Congratulations on making it to the end of this chapter! Although it took quite a while to re-architect our lighting engine, the results cannot be dismissed as miniscule. The shadows created by this method add a lot of graphical diversity to our world. In the next chapter, we're going to be discussing optimizations that can be applied to make the game run as fast as it possibly can after all of the fancy, clock cycle sucking techniques used throughout this book. See you there!
