I don't think that is what Istvan is looking for. The problem, as I
understand it, is how to go from

light_source {
    <0,0,0>
    translate <0, 0, SunDistance>
    rotate <-Al, Az, 0>
}

to an exact position: light_source {<x,y,z>}.

Although I've put together the sunpos.inc (I needed it badly) my math is not
as good as it has never been before

Sorry I cant help you on this, maybe someone else?
