The goal of this tutorial is to get you quickly up-to-speed with the basics of using OpenGL with GLKit, from the ground up, assuming you have no experience whatsoever. We will build a simple app from scratch that draws a simple cube to the screen and makes it rotate around. In the process, you’ll learn the basics of using each of these new APIs. It should be a good introduction to GLKit, whether you’ve already used OpenGL in the past, or if you’re a complete beginner!
