1. A method for estimating a location on an object in a three dimensional scene, the method comprising: producing a plurality of radiation patterns; measuring at least a portion of two or more of the plurality of radiation patterns at one or more detection locations in space; producing one or more illumination vectors, each comprising at least a portion of a plurality of illumination values measured at the one or more detection locations in space; illuminating the location on the object with at least a portion of each of two or more of the plurality of radiation patterns, the illuminated location on the object producing a plurality of object radiations, wherein each object radiation is produced in response to one of the plurality of radiation patterns; detecting the plurality of object radiations; producing a plurality of measured values utilizing the plurality of detected object radiations; and estimating the location on the object based on the plurality of measured values and the one or more illumination vectors.
