ABSTRACT:
A computer-implemented method for texturing a modeled surface includes receiving an albedo map corresponding to light scattering under uniform incident diffuse light. The method includes determining, using the albedo map, a local scattering parameter for a multipole bidirectional scattering surface reflectance distribution function (BSSRDF). The method includes texturing a modeled surface using the BSSRDF and the local scattering parameter.
