This is a somewhat modified version of the
image I posted to this group 7. Nov. 2000:
"Toroidal iso-noise => Larger with wrinkles"
http://news.povray.org/povray.binaries.images/13131/87784/
news://news.povray.org/3A076749.A8600675%40online.no
This time I have modified both the surface and
the pigment by a function that are controlled
by a "wrinkled" noise.
What do you think of it ?
Is it too noisy now ?

Maybe you should smooth the background with some fog or so.
I have another suggestion, but you won't like it: radiosity. ;-)

Not really. Great job!

Caves - stalagtites-n-mites; OzLand forest fires; some tunnels you get
in vulcanology.
Beautiful pic as usual from a reliable source ;-)

Fantastic.
I also see the surreal forest like Jaime. It almost reminds me of the older
works of Gilles.

no its not too noisy at the resolution it needs to be seen at:
I'd assume at least 1024x!
Nice image!

Yes, that may be a possible solution.
- But I'm not familiar with POV-fog at all...
In the "Toroidal iso-noise" image I tried
to make the background darker by using a
fading main light source.
> I have another suggestion, but you won't like it: radiosity. ;-)
I wonder how radiosity will look like with
all those "columns" blocking the light.
I'm afraid that the light won't "reach" very
far away from the light source.
What do you think about that Christoph ?
And where would be a good place to put the
light source ?
(In the scene posted I used no_shadow for
the iso-surface.)

Thank you. That's a great compliment !
I went to his site to have a yet another look
at his fantastic images. He has added some rather
new and nice images (and other stuff).
While looking through "the book of beginnings",
I found these two images that had some simi-
larities to the image I posted:
http://www.oyonale.com/ldc/english/herd.htm
http://www.oyonale.com/ldc/english/maesta.htm
And maybe this one:

Is OzLand the area in Australia that have
all the forest fires these days ?
If you know of any web pages about such
vulcano tunnels, can you then please point
me to them ?
> Beautiful pic as usual from a reliable source ;-)
=) Is this a little hint for the source code ?

Thanks.
Friday I started a 1024x768 rendering of this
image on a 1 GHz PC. I'm looking forward to see
the result when I get access to it tomorrow.

You could 'cut off' the object just behind the camera so the light comes
in.

Somewhere at the side so you have nice shading on the objects.

Yes. I'm sorry that I sometimes use expressions that may not be
understood by non-english readers :(

I do not remember seeing any pictures on the web. The tunnels _do_
have a name, which escapes me. They occur in those lava flows which
are very liquid. The surface hardens fairly quickly but the lava
continues to flow underneath and eventually forms these tunnels. I
have only seen them on TV.

No. I remember playing with the source you posted for the November
image and I must still have it on my HD somewhere :)
