I'd recommend starting there. I think mine may have been Serway's "Principles of Physics" (many years ago). If that is too expensive, look over Dover's publications: they republish older textbooks in inexpensive editions.<br /><br />Unfortunately my university textbook didn't do a very good job of addressing how to do physics simulation. It was aimed at solving individual problems that can be done via calculator.<br /><br />This is where two gentlemen named Baraff and Witkin come in. They ran (still run?) a yearly SIGGRAPH course on physically-based modeling. This is where lots of people I know got started with physics simulation:<br /><br />http://www.cs.cmu.edu/~baraff/sigcourse/<br /><br />There are several physics forums that can help out if you get stuck. Chipmunk's got one; Box2D has one; and Bullet Physics has one as well.<br /><br />It takes a few years of hard work to get an understanding of physics simulation.<br /><br />If anyone else is reading this and has recommendations, feel free to post them below.James McNeillhttps://www.blogger.com/profile/08901649215141005959noreply@blogger.comtag:blogger.com,1999:blog-2403477577476951601.post-31511811187764108842010-02-04T08:35:26.652-08:002010-02-04T08:35:26.652-08:00Hello!

So could you tel me what a book or any other programming guide i can read to understand this library? There are a lot of difficult parameters like p - position, m - mass and so on. Thanks for your time!Dmitry Korzhhttps://www.blogger.com/profile/03506106625420537441noreply@blogger.com
