Ray (path) tracer based on the book Ray Tracing in One Weekend by P. Shirlley, T.D. Black and S. Hollasch.

There is a commit for every chapter of the book (plus some extra for special subsections) where the results of the chapter can be seen. The code can be built and executed with dune exec raytracing inside the bin folder (due to the path for the result images being harcoded).

Possible improvements:

• Non-harcoded result paths.
• Parallelization of the calculation (final image takes 8h. to be rendered on a 2018 Macbook Air).
