I have been look at this and it seems the NeHe tutorial for FreeType fonts (http://nehe.gamedev.net/tutorial/freetype_fonts_in_opengl/24001/ ) is the most reasonable solution... There are some frameworks but these seems to be not documented and/or have rumours to be slow. Or maybe there are other solutions you could recommend?
I'm asking for a practical solution, what you personally found the best and most hasslefree.
