Claim One:
1. A method for configuring a projector system comprising a projector and using a camera, the projector and the camera each comprising an array of pixels, the method comprising: projecting, using the projector, a set of features on a surface assumed to be planar; capturing the set of features using the camera; using the set of features to calculate a homography transform from the projector pixels to the camera pixels; projecting a homogeneous color image using the projector; capturing an image of the projected homogenous color image using the camera; and for each camera pixel of a set of camera pixels, using an inverse of the homography transform to identify a corresponding projector pixel and adding a color value based upon color information of the camera pixel from the captured image of the homogenous color image to a corresponding entry in a light transport matrix that has a row position equal to a row position of the camera pixel and has a column position equal to a row position of the corresponding projector image pixel.
