Two suggestions for the authorSaturday, February 05, 2005
1) Please, for the love of god, use SI units.
2) Code examples in OpenGL for easy portage to Mac OSX / Linux / *BSD. DirectX is not very friendly.
Otherwise, a pretty good intro to various methods of physical simulation. I got a lot out of it.

Archaic units and sparse context saps potentialTuesday, May 04, 2004
While the book has some value (primarily owing to its choice of topic and introductory level), the impact it might have is greatly reduced by its examples reliance on non-metric units -- and a variety of dissimilar choices at that. It makes as much sense as using EBCDIC in your examples in a work on text processing. The result is that the examples suffer a loss of literal value if you wanted to quickly transplant them into a project that has the good sense to use metric measures to avoid confusion over unit conversions.
Secondly, the code examples are sparsely documented. This causes trouble if one wants to transcode one into another language (as I did in taking the flag simulation to Java). One is reduced to blinking and trying to figure out whether the first or second dimension of an array in the author's example corresponds to the flag's height along the pole or its "fly". He's presented a lot in this code, and there are so few comments in it to clarify the arbitrary choices within that a great benefit would have been realized had he added a few. Even had they been taken from the text of the chapter, they would have produced a more valuable result.
I would love to see Mr Bourg attempt a second edition that attended to some of these needless editorial choices.

Well DoneMonday, January 05, 2004
For really, really small objects, Newton's laws of motion don't apply (that's why we have Quantum mechanics and the like.) For everything else, we follow Sir Issac. If you're a game developer, you'll need more than a rudimentary understanding of physics if your aim is realism. David M. Bourg's most recent book covers the theory you'll need to polish your game while keeping it "real."
Inside the covers, you'll discover a review of Newton's laws accompanied by a hearty dose of explanatory graphics. Warning: as a prerequisite, he assumes solid math and basic intro college physics skills. Next, he segues into Kinematics, you know, the underlying mechanics of motion of objects.) He teaches linear and angular displacement, velocity and acceleration. Don't worry, it's not all equations and graphs, he includes helpful sample code (in C) too.
The final chapters cover advanced topics like 3D rigid body simulators and rotations, collision response and particle systems. Before you reach those chapters however, Bourg covers specific examples for projectiles, aircraft, ships, hovercraft and cars.
With the advancement in speed and power of today's microcomputers, achieving reality in games is certainly possible. Bourg's book helps you achieve that without having to spend days in the library pouring over college physics texts. This book is a sound physics review and very well written for the gaming professional.

Nice refresher with basic application in gamesThursday, July 24, 2003
Even if you haven't taken physics, this does give you a nice overview of the science. Everything is covered with the idea that it can be used in games. Naturally there is math involved, but nothing overwhelming. Overall, I found that this can be pretty helpful as a side reference, but it doesn't offer anything ground breaking. Naturally, there isn't much in physics that you can't learn from school...but a lot of people have problems learning physics from school anyway.
