Applying holographic effects to prints

Abstract

Lighting information comprising at least the reflectance data of a plurality of regions of an object surface is generated and printed out as a series of relightable holograms. Each of the printed holograms comprises the reflectance data of a corresponding region of the object. A model of the object is generated such that the model also comprises a plurality of portions corresponding to the regions of the object surface. The series of holograms are each affixed to a portion of the model such that a particular hologram of the series which encodes the reflectance data of a particular region of the object is affixed to the corresponding portion of the model. In an embodiment, the model of the object is generated from a metal. The series of holograms is engraved directly onto the metallic model such that a particular hologram of the series which encodes the reflectance data of a particular region of the object is engraved onto the corresponding portion of the metallic model.

         30 . The model of  claim 28 , wherein the lighting information comprised in the at least one holographic print is a bi-directional reflectance distribution function (BRDF) of the respective one of the plurality of regions of the object surface. 
     
     
         31 . The model of  claim 28 , wherein the model is a two-dimensional model of the object.
