Chapter 3 Preview
Chapter 3 is a relatively short chapter on the use of Index Buffer Objects. I'm currently in the process of rewriting pieces of it to smoothen the transition between "Chapter 2: Vertices and Shapes" and Chapter 4, a future chapter on a topic yet to be revealed.
If you haven't read Chapter 2 yet, read it now since you'll need knowledge of Vertex Buffer Objects for upcoming chapters.
Keep on the lookout for this chapter in the near future.
