Covering OpenGL in a single chapter is impossible. However, this chapter has provided you with all the information required to begin coding OpenGL programs. You know how to render geometry efficiently, how to control the camera, and how to achieve realistic effects using textures and lighting.
Throughout the book, OpenGL code has been used frequently to illustrate some coding principles. That code expands the contents of this chapter, so you can delve into OpenGL's more advanced features such as multipass rendering and vertex/pixel programs.
For those interested in more material dealing with OpenGL, see the official OpenGL web site at www.opengl.org. There you will find hundreds of code samples as well as the full documentation of the API. Particularly useful are the main pages, which can be browsed online and provide an alphabetic reference for all OpenGL calls.
