The code is provided as a single file. There is no build/run instructions, however I could compile by calling `g++ smallmmlt.cpp` (I used gcc 7.5.0), and ran it as `./a.out`. By default, the renderer runs for 3 minutes (see smallmmlt.cpp:525). It generates a ppm images with a cornell box contained 3 spheres (not in the paper, but similar to Figure 8). The 3d scene is defined in code, and thus adapting to other contexts might require some development effort.
Another (unofficial) implementation can be found in EDXRay (https://github.com/behindthepixels/EDXRay/commit/3af2fb67237de651e6ac6877ac07acb38b9fafd5)
