imagine im using a projector and im too close to the projector surface to bring things into focus, can i create a shader program that will modify its input so that things are in focus on the screen?
rason for this is i created a multi touch dj platform, i carefully selected an expensive projector with the correct throw ratio, but the minimum distance was a bit of a lie. i can see things fine on the screen apart from the text in the middle, i cant quite read anything below 10pt unless its on the side. i would like for the dj software i made to have a shader that will adjust the focus.
please tell me thats possible, ive no doubt in my mind that it is, just cant think how.
