In this new and improved fourth edition of the highly popular Game Engine Architecture, Jason Gregory draws on his two decades of experience at Midway, Electronic Arts, and Naughty Dog to present both the theory and practice of game engine software development. In this book, the broad range of technologies and techniques used by AAA game studios are each explained in detail, and their roles within a real industrial-strength game engine are illustrated. The fourth edition offers the same comprehensive coverage of game engine architecture provided by previous editions, and this first volume covers essential concepts, techniques, tools, and the engine systems that form the core of every game engine. This book is intended to serve as an introductory text, but it also offers the experienced game programmer a useful perspective on aspects of game development technology with which they may not have deep experience. As always, copious references and citations are provided in this edition, making it an excellent jumping off point for those who wish to dig deeper into any particular aspect of the game development process.
