There was a book written by a US college CS professor that I saw a while ago online. I think it was free to read online, maybe other versions were paid. Unfortunately don't remember the professor or book name now. It covered OGL and HTML Canvas. I remember thinking it looked good. Maybe someone else here can say what the book name is. Edit: Maybe covered WebGL too.
