    OpenGL question.

    How can I use variables in this function?

    glVertex3f(-1.0f, 1.0f, 0.0f);

    Would it be something like:
    Code:
    float red = -1.0;
    float blue = 1.0;
    float green = 0.0;
    
    glVertex3f(red, blue, green);
    Its just the 'f' on the end of the number that's confusing me.

    Post Yes!

    Yes, you can do that. BTW, The `f' is a hex number I think.

    no its not. The f is a float, you can do exactly as you've shown above.

    Try nehe.gamedev.net for some great openGL tutorials. www.gametutorials.com is also very good.
