Klappentext What does it take to build an iPhone app with stunning 3D graphics? This book will show you how to apply OpenGL graphics programming techniques to any device running the iPhone OS -- including the iPad and iPod Touch -- with no iPhone development or 3D graphics experience required. iPhone 3D Programming provides clear step-by-step instructions, as well as lots of practical advice, for using the iPhone SDK and OpenGL. You'll build several graphics programs -- progressing from simple to more complex examples -- that focus on lighting, textures, blending, augmented reality, optimization for performance and speed, and much more. All you need to get started is a solid understanding of C++ and a great idea for an app. * Learn fundamental graphics concepts, including transformation matrices, quaternions, and more * Get set up for iPhone development with the Xcode environment * Become familiar with versions 1.1 and 2.0 of the OpenGL ES API, and learn to use vertex buffer objects, lighting, texturing, and shaders * Use the iPhone's touch screen, compass, and accelerometer to build interactivity into graphics applications * Build iPhone graphics applications such as a 3D wireframe viewer, a simple augmented reality application, a spring system simulation, and more Zusammenfassung Offers a crash course on the OpenGL graphics library! with an overview of iPhone 3D development. This title helps you work step by step with OpenGL ES! a graphics library designed for embedded systems such as mobile phones! by progressing from simple to more complex programs.
