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.
