I learned so much from this website many years ago when I was first discovering webgl programming. It is unfortunately unfinished, yes, but those unfinished chapters on advanced topics make for curiosity and the desire to learn more. There are plenty of other resources that fill in the details, but this is a great beginner guide.

interesting that even though it’s such a cherished resource no one’s taken up the flag to complete it after all this time.

Try looking up Ben Cloward on YouTube. He's quite concise and thorough.

Yes, this is exactly what this website is for, and the interactive examples put you right in to programming in glsl and give such an awesome base to experiment.

There are plenty of resources out there as you get more advanced, but imo bookofshaders is a great starting resource.

Honestly this is exactly the kind of area where I’ve found things like OpenAI’s Deep Research and Anthropic’s Advanced Research help a ton. Tell the LLM what you’ve learned, what kinds of things you want to know, and if you don’t know what you want to know then heck, tell it how you feel (like you just did in this comment). I generally try to give it a nice chunky paragraph or two of background and questions.

In my experience, the LLM is usually good at surveying the field, finding resources you might not have found, and evaluating the quality of learning resources. The report that comes back might be super juicy, or it might just point you in some new directions, but it will probably help you get unstuck.
