I remember this from a year or two ago. I found it to be a useful entrypoint into a topic that I thought I'd never understand at all. Understanding the basics of shaders has been helpful for some audio-visual tchotchkes that I have enjoyed building. Hope to learn more, over time. And I'd really love to see more of the chapters that are planned, but unavailable. Is there a changelog that will tell us what parts of the book were updated and when they were updated? edit – it's all on GitHub, which is also helpful given how slow the Book of Shaders website is right now: https://github.com/patriciogonzalezvivo/thebookofshaders https://github.com/patriciogonzalezvivo/thebookofshaders
