Patent ID: 7230620

Claim:
A computer implemented method for rendering a model of an object, comprising the steps of: acquiring, in an acquisition space, a reflectance field of the object, the reflectance field including a set of reflectance images of the object and a model of the object, the model including a plurality of points; deforming, in an object space, the model to generate a deformed model; querying, for each point of the deformed model in the object space, the set of the reflectance images in the acquisition space to obtain reflectance coefficients for each point, in which a query for each point includes a set of operands {Ref(S), (i c , i l ), (x c , y c ), (ω r , ω g , ω b )}, where Ref(S) refers to the point, i c is a camera index, i l is a light source index, (x c , y c ) is an index for a reflectance image, and (ω r , ω g , ω b ) are color weights; shading each point according to the corresponding reflectance coefficients to generate an image of the object corresponding to the deforming; and rendering said generated image of said object.
