This book covers the basics in both theory of 3D and implementations using the industry standard OpenGL ES toolkit for small devices. While iOS supports both flavors—version 1.x for the easy way, and version 2.x for those who like to get where the nitty-is-gritty—I mainly cover the former, except in the final chapter which serves as an intro to the latter and the use of programmable shaders. And with the release of iOS 5, Apple has offered the 3D community a whole lotta lovin’ with some significant additions to the graphics libraries. Chapter 1 serves as an intro to OpenGL ES alongside the long and tortuous path of the history of computer graphics. Chapter 2 is the math behind basic 3D rendering, whereas Chapters 3 through 8 lead you gently through the various issues all graphics programmers eventually come across, such as how to cast shadows, render multiple OpenGL screens, add lens flare, and so on. Eventually this works its way into a simple (S-I-M-P-L-E!) solar-system model consisting of the sun, earth, and some stars—a traditional 3D exercise. Chapter 9 looks at best practices and development tools, and Chapter 10 serves as a brief overview of OpenGL ES 2 and the use of shaders. So, have fun, send me some M&Ms;, and while you’re at it feel free to check out my own app in the Appstore: Distant Suns 3 for both the iPhone and the iPad. Yup, that’s the same application that started out on a Commodore Amiga 1000 in 1985 as a 24-line basic program that drew a couple hundred random stars on the screen.
