3D math application book

Recommended Posts

Hi all I'm looking to practice my 3D maths skills. I've read and taken the Game Maths course at Game Institute but wanted some kind of application/ exercise book where I can practice the theory in more concrete game- related examples involving calculating angles, distances, rotations etc. Does anyone have any suggestions on good books please? Regards, Chris.

I don't know of any exercise books that focus specifically on game-related examples. Well, let me take that back. "Introduction to Game Development" from Charles River Media (in which I wrote the physics chapter) has some exercises....maybe 10-ish for each chapter for the math, collision detection, and physics chapters. But I actually don't think these are quite what you're looking for. Some of the other industry textbooks would also have exercises...I'm thinking that "Essential Math" by van Verth et al may have some exercises....I would check but my copy is not here at the office. But I'm not sure. And it too would probably be pretty light in terms of exercise content.

So, my first recommendation would be to make up your own exercise, and to focus it around creating simple games. Doesn't matter what programming language you use to make the game, as long as you have a way to draw things. Doesn't matter how simple the game is, either. You could make a breakout style game, or even pong, and study line/line intersection to do collision detection and simple collision response based on basic geomtry calculations. Put what you've already learned into practice, starting with simple goals.

My secondary recommendation would be to look at the high school and college-level problem-solving books, which are full of exercises...not specifically game related but sharing some of the same fundamental operations and geometric reasoning. Here's a couple of links to the sort of thing I'm talking about. If you have a local college or university, usually you can find this sort of book in the college/university bookstore. I think the usual mega bookstores (Borders, Barnes & Noble in the USA) also tend to carry this sort of thing.

Please note that I cannot endorse any of the books I'm linking to below. I haven't evaluated them. These are linked just based on a quick Amazon.com search.

Geometry for the Classroom: Exercises and Solutions

Sometimes, books like the following are great for learning how to think about geometry:

Another option, if you're comfortable with programming, is to pull down an open source project and see if you can follow the math related code.

Here's a couple of places that might have smaller relevant examples:

http://animadead.sourceforge.net/ (Character animation library)

http://cal3d.sourceforge.net/ (Character animation library)

http://www.codercorner.com/Opcode.htm (Collision detection library)

http://www.gametutorials.com/ (Has a set of intersection test tutorials).

These are all C++ related, but there are probably similar libraries for most programming languages.
