We need more articles as polished as this one. WebGL is a topic I wanted to get into for a while now but it's really difficult to find good content about it. Please keep sharing more experiments!
Could not agree more. Heard good things about https://webgl2fundamentals.org/, but I think it directly jumps into code without any background as such. At least that is what I felt. Not sure whether this is the only way to go about teaching WebGL.
