancel each other. |
