    Drawing text on a cube

    Hello,
    I want to display text on each of the 6 quads of a 3D cube.
    I haven't got a clue how to even start...
    My browser tells me that NeHe's tutorial "can't be displayed" and I'm really lost here.
    Sorry for the newbie question, but if anyone can please help, it would be great!

    Re: Drawing text on a cube

    You should try nehe.gamedev.net again, I was just there without any problems.

    here is the code example lesson06 from nehe, loads a BMP bitmap to a cube:

    I want to display text on each of the 6 quads of a 3D cube.
    I haven't got a clue how to even start...
    My browser tells me that NeHe's tutorial "can't be displayed" and I'm really lost here.
    Sorry for the newbie question, but if anyone can please help, it would be great!
