Abstract: A computer system method includes determining a first surface illumination on an object based upon a respective irradiance, determining a first surface reflection based upon the respective irradiance, determining a second surface illumination on the object based upon a respective irradiance, determining a second surface reflection based upon the respective irradiance, receiving a first weighting for the first illumination and the first reflection value, and a second weighting for the second illumination and the second reflection value, wherein the weightings are different, determining a first surface illumination in response to the first illumination value, the first reflection, and the first weighting, determining a second surface illumination in response to the second illumination value, the second reflection, and the second weighting, and determining an image including the object based on the first surface illumination and the second surface illumination.

Abstract: A method for a computer system includes receiving a three-dimensional model of an object, wherein the object includes a surface region, determining an incident irradiance associated with the surface region, determining a plurality of voxels associated with the three-dimensional model of the object, wherein a first plurality of voxels is associated with the surface region, and wherein a second plurality of voxels is associated with a sub-surface region of the object, associating the incident irradiance with the second plurality of voxels, and determining a subsurface scattering contribution associated with the surface region of the object in response to the incident irradiance associated with the second plurality of voxels.
