1. A method for reducing view-dependent artifacts in a multi-projector system, the method being carried out by a computer device having a processor and system memory, comprising the steps of: measuring, from multiple viewpoints, and inputting into the computer, data relating to projection characteristics of each of a plurality of projectors of the multi-projector system, the plurality of projectors producing a composite image of an image frame; the computer remapping, for each projector, the projection characteristics from the multiple viewpoints to a common coordinate system; the computer estimating view-dependent projection parameters for each projector based on the remapped projection characteristics; and the computer computing rendering parameters for each projector based on the estimated view-dependent projection parameters so as to reduce view-dependent artifacts.
