Dickinson C. Learning Game Physics with Bullet Physics and OpenGL

Packt Publishing Ltd., 2013 — 112 p. — ISBN: 978-1-78328-187-9
На англ. языке.Modern 3D graphics and game physics can seem like complex and confusing elements of game development from the outside, but this book will reveal what's going on under the hood of two modern and feature-rich graphics and physics APIs: OpenGL and Bullet physics. After you finish this book, you'll be armed with a wealth of knowledge to tackle some of the more advanced aspects of game graphics and physics going forward.
This book can't hope to show all of the concepts and intricacies of modern physics and 3D graphical rendering, but it will cover all of the fundamentals in enough detail to let you hit the ground running when you take on future challenges. And if those challenges involve building an application with the Bullet physics library, then all the better, because you will also learn exactly how this library works from the ground up and help you focus on only the important parts of what you need to know about simulating game physics.Chapter 1: Building a Game Application
