This is my attempt at Peter Shirley's Ray Tracer in a Weekend book.
The code is a unity build in Handmade Hero style (no virtual functions, all data in POD types, discriminated unions instead of subclasses), and is not organised perfectly but hey, I don't write C++ for a living so don't judge me.
There is a single build.sh script which runs the compiler, a run.sh script which will run the exectuable and produce a test.ppm image.
There is also a preview.sh which will open the OS X preview window on the output image.
I found it useful to run all three together like this:
./build.sh && ./run.sh && ./preview.sh
This is the output of the random spheres example at the end of the book.
