In this post, I will compile a list of links or books that I found extremely useful to help me understand how everything works together in OpenGL ES 2.0 and GLKit. I will try to update my post when I find something new, or if I remember other links that I forgot to put in earlier. You can probably imagine that I was inspired by many other blogs or websites all over the internet, but I'm not trying to steal anything, so just e-mail me if I forgot to mention your obscure internet blog.
