Fonts in OpenGL
Author
I was wondering about something:
In SDL, to write something in the screen, you have to use an image which contains the fonts. or you can write your own function that will draw the letters, depending on your own drawing skills. My qustion is, what happens in OpenGl? Do u still need to have the picture with the letters in your computer to write text?
thanks
NeHe has a tutorial on doing bitmap fonts in OpenGL. Yes you do store the image in memory to write text, but as an OpenGL texture.
With wglLoadFont or whatever the function is, Fonts in OpenGL are pretty *** easy. check out nehe.gamedev.net tutorials on the font subject.
Getting nice wrapping fonts is trickier... I''m currently looking into the FreeType2 docs to do this.

Be careful though. Those wgl functions are Windows specific. So if you want cross-platform, you can''t use them.

...remember just that using wglLoadFont produces good looking fonts but it''s *REALLY* slow... A 2d blitting of portions from a textured font is by far faster in OpenGL.

I''ve read a couple of your other threads and, while I don''t mean to sound like I''m flaming you, you really should do at least MINIMAL ressearch before posting threads. Many of them can easily be answered by looking through the docs real quick (for SDL) or by reading the NeHe tutorials.
If you''ve never heard of NeHe, I suggest going there and doing the tutorials. While NeHe isn''t going to teach you how to get the most out of OpenGL, it''ll teach you enough to get some rather good stuff going. You should have a look at the tutorials there before posting a thread, and only post if the resources there don''t answer your question.
It''s just a little irritating having to post the same link all the time.
Try here for tutorials on bitmapped fonts, as well as other means of displaying text in OpenGL. NeHe tutorials.
