A Bluesky bot that mainly lets you play puzzles based on those from The Witness (but can also do things like solve linear congruences and evaluate expressions). Just tag the bot and speak commands, and it will respond! (Command syntax in the pinned post)The backend logic for the witness puzzles is this repo: https://github.com/WW92030-STORAGE/WITNESS_CLONE_IIThe rest of it is just simple...

Read the readme and find out :3

Docs have largely been uploaded.

Working on some rudimentary docs right now, the README might also be updated directly.

Performance boosts and metrics I do intend to look into, in particular acceleration structures (probably a BVH?) for the ray tracer and more optimized methods (e.g. a better scanline triangle fill and some clipping algos) for the rasterizer.

As for portability, not sure yet, this is meant to more or less be a rendering/animation engine that is lightweight, probably portable to embedded processors like ESP32s?

Yes (software renderer)

Yeah I might make some docs for it soon.
