A method displays an image on a display surface. First, structured patterns are projected on the display surface by multiple projectors Pi. Input images of the structured pattern are acquired. Each input image is acquired by a camera Ci in a fixed physical relationship to a corresponding one of the projectors. The correspondences are triangulated to determine a quadric transfer TPiCk. Quadric transfer parameters are determined of the quadric transfer T. Output images from the projectors are warped according to the quadric transfer and the quadric transfer parameters.
