OpenGL 2D Examples - 101 The 2D Basics (w/pics)

I'm rather unsatisfied with how difficult and scattered good OpenGL tutorials are. I'm going to document this stuff here so I can find it and so anyone else interested now or in the future can find it.

This thread is going to focus exclusively on 2D drawing because my immediate interest is exploring the possibility of more lively HUDs to go along with the more lively modding capabilities (whether CSQC or coded in engine doesn't matter to me).

Think vehicle HUDs with speedometers, "Objective Hint Displays", maybe even "mini-maps". We'll see ...

This is going to start very simple and build its way up eventually.

This focuses exclusively on drawing code:

1. No window initialization or texture upload, etc.
2. Assumes a view window of 512 x 512
3. The buffer swapping is assumed to occur at end of every frame

Hi Baker, can we do it to display a Circle Minimap ..can or not?

circle minimap is doable

Quake2xp has it sulgloom also (original code from there anyway).

Was actually gonna try and port it to Q1
