Top left: 3D mesh obtained using 3D scanning (close-up of nostril). Bottom row, from left to right: normal map used to give rendered surface subtle detail, and albedo map used to approximate the presence of external materials (such as hair) on top of the skin. Right: final result rendered using the BioSpec model (EG'2004) and a spectral path tracer.
