Hi Paul,

thank you for further elaborating on your goals.

I took a quick look at the paper [1], but I am afraid that I would have
to think about it some more before I even know whether I have an answer
or not :-)

It seems like it involves some kind of multi-pass rendering technique,
which I do not know much about.  Maybe there are others with more
experience who can help you there?

Unfortunately I do not have the time right now, but maybe I can try to
have a closer look in the next days.
