1. A method of generating composite images with a projection system comprising a first projector and at least a second projector, comprising: generating a correspondence map of pixels for images by determining offsets between pixels from at least a second image from the second projector and corresponding pixels from a first image from the first projector; receiving a source image; warping the source image based at least in part on the correspondence map to produce a warped image; and displaying the source image by the first projector and displaying the warped image by the second projector to create a composite image, the warped image comprising image pixels that are offset by a fraction of a pixel with respect to corresponding image pixels of the source image.
