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.
