Woah, I just realized that you draw the entire GUI by yourself.

Don't get me wrong, that's pretty awesome in itself, I've done things like that myself. But I'd like to suggest (or perhaps inquire) why you wouldn't just overlay some html?

When I started development, I didn't know that DOM controls could overlap, let alone lay over a WebGL canvas :) I had zero HTML (and general web development) knowledge at the time. Since I have some experience doing this kind of stuff, instead of diving into the scary DOM details, I took the path of least resistance for me (begun implementing a GUI on a nice, clean drawing surface).

Joking aside, it didn't start as a fully-fledged UI. Some scrolling text strings to show a message log first, the ability to move them out of the way later, then implementing a proper window container for them, then introducing the concept of a 'widget', then getting really excited and thinking about a layout system to be able to present multiple widgets per window... that's the way it usually goes :) The GUI turned out a lot more demanding than the terrain engine itself, both in development time as well as rendering load.

In the end, it's all about learning!
