Part 2: Casting Rays
--------------------
*Hey!* Check out the video screencast of part 2: http://screencast.com/t/NNLVxjHZH5
Last time we covered Big Blue's childhood, springing from Seth's mind into Outlaw Editor and then being converted to bits in a file. Now we'll take a detour to introduce ray casting, a critical influence in Blue's life.
You see, before Big Blue can make his debut on the Apple II screen, we need to know where on that screen he should appear. We know he's part of a window on a certain building in the town, but he should only show on the screen when the player is looking at that building. To figure that out I'm afraid we're going to need math but I promise I'll keep it light.
