Notes:
This is a reupload from a 2013 video
In the source code there are some comments in spanish, sorry for that. :P
Also, the terrain loading isn't well optimized yet, since I use a display list and it may go slow in some computers. I'm on the way to change it to a VBO in order to solve that problem.
