Yakumo: a Physics-based Game with Physical Input: Implementing a Simple Game Using Ogre 3D Graphics, Havok Physics, and Iphone Accelerometer Control over Wi-fi Daniel Heffernan

Yakumo is an exploration of the different technologies used in making a modern game, including graphics, physics simulation, 3D audio and content creation pipeline design. This book follows the processes involved in implementing a game which integrates all of these components, based on using OGRE 3D for graphics and Havok Physics for real-time physics simulation. This book also tackles common issues with such software, such as creating a camera that does not clip through surfaces, writing multithreaded code, and supporting reliable network communication. Implementation of an I/O library for iPhone OS devices is also described. This allows physical input to the game by taking advantage of the many sensors of the iPhone/iPod touch, including accelerometer and touch-screen input. In 2009 this book won the IBM Open Source Competition award (University of Limerick, Ireland).
