Learning Game Physics with Bullet Physics and OpenGL

Description

A comprehensive set of straight-forward, easy-to-follow tutorials in OpenGL and Bullet Physics that will teach you how modern game physics and 3D graphics work.If you're a beginner or intermediate programmer with a basic understanding of 3D mathematics, and you want a stronger foundation in 3D graphics and physics, then this book is perfect for you! You'll even learn some of the fundamental concepts in 3D mathematics and software design that lies beneath them both, discovering some techniques and tricks in graphics and physics that you can use in any game development project.
