    the calculate process of the coordiate ?

    I think , clip coordiate =ProjectionMatrix*ModelViewMatrix*ObjectCorrdiate ;
    then NormalizedCorrdiate= ClipCorrdiate/Wclip

    Window = NormalizedCorrdiate *Width (or Height)
    but the outcome is error ?
    Who can tell me ?????????????????????????????????????????????????? ???????????????

    I don't quite understand what your question is. You can read about the calculation process in the OpenGL specification. Perhaps that will help you undestand whatever problem you're encountering.
