the calculate process of the coordiate ?

I think , clip coordiate =ProjectionMatrixModelViewMatrixObjectCorrdiate ;
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.

where is the specification?
how can I find it ?

There’s a link to it from this site.
