Pacing and source code examples
All of the systems we're going to be talking about here could have entire volumes dedicated to them. Since time, as well as paper, is limited, we're only going to be briefly reviewing their very basics, which is just enough to feel comfortable with the rest of the information presented here.
Note
Keep in mind that, although we won't be going into too much detail in this particular chapter, the code that accompanies this book is a great resource to look through and experiment with for more detail and familiarity. It's greatly recommended to review it while reading this chapter in order to get a full grasp of it.
