This example is more complex than the previous one. It represents an electronic

# The porous medium
With this last example, we show an original feature: infrared rendering.
-Stardis is able to render a scene in the infrared without the knwoledge of
-the temperature field. The radiative paths that begin at the camera will
-propagate alternately in conductive, convective and radiative path until
-reaching a boundary condition (or a initial condition in a non-stationnary case).
-
-The **run_IR_rendering.sh** script provides an example to launch stardis in rendering
-mode. The scene is an idealized porous medium above a reflective plane. Some parameters
-can be modfied in the "USER PARAMETER" section, such as the resolution of the image
-and the number of samples per pixel. For each pixel of the image, the luminance
-is computed by Monte-Carlo and the number of realizations is the specified number of
-samples per pixel. Computing a high-defition image with little statistical
-noise can therefore take a long time (many hours). The values of the parameters
-that are provided in the script should result in a computationnal time of about a
-dozen minutes on a correct desktop computer.
-
-More information about the rendering is provided in the stardis man page (such as the
-parameters associated with the point of view).
