Rendering of Binary Alloys - Example and Validation with Bronze

We present the main results of a complete study concerning a small metallic statuette. A collaboration involving metallurgy, optics, computer graphics, archaeology and engineering specialists was needed. The virtual optical aspect computations obtained by spectral simulation is founded on optical measurements of metallic samples wether smooth or rough. The scientific study concerns a small statuette representing a horse originating from China and dated of the "Période des Royaumes combattants" (4th-2nd century BC). The obtained results are relative to reasonable hypotheses on metallurgical knowledge and practice of moulding with bronze. Some pictures both captured from the real object or spectrally computed with the digitized samples are presented.
