Is there a way to go: glBegin() glVertex(xyz) glEnd() then find the screencoordinate for that vertex?

I don''t think that there is, but I could be wrong. What do you need to do that needs you to be able to do that? I can''t think of anything that you would, but I''m sure there''s something...

You could use gluProject/gluUnproject. There is also a feedback (check out the specs) mecanism. But beware.. it is a *very* slow thing, try to avoid it if you can.
