So now we have gone over what a vector is and also how to perform simple vector operations, so it's time to get complicated: the Dot product!

In the previous post we learned a little bit about Vectors and what they are (quick quiz: Do vectors have a position? No! That's going to be important again in a minute, so pardon me while I harp on it).

Of vital importance in 3D games, but also very important for a variety of purposes in 2D gaming, Vector math is another one of those branches of Geometry that you may or may not remember from math class (or Physics class). If you're like me, you remember that they look like little arrows and that they're probably important, but if someone was to ask you to help them with something vector related, you would excuse yourself to go to the bathroom and then slide out the window and run away.

Way back in the murky depths of time, this blog contained a few posts regarding math that game developers might find handy. To be sure these posts were largely the only content on the actual blog itself, which made them easy to find for anyone that cared to look.
