5.0 out of 5 stars Very good indeed!, 22 Jan 2005
This review is from: Real-Time Collision Detection (The Morgan Kaufmann Series in Interactive 3d Technology) (Hardcover)
Many other books have covered similar material, for physics engines, rendering engines and for AI. I have read none that have really done the subject justice, looking in depth at the techniques and providing background information to make sensible decisions. This book changes that: it is a superb, detailed, accurate (as far as I have checked so far) and timely account of one of the most awkward bits of modern game construction.
The biggest strength of this book is its broad range. Ericson steps through the whole gamut of collision detection tasks: from simple collision tests for bullet intersections, through to accurate collision manifold generation for moving objects (the kind of collision data needed for high end physics simulation).
The book includes a wealth of information on geometrical primitive collision detection (working out when a sphere and plane collide, and so on), but so do many other books. He includes information about spatial data structures and how to work with them, covered well in only a handful of other books. He also looks at combining them all together, with really powerful optimisation, and how to write code to automatically generate the collision geometry and high-level data structures from the underlying geometry. I've never seen this covered in more than an off-hand paragraph before, and it makes this book worth double its price tag for serious game developers.
I've worked in the games industry for a long time, and I learned a lot from this book. Already some of his suggestions have made it into the game engine my company owns, and have made a performance difference. I can't think of higher praise than that.
Its not aimed, I don't think, at hobbiest game programmers, because it really handles the subject in great depth (although the simpler algorithms would be useful). It is a serious book for serious developers, and I wouldn't hesitate to recommend it to anyone working at the sharp end of games.

5.0 out of 5 stars Collision detection you say?, 20 Mar 2014
Verified Purchase(What is this?)
This review is from: Real-Time Collision Detection (The Morgan Kaufmann Series in Interactive 3d Technology) (Hardcover)
If you need a quick inside look in a wide variety of collision systems, do not go any further, because this one is it. Written by a gaming veteran, you will be given example of many systems which are given in context of games and animation and the example code definitely helps you understand these systems if you know some programming yourself. I had purchased for my final year of university having studied collision detection and it was a life saver.

5.0 out of 5 stars Good Physics Book, 5 Dec 2013

This review is from: Real-Time Collision Detection (The Morgan Kaufmann Series in Interactive 3d Technology) (Hardcover)
This a good physics book if you want to learn 2D and 3D physics in computer games. Though you need a very strong knowledge of maths before reading this.

5.0 out of 5 stars It's a classic .., 22 Jan 2012
This review is from: Real-Time Collision Detection (The Morgan Kaufmann Series in Interactive 3d Technology) (Hardcover)
Everyone in the field has a copy, so if you're buying your first copy welcome to the club !

Undeniably important and awesome.

I would say, I wish there was perhaps a "fast solutions" companion volume. Sometimes you just want to look up a problem and see ALL of the solution quickly presented with no fuss.

This is not that sort of book: to home in on a problem you'll read, learn, go back a few sections and try to figure out what the summary they are talking about is, and so on.

Nevertheless it's pretty much the standard and really only book in the field, so enjoy!

This review is from: Real-Time Collision Detection (The Morgan Kaufmann Series in Interactive 3d Technology) (Hardcover)
This is a perfect book to understand collision detection and understand how complex the subject can be. The author gives you nice mathematical details and pedagogical descriptions and examples at the same time. This book made me a better game programmer.

This book was very helpful when I was building my own physics engine. There are a lot of code examples, too.
