3D fonts

Hi. I am a beginner in openGL and so far managed to output some 2D points and lines on the screen.

Can anyone provide me with a guide to create a 3D font and a 3D circle? Do you use vertex to create the points and then link them?

Any help is appreciated. Thanks.

if you are using windows go to
nehe.gamedev.net
there are tutorials on 3d fonts and a lot of other interesting things there
