Texture Fonts

Without getting into any platform specifics, the general approach is: put all the letters on one texture, and store instances of some rectangle class which represent the bounds on the texture of each letter. To render a character, you figure out where it needs to go, set up a quad, look up the rectangle for that character (that would be ((left, top), (left + width, top), (left + width, top + height), (left, top + height)) - possibly in a different order, depending on your API), and apply the corresponding UV coordinates to the vertices of the quad.

It's basically the same as using a spritesheet in a traditional 2D game, except that you need to calculate all four corner positions on the "spritesheet" (your texture) and associate them with positions in the 3D object space (instead of directly with screen positions).

@The OP: This seems to be a cross-post, more or less (even though the content of the posts isn't exactly the same). I don't know if the mods will care in this case, but just FYI, you generally shouldn't post the same question in multiple forums.

Thank you! I'll try that.

I'll have that in mind, I'm sorry.
