The source code and project for this tutorial is done. You can go ahead and download it. It "should" be self documenting to the point that you don't really need a tutorial, but I intend to write up a tutorial on this page eventually anyway.
However, I would like to get the source code done for the entire tutorial before writing the webpages. That's partially because I hope to have all of the source code so self documented that you don't need any additional explanation and also because I need the code written before I do a web page talking about it. And I want to just get the whole thing out there before spending a lot of time writing the web page.
So, feel free to download the source code and get started. Hopefully, I will get more of a tutorial going on this webpage eventually.
In Part I we look at the basics of creating a terrain grid.
Believe it or not, this is the same grid.
