Good value, minor gaps

Recommended, with the caveat that it is not a gentle introduction.

I have been working with physics simulation for a few years now and I still found plenty here that was new to me. A couple of chapters felt like they could have been merged, but that is a minor complaint. There is a section near the end that ties several earlier ideas together in a way I had not seen before. Solid, and I would buy another book from this author without hesitation.

Highly recommended

A superb guide. The examples are small but complete.

This is the third book I have read on physics simulation this year, and it is comfortably the best of them. I particularly liked the way the author builds up from simple cases before introducing the harder material. The code samples assume a particular environment, which took a bit of fiddling to get running properly. The writing is direct and does not waste space on filler, which I value in a technical book. Worth the money and the reading time, without hesitation.
