Hello, I'm trying to find a way to correct the perspective of a projection which shows a room looking through the vantage point of a window. The viewers will be appx. 20' away from the screen and will be moving left to right. I would like to have the image account for the perspective change as they move left to right. Is there a method to capture the location of the viewers through a camera and drive a skew on the x axis based on their position in the room?
