Interior
The Interior recipe renders a furnished room based on a Blender parent scene created by Nextwave Multimedia.
Above, PBRT rendered the scene with the path tracing integrator.
Above, Mitsuba rendered the scene with the path tracing integrator.
The parent scene contains many objects in a closed space, so it looks brighter and more realistic when rendered with a path tracing integrator, as opposed to a direct lighting integrator. Unfortunately, path tracing integrators can take a long time to finish, and can introduce noise artifacts in the renderings. The renderings above required many minutes for Mitsuba, and over an hour for PBRT.
It would be laborious and error-prone to assign materials and reflectance spectra to all of the objects in this scene, by hand, in a mappings file. Instead this scene uses an automatically-generated mappings file that assigns a matte material and a Color Checker reflectance spectrum to each object. See WriteDefaultMappingsFile().
The executive script MakeInterior.m produced the images above. It is located at here:

InteriorDragon is a variant of the Interior recipe. It includes the dragon model from the Dragon scene, placed on the furniture.
The executive script MakeInteriorDragon.m produces the variant images below.
Above, Mitsuba rendered the scene with the path tracing integrator.
