1. A method for virtual, three-dimensional modeling of a subject using a depth-imaging camera operatively coupled to a modeling computer, the method comprising: with the modeling computer, receiving from the depth-imaging camera a brightness image and a coordinate depth image of the subject acquired from each of a plurality of inequivalent vantage points relative to the subject, the brightness image including a brightness value for each of a plurality of pixel positions, the coordinate depth image including a depth value for each of a plurality of pixel positions; in the modeling computer, parsing data from depth images acquired from one or more of the inequivalent vantage points to construct a virtual, three-dimensional model of the subject; determining with the modeling computer, for each of a plurality of loci of the subject, an angle-dependent reflectance based on the brightness and coordinate depth images received from the depth-imaging camera; and with the modeling computer, assigning a surface attribute, based on the angle-dependent reflectance of each of the plurality loci of the subject, to each of a corresponding plurality of loci of the model.
