I've been wondering if the result you're after is anything like Norbert Kern's
'position finder' code from 2006. Thomas De G and I spent time in 2018 trying to
improve it...

IIRC, you first render a scene, then pick an x/y pixel position in that image
render and feed it into the code, and it gives you the actual 3D position in the
scene that the pixel corresponds to.
I have to admit that I haven't revisited that code since then, so my memory of
what it does is a bit hazy. I need to re-read that post myself! I do know that
Thomas and I also posted image examples at the time, of our work-in-progress.
