   I did a lot of this for my raytracer, c-ray [1]. Originally it was just a self-contained C program, but I got tired of writing buggy and limited asset import/export code, so eventually I put together a minimal public C API [2] that I then wrapped with CPython bindings [3] and some additional python code [4] to expose a more 'pythonic' API. It's all still a WIP, but it has already allowed me to write a Blender plugin [5], so now I can play around with my renderer directly in Blender, and test with more complex scenes others have made.

   Fun project, and it's really cool to see my little renderer in the interactive viewport in Blender, but I did learn that I don't particularly enjoy working with non-trivial amounts of Python code.
