\section{Python integration} \label{sec:python} A recent feature of Mitsuba is a simple Python interface to the renderer API. While the interface is still limited at this point, it can already be used for simple automation purposes. To access the API, start your Python interpreter and enter \begin{python} import mitsuba \end{python} For this to work on MacOS X, you will first have to run the ``\emph{Apple Menu}$\to$\emph{Command-line access}'' menu item from within Mitsuba. On Windows and non-packaged Linux builds, you may have to update the extension search path before issuing the \code{import} command: \begin{python} import sys # Update the extension search path # (may vary depending on your setup) sys.path.append('dist/python') import mitsuba \end{python} For an overview of the currently exposed API subset, refer to the following page: \url{http://www.mitsuba-renderer.org/api/group__libpython.html}. \subsection{Fundamentals} All Where applicable, the Python wrapper supports operator overloading, default arguments, and \begin{python} import mitsuba from mitsuba.core import * myVector = normalize(Vector(1.0, 2.0, 3.0)) print(myVector * 2) Log(EInfo, "" +) \end{python}
