So it begins..

So I've finally got a start on a GUI system.

First on tap..texture mapped fonts!

I spent the past few days getting a small framework up, texture manager, loading via OpenIL. Some math classes.

Tonight I finally got the fonts working after about two days of headaches trying to get it working, note thats about an hour or two a night if that..

The problem..OpenIL said the image was in BRGA not RGBA. So I swap the image, yay for a OpenIL helper function, and everything worked!

Quickly added colors, ala Quake

Heres a quick image, nothing much but hey its a start since I've been out of the GFX loop for a while :)

I think cypher was referring to the extensions -- which is not openGL, but rather microsoft refusing to keep up.

Looks cool! I originally used Bitmap fonts as well, but it was killing my framerate. Texture mapped fonts had better performance, and made for easy cross platform font management.

Damn nice. I'm currently working on implementing a bitmap font system as well, any tips/source you have?

I used the Bitmap Font builder linked on NeHe, which works really well, Found here. Though I don't like the widths it outputs, so I take the average with and divide it by 2. Which gives that nicely packed look. The NeHe tutorial(s) are pretty good.

I use a vertex arrray to draw each string right now, though I may change it so all text is drawn at once.

Drawing all of that gives over 500FPS right now, in debug its like 10, since I'm using VS 2005 and all the error checking in the STL.
