That's true but it's not the right effect, and media takes too long to
render (while it can be used to make the effect). What I was saying is just
make it an entirely separate feature to media while being in the interior
statement... (because it's like media, but it'd be a separate algorithm to
calculate it...)

This is what I meant by making it adjustable. Double_sidedness just mean you
can see the shading of the other side through the object, right? You should be
able to use filter along with it.
It all depends on how far they go with it. Perhaps it could be made into
something like irid, where you would get brackets and all kinds of cool stuff.
How about:
double_sided {
amount [float]
color [vector]
}
Filtering and transmittence should be part of the color and be seperate from the
double_sided keyword. Translucency is just filtered opacity really. The color
would specify the color of the lighted portion of the other side of the
surface. The amount would be the brightness. I don't think a shadow color
would be neccesary, but maybe that could be thrown in.

I agree with what you said except for:
> Translucency is just filtered opacity really.
Because it isn't... remember translucency is depth dependant...

Filter and transmit would be, too, in RL. In POV you just have to add light
attenuation to the object for this to happen.

True, but the double_sidedness would be a fast trick. Depth could be
simulated with nothing more that a varied illumination from the other side.
What I'm thinking of is like a leaf or a curtain. If there was a way to
specify how much of the illuminated side of the surface shows through, things
like the viens in a leaf or the weave in cloth could be simulated.
Perhaps an opacity_map could be specified within double_sided {} :)

As I see it, it's not the fact the POV in written in
C that makes it troublesome to provide a patch. It's
the monolithic parser - you can't add parsing functionality
without hitting the code for every other type of
primitive. I'd like to see some work towards
modularising the parser. I think it can be done...

I'm going to have to start searching for this motion-blur patch and
docs.. Hmm, will check Twyst's site first...

Oh boy. Calms down to avoid calling Nathan "God". OK, I'm ready.
You know, that idea isn't half bad. I could seriously make use of that
:)

You'll find it there. It's not on my website anyway. But before you
can convince me to put my web site in a sig line, you'll have to convince
me to have a sig line.
