How to implement HUD

Question

I'm wondering how one could implement an HUD in LWJGL. I've seen tutorials on this, but they don't seem to work. I know the basic structure goes like this:

init3d();
// 3d code
init2d();
// HUD

To which, of course, init3d and init2d are the GL Initialization codes. And also, how would you draw the images for the HUD (or should I ask that in a separate question)?

If this is too vague, let me know and I'll update the question.

Answer 1

The easiest way to handle this is to use a library that's specifically designed for GUIs. Check out Nifty GUI. It works with OpenGL + LWJGL + Slick. Follow the getting started guide and read the tutorials. Finally, check out the source code for the examples. This will get you on your way the quickest, without needing to worry so much about the lower level graphics involved.
