Diffuse_Subsurface_BRDF_Model
Diffuse_Subsurface_BRDF_Model calculates the
scattering from a diffuse material having a smooth exposed
interface. It is similar to Lambertian_BRDF_Model, except that the
coeffients for transmission into and out of the material
are included in the calculation. For SCATMECH version 4.00,
the code was modified to properly account for light which
is reflected back into the
material.
