1. A method comprising: printing, at a device comprising a processor with a first physical material, a holographic sheet comprising a series of holograms, each hologram of the series comprising at least one holographic pixel that encodes lighting information of a respective one of a plurality of regions of an object surface different from that of others of the plurality of regions; dividing, by the device, the printed holographic sheet into a plurality of separate physical holographic flakes, each holographic flake comprising a respective hologram of the series encoding the lighting information of the respective one of the plurality of regions of the object surface, the number of the divided holographic flakes being equal to the number of the plurality of regions of the object surface; printing, by the device, a physical model of the object with a second physical material, a surface of the physical model comprising a plurality of portions, each portion corresponding to the respective one of the plurality of regions of the object surface; and attaching, by the device, the holographic flakes to the surface of the printed physical model, each holographic flake attached to that portion of the physical model which corresponds to the respective one of the plurality of regions of the object surface.
