Recommendation for a beginner's book how to program OpenGL shaders (GLSL)

Dear community, I would like to ask for advice. For using the Structure (from Erogenous Tones) I would like to design my own OpenGL shaders someday.

I know there are YouTube and online tutorials for this. But I am more “old school” and would like to read a book for this. So: can you give a recommendation for a book that can help a complete beginner like me learn how to program aesthetically looking OpenGL shaders (GLSL) for use in Structure?

Thank you and greetings :slight_smile:

Robert

seriously, thebookOfShaders is the way to go. practically speaking, if you pick up any GLSL text book, its going to give you tons of information that you don’t need at all about pipelines, vertex shaders, compute shaders, raytracing, lighting, blah blah blah and all you need to know about shaders for structure or any other video synthesis use case is fragment shader biz rendering to a rectangle.
plus the only way you are going to actually learn how to program is by actually messing around with the code, and the book of shaders has fully interactive real time compiling shader examples built into it so you would need to spend 0 effort setting up a coding environment.
