title: how does normalizing vectors go with game programming
body: <p>I was unfortunate enough to attend a high school that did not care about preparing students for college, but I'm studying some game programming, and everything programming I get, but I'm taking a Game AI course and we're learning about FSM's and AI movements, and I came across "normalize", looked into it and it kind of makes sense, but how would I use this in game programming? Maybe I just don't understand the concept that well (never really took an algebra class, although I use way higher level mathematics everyday in other programming, however I learn as I go), but I just don't get why I would need to do that. </p>
