Here I present another one, the Gonzales renderer, written by me. It is heavily inspired by PBRT and written in Swift (with a few lines in C++ to call OpenEXR and Ptex). It is optimized only as far as to be able to render it in a reasonable amount of time on a free Google Cloud instance (8 vCPUS, 64GB RAM). As far as I know this is the only renderer able to render Moana not written in C/C++. I wrote it with vi and command line Swift on Ubuntu Linux and Xcode on macOS so it should be relatively painless to get it compiled on these platforms.
