FAQ / 17 Using Fonts - Iceweasel
17.010 How can I add fonts to my OpenGL scene? OpenGL doesn't provide direct font support, so the application must use any of OpenGL's other features for font rendering, such as drawing bitmaps or pixmaps, creating texture maps containing an entire character set, drawing character outlines, or creating 3D geometry for each character. Use bitmaps or pixmaps The most straightforward method for rendering simple fonts is to use a glBitmap() or glDrawPixels() call for each character. The result is simple 2D text, which is suitable for labeling GUI controls, annotating 3D parts, etc. glBitmap() is the fastest and simplest of the two, and renders characters in the current color. You can also use glDrawPixels() if required.
OpenGL:Tutorials:Font System - GPWiki - Iceweasel
From GPWiki This page documents a rather simple font system for OpenGL (using C++ ). It consists of two parts - a command-line tool to generate font files from true type fonts, and a component you add to a program to actually load and draw the font. Blob Shepherd uses this font system. While there are certain advantages to using the technique described below, some may wish to support loading of TrueType fonts within their OpenGL programs. James Turk has has put together a class (based on this page) that does just that in GLFT_Font .

*Update* Brandon Mantzey very kindly pointed out a glaring bug in the code accompanying this post… Never fear, I’ve tracked down the idiot responsible (me), and it’s all good now. The bug was actually two bugs – first I was confusing the width in pixels of a character’s texture and the space it takes on screen. Secondly I was working from the bottom left corner of a string, where as I should have been working from the top left.

Texture-mapped font for OpenGL ES - Forum Nokia Wiki - Iceweasel
An efficient approach to implement fonts in OpenGL is to use a single texture-mapped quad for each character. This technique has very good performance and presents nice results. At this link [1] , there is more information on this subject. glFont The glFont tool [2] is a well-known Windows application and API to generate textures for fonts, and to render them using OpenGL.
Chapter Objectives After reading this chapter, you'll be able to do the following: So far, most of the discussion in this guide has concerned the rendering of geometric data - points, lines, and polygons.
Chapter 8 - OpenGL Programming Guide (Addison-Wesley Publishing
Rendering strings without OS support is always pain in the ass. Add different font faces, font sizes and languages into the mix and it is not funny any more. I like typography and I like having good font rendering in my apps. Sean's awesome stb_truetype was such a relief for me. No more big and ugly Freetype to be included with your project! Now that actually generating the glyphs was not a problem anymore, I thought I'd try to create a font cache which would allow me to load few fonts faces and render strings as any font size I please.
