I think I have found a new way to simulate subsurface scattering(SSS). I 
have attached an image of an object with a yellowish diffuse and reddish 
SSS.

Can you tell how I did it? I did not use media or photons. I did not use 
double_illuminate.

Four stars to the person who figures it out.

Oh yeah, and I used nothing but POV-Ray version 3.5;

Hey Samuel. You deserve the four stars yourself for the stuff you've come up
with.

This one has a unique look. Layering of multiple surfaces? Perhaps including
a fade color too?

There's some irregularity of the shading in certain places (at corners of
the base) so seems that radiosity might also be employed for this.

That's really excellent. After you announce the winner, may we see the code?
I really would love to try the effect.
Great work (as always!)

Hi Bob, long time between greetings.

Yes, four stars for the introverted hermit :)

Close.....

Maybe a more advanced version of what I'm doing could clean that up.

Nope, way off.

Yes, of course! I will still need to fix a few things since it does not 
currently work well with radiosity (but it should if things go well).

I have tested it successfully in a number of situations so far, and it seems to
perform well.

Thanks!

Very nice.

A semitransparent, porous isosurface filling the interior?

Thank you Chris.

Nope, pretty far off. You know, I've tried doing it that way, but could 
never get any good results.

Here's a hint: this method doesn't take the interior of the object into 
account at all.

The image is really nice and gorgeous...
Is your method faster than "regular" sss ?

If you are comparing it to media, then yes, it's much faster.
