Abstract:
In recent years there has been considerable interest in modeling
realistic subsurface light scattering in materials such as marble,
human skin, or clouds. Many of these models provide a solution for
the transport equation in a homogeneous or layered scattering media.
The model we present here exploits a diffusion mechanism to provide a
solution to the transport equation. Treating light flux as current we
can use circuit analysis techniques and linear systems to solve
directly for the steady state transport equation and ignore the
transient values. Furthermore we set all non-homogneous light
scattering properties of the medium through real world MRI scans.

Our steady state solution to the light transport equation
as a circuit is quite practical in terms of memory use and
computational complexity and has the flexibility to use real world
models, or user defined parameters such as those an artist might
provide.
