What Is 3D Rendering?Ī graphics processing unit (GPU) is a hardware component that combines data describing geometry, colors, lights, and other information to produce an image on a screen. Reading this chapter is the first step toward squeezing the best possible 3D graphics and visual effects out of mobile hardware. Modern hardware-accelerated 3D graphics underlie all the visual effects produced by advanced mobile products. Without diving into specific programming details, this chapter explains the general approach to producing 3D graphics with OpenGL ES and iOS 5. The 3D graphics concepts explained within this book apply to all 3D-capable embedded systems. Emerging web programming standards such as WebGL from the non-profit Web3D Consortium are poised to enable standardized cross-platform access to the OpenGL ES API from within web pages, too. Special translation layers or “bindings” exist so OpenGL ES may be used from languages such as JavaScript and Python. The C++ and Objective-C programming languages commonly used to program Apple’s products seamlessly interact with ANSI C. OpenGL ES defines an application programming interface (API) for use with the American National Standards Institute (ANSI) C programming language. This book focuses on OpenGL ES version 2.0 for iOS 5 with GLKit. A software framework called GLKit introduced with iOS 5 simplifies many common programming tasks and partially hides the differences between the two supported OpenGL ES versions.

Apple’s devices also support the older OpenGL ES version 1.1. Apple’s iPhone, iPod Touch, and iPad devices running iOS 5 support OpenGL ES version 2.0.

OpenGL for Embedded Systems (OpenGL ES) defines the standard for embedded 3D graphics. Handheld devices from Sony, Nintendo, and others also include powerful built-in 3D graphics capabilities. The vast majority of 3D-capable embedded systems are handheld computers such as Apple’s iPhone, iPod Touch, and iPad or phones based on Google’s Android operating system.
