The 3D games we play and love are all made up of thousands, if not millions, of colored straight lines and other edges. And because of the way that these appear on your screen, they can often look jagged and distracting. In the fifth part of our deep look at 3D game rendering, we'll explain what methods are used to smooth out the edges of the worlds we play in. Not as much math this time, though, so that's a bit of good news!

Since we're just going to dive right in to see how this all works, you might want to check out our 3D Game Rendering 101, if you're new to the whole shebang. After that, you can catch up with the more complex elements of rendering in the articles below.
