Claim 11:
12. The computer-implemented method as claimed in claim 1, wherein a bidirectional reflectance distribution function (BRDF), which describes the quantity of reflected light of a reflected ray in each possible observation direction as a BRDF value for each point on the surface of the object and for possible angles of incidence of light of an incident ray, is provided for the purpose of creating the data sets, with the result that the reflectance distribution function (BRDF) is a six-dimensional function that contains a four-dimensional angular component with two parameters for the direction of light incidence and two parameters for the observation direction, and a two-dimensional spatial component with two parameters for the corresponding point on the surface of the object.
