| I started working on a game in OpenGL in MSVC and I want to output text to the screen for debug purposes etc.. But how to draw text on the screen? I have a voodoo2 card, and that's why I can't use DrawText() or TextOut() Windows functions, because those will draw to my ati video card Is there some way to do it whithout writing your text functions? | ||

OpenGL doesn't directly offer support for drawing characters. Rather, it
provides low-level support leaving the rest up to you. If you have a copy of
The Red Book ("OpenGL Programming Guide" by Woo, Neider & Davis), you can
look in Chapter 8 (on page 287 of the second edition) and find source to
font.c which does what you want. Alternatively, you can read that chapter ("Chapter 8: Drawing Pixels, Bitmaps, Fonts, and Images") from the Red Book online right here. While I'm at it, here are some more useful links (these are books online):
