Since this is my first post, I figured I had to take on the epic "Chrome
Sphere on Checkered Plane" that begins all good POV-ing careers. This
particular version uses scattering media (type 4), focal blur, blurred
reflection, and radiosity. Needless to say, it took a long time to
render (I'd hazard to guess it was around 20 hours for this resolution -
I'd give more precise data, but the computer crashed sometime after it
completed but before I got to access it again).
Because I'm impatient, some of the quality settings were inadequate. I
got rid of most of them with some simple GIMPing - despeckle tackled the
persistent focal blur artifacts that kept occuring quite well, but the
image isn't vanilla :( Name and date were also added with the GIMP.
Nothing else was changed.
Enjoy!

Nice image, but 20 hours seems a bit extreme even with all of the eye candy.
Care to post the source so that I can try it on my compy?

To think it was done on a relatively new PC too (PD 3.0GHz, 2GB RAM).

I'll tidy it up and post it to p.t.s-f in a few minutes.

This is one of the best RSOCP images I have seen in a while. I like the
camera angle and the tiles look really good. This is what raytracing was
made for..

Thanks! I tried to work on the "composition" aspect of the piece rather
than just cramming in features. That said, I used a lot of them, and
render times are known to increase exponentially with such applications.
I think what I've learned in my art class this semester has really
helped :)

Focal blur. It takes insane settings to make it look good...

Or just use a smaller aperture. Overabuse of focal blur is
out of fashion. A smaller aperture and consequently a more
subtle focal blur may give much better results. :)

It is a living scene: i like a lot the "touch and feel" of the floor
expecially.

Everyone loves the GIMP ;-) but there is surely a way to do it using only
POV-ray...
Nice work,

There is, but it would take forever. It's the focal blur, as was noted
earlier. I posted the source, feel free to experiment with it. Don't
expect it to render quickly, though.
