Why I Made This Course

I created this course while learning Metal shaders myself. When I started, shaders felt like magic — online resources either assumed a graphics background or showed cool effects without explaining the underlying logic.

Throughout my learning journey, thebookofshaders.com and Claude became invaluable teachers. Claude, in particular, is very helpful, not by generating long blocks of code, but by helping me understand difficult concepts step by step. I used it as an interactive tutor: asking questions, iterating on small shader snippets, and digging deeper into topics until things made sense. The course is the result of that process — written, structured, and refined by me as I turned that learning into something others can use.

This isn't just a course — it's a documented learning path.

I'm sharing it for free because it helped me reach new creative limits, and I hope it helps you do the same.
