There are two ways of simulating subsurface scattering within Mitsuba:
|
|
|
|
|
participating media and subsurface scattering models. The latter are described
|
|
|
|
|
in this section and can be thought of as a first-order approximation of the
|
|
|
|
|
former. For this reason, subsurface scattering models should be preferred when
|
|
|
|
|
visually appealing output should be generated quickly and the demands on
|
|
|
|
|
physical realism are secondary.

At the moment, there is only one subsurface scattering model (the
|
|
|
|
|
\pluginref{dipole}), which is described on the next page.
