I was trying to outline some shapes. For example lets take a sphere:
sphere {<100, 120, -85>,75 texture {clear_black}}
The trick I was given was this:
sphere {<100,120,-85>,85 texture {pigment {rgbt 1}}
interior_texture {red_frame}}
Its what you see in the top left here:

I soon learned I had to use the no_shadow flag to get what I wanted however.
And it wasn't till receintly I noticed something else was missing. The
reflection of the grid lines are gone from the black sphere. To get these
back I need to use the no_reflection flag as well. However when I do that
I lose the outline of my black sphere as seen in any reflection.
Ideally what I'd like to do is to say the larger r=85 sphere doesn't cast a
shadow or is seen in any reflection inside it however it does cast a shadow
and leaves reflections outside it.
Is there any way to do that?
Thanks,
Carl

I've played around with it for a while and have become convinced that
the answer is no. You either have to think of a completely new method
for outlining the shapes, live with the problems that you've got or
reduce the opacity of the outline shapes so that some of the reflections
can get through.

I can't answer your question, but that'a a nice pic on your front

I could render a larger one if you like. How big do you want? The text I
just added after the fact. It's not modeled.

Thanks. I can live with the problem. Considering it took me a while to
even notice I had a problem I'm sure most would never notice. Is there an
official procedure to follow if I wanted to recommend this capability be
considered for inclusion in a future version of POV-Ray? Conceptually I
think it'd be easy to add at the code level.
Thanks,
Carl

Yes, but I said "kill", not "kill for" ;)
A 350K file takes forever on my poor modem - 38 Kbps on an average day
:c(
Hows about jpeg instead, even minimal compression would be usefull
without giving artifacts.
Just my OT cents-worth.

Ahhh, my misunderstanding. I'll replace it with a jpeg soon. It's just a
place holder till I have a chance to work on my web page some more.
