Ray-tracing in One Weekend

A Julia implementation of Peter Shirley's Ray Tracing in One Weekend.

Note that this was one of my first projects in Julia, hence not everything follows conventions (especially w.r.t. packaging).

Plus, there's probably a lot of optimizations that can still be done.

Comparison with the C++ version:

• 1200x675 pixels, 10 samples per pixel, max ray depth 50
• Time to render on a Intel Core i5-4460 @ 3.20GHz:
  • C++ (GCC 11.1.0): 59.354s
  • Julia 1.7: 83.867s (@btime, i.e. excluding time for compilation)

Notes

• Fairly straight-forward port from the C++ code, but with some tweaks to make it fit Julia better.
• Not multi-threaded (yet)
