1. A computer-implemented method, comprising:
obtaining refraction data;
obtaining mesh data;
generating aligned model data by aligning the refraction data and the mesh data;
calculating refraction points in the aligned model data;
calculating melanin information for the aligned model data based on the refraction points for iris pixels in the aligned model data; and
calculating an approximated iris color based on the refraction points, a melanin absorption coefficient, an iris stroma scattering coefficient, an anisotropy of a scattering phase function, and the aligned model data.
