Key benefits

Get a comprehensive coverage of techniques to create high performance collision detection in games

Learn the core mathematics concepts and physics involved in depicting collision detection for your games

Get a hands-on experience of building a rigid body physics engine

Description

Physics is really important for game programmers who want to add realism and functionality to their games. Collision detection in particular is a problem that affects all game developers, regardless of the platform, engine, or toolkit they use. This book will teach you the concepts and formulas behind collision detection. You will also be taught how to build a simple physics engine, where Rigid Body physics is the main focus, and learn about intersection algorithms for primitive shapes. You’ll begin by building a strong foundation in mathematics that will be used throughout the book. We’ll guide you through implementing 2D and 3D primitives and show you how to perform effective collision tests for them. We then pivot to one of the harder areas of game development—collision detection and resolution. Further on, you will learn what a Physics engine is, how to set up a game window, and how to implement rendering. We’ll explore advanced physics topics such as constraint solving. You’ll also find out how to implement a rudimentary physics engine, which you can use to build an Angry Birds type of game or a more advanced game. By the end of the book, you will have implemented all primitive and some advanced collision tests, and you will be able to read on geometry and linear Algebra formulas to take forward to your own games!

What you will learn

Implement fundamental maths so you can develop solid game physics

Know how to check geometric primitives for collisions

Build a Physics engine that can create realistic rigid body behavior

Good book.Now I can build my flight simulator

This is is a great book. They say you can’t judge a book by its cover. I say you can judge it by its source code. I bought two other game physics books and this is the only one I successfully converted to C for Mac while reading through it. I searched Google for game physics source code and found this book’s source code on GitHub. I learned the hard way that if you can’t download the source code and the code in the book is not complete don’t buy it! The only thing I would change is to get rid of the 2D chapters and replace them with terrain and plane collision response recipes later on. Also, there are a ton of typos in the recipe descriptions, but the book’s formulas and code worked fine. And I always had the GiHub source code download to refer back to. Note that in the book it mostly explains how to get the physics working and not the OpenGL graphics. However, the GitHub download should have working OpenGL code. If you are looking for a good game physics book, Game Physics Cookbook is the one to buy.

If you are new to computer physics programming then this is a must have book. It keeps things simple and direct. Explanations are well done and the math is kept simple. I combined this with the "real time collision detection" book and feel like I have a good grounding in the 3d game physics area. Both books tend to focus on basic shapes and their interactions but also give plenty of good info on using those basic shapes to build more sophisticated physical interactions. Where this books falls short is in the 2D area, and this is the reason I took away 1/2 star. In one place the 2D code uses a point slope form of the line to compute an intersection and introduces a divide by zero error directly in the code. The other 1/2 star is taken away due to numerous coding errors and inconsistencies throughout the text. Also the errata for the book is practically nil.But don't let that put you off: the book is an excellent intro to physics programming in general.

Whilst this book provides a useful revision for game industry techniques, this edition cannot be recommended to new starters in the field. This is because this edition is packed with typos and mistakes in both text and code snippets. You must use the GitHub code in conjunction to review and iron out these mistakes: which is a disappointing lack of attention to detail before the book went to press.
