In your Direct3D 3D engine, how do you draw 2D text? Do you put each letter in a texture?

Usually you will have one texture which contains all the characters. Then you define a grid of quads and manipulate the texture coordinates to represent each character. You draw everything in orthographic mode with alpha blending/testing enabled.

Hello,

Another solution - if you dan't want to write your own writing code - is to create a DIB section and to write your text using the normal GDI functions. This way, you can easily handle multilanguage, kerning and other text issues. Of course, this will be slow as hell.

I believe there is one DX smaple which uses this method, so you might have a look.

Regards,
