A room with curtains and other semi-transparent thingumajigs illuminated from
behind.
This shot uses some brand-new experimental POV-Ray 3.7 beta code, in an attempt
to show off, interacting with photons and high-depth radiosity (4 recursions,
though 2 would have sufficed). No media involved whatsoever.
50 minutes total render time on a Core i7 2.7GHz Quad system, mostly due to
radiosity and photons.
The POV-Ray patch allows surfaces to pick up illumination from the back side,
similar to the "double_illuminate" feature, but capable of
interoperating with photons and radiosity, as well as allowing to control the
effect's intensity.

Spectacular! Can't wait to see this in the 'live' beta.

That looks really good indeed! Excellent work.

Seems to make some decent fake subsurface scattering as well.
The left one is a backlit-only 100% white sphere, with a smaller sphere of the
desired color embedded inside; radiosity was set to 3 recursions.

I think that's how blender implements SSS too, except it puts the white
solid inside and the translucent color over the top. (I'm guessing just by
looking at it doing the actual rendering.)

Looks pretty nice! Do you think this patch will make it into the
official releases?

I can't say for sure (that'll be ultimately up to Chris Cason, who is currently
busy somewhere abroad), but I expect so. It is actually quite an easy and
straightforward change, with not much risk of breaking any of the existing
stuff (there's probably more lines of code in the sample scene than in the
patch :P) and I think the test shots clearly prove its potential.
So yes, I'm quite confident it will be released as an experimental feature in
beta 34.
Looking forward to seeing what all you guys out there will make of it.

Looks realy good. Any timeline to it's inclusion into a future beta?
