Abstract
A source image to be projected onto a projection surface is transformed based on a three-dimensional representation of the projection surface to create a modified source image. When the modified source image is projected onto the projection surface, a resulting display image is less distorted as compared to the original source image than a resulting display image would be if the original source image were projected onto the projection surface.
