1.4 The Mathematics of Physics Engines

Creating a physics engine involves a lot of mathematics. If you’re the kind of person

who feels nervous working with math, then you may find some bits hard going. I’ve

tried throughout the book to step through the mathematical background slo wly, but

unfor tunately there’s no way to avoid the mathematics entirely.

If you hav e difficulty following the mathematics, don ’t worry: you can still use

the accompanying source code for the corresponding section. While it is better to

understand all of the engine in case you need to tweak or modify it, you can still

implement and use it quite s
