screenx, screeny (screenz ?)

how does the screenx and screeny - functions really work (and screenz, for what reason?)?
They integrate some transform-function and ignore others (in the whole code).
i get illogical results til it works, so i want to know more about it.
very thankful about help

screenX/Y are just literally that--the on-screen coordinates. as mentioned elsewhere, since a screen has no Z, the value isn't useful except in comparison, because it's weighted against the distance away so that resolution in z decreases as you get away from the screen.
someday we'll have more complete documentation for these things, but for now we have the forum  |

( search the forum works quite good .. )
