    URGENT !!! Text in OpenGL window (Nehe)

    Howdy hooo!!!

    I use the glPrint function which is on the Nehe site:
    http://nehe.gamedev.net/tutorials/lesson14.asp

    Why doesn´t the text size change ???

    Another question:
    I should print some text in a OpenGL window and when I used windows API the text flickered like hell.

    Please help me print some text in an OpenGL window !!!!

    The flickering was probably because you use double-buffering...

    As for the font size - are you sure that you are re-creating the display lists? You're using bitmapped fonts, I think... I don't remember which tut is which. You need to re-create the DLs for a different font size.

    Calls to wglUseFontOutlines() and wglUseFontBitmaps() always map the currently selected font in Windows to a glyph whose cell is 1.0 x 1.0. This is regardless of the size of the current font.

    What this means is that to change the size of the font you should use glScalef() after drawing the text.
