Have you ever wondered how Minecraft works? It looks like such a simple game, but anyone who has tried to reproduce it, as I have, quickly realizes that this is anything but a simple game. In this video I take a brief look at some of the many technical issues that this game had to overcome in order to become a worldwide hit. I go through various points including: mesh generation, cave generation, biome generation, light calculations and more.

I hope this video informs you a little bit more on why Minecraft is not a simple game, but actually a fully featured engine with many moving components.
