\subsection{Subsurface scattering models}
|
|
\label{sec:subsurface}
|
|
There are two ways of simulating subsurface scattering within Mitsuba:
|
|
participating media and subsurface scattering models.
|
|
|
|
\begin{description}
|
|
\item[Subsurface scattering models:] Described in this section. These can be thought
|
|
of as a first-order approximation of what happens inside a participating medium.
|
|
They are preferable when visually appealing output should be generated
|
|
\emph{quickly} and the demands on accuracy are secondary.
|
|
At the moment, there is only one subsurface scattering model (the
|
|
\pluginref{dipole}), which is described on the next page.
|
|
\item[Participating media:] Described in \secref{media}. When modeling
|
|
subsurface scattering using a participating medium, Mitsuba performs a \emph{full}
|
|
radiative transport simulation, which correctly accounts for all scattering events.
|
|
This is more accurate but generally significantly slower.
