IMAGE DESCRIPTION: 

The idea of the flood came to me almost immediately, when I saw the topic.

I guess the story of the flood is well known, so I'm not going to repeat it
here. It's found
in the Bible in the book of Genesis, chapters 6 - 9. If you are not familiar
with the story, you can find
it on line, for example, at http://rs7.loc.gov/nls/reference/bibles.html

The image does not show the events described in the Bible in the proper order.
What I wanted to show
was the contrast between what's above surface of the water and what's below.

There's another image at http://www.geocities.com/SoHo/Gallery/7241/ark14.jpg on
my webpage, that
has a cross section through the water, so that it's more clear how, in my
opinion, a city of the ancient
corrupt world might have looked like. The temple, or the high place in the
middle of the city, might have
been a place used by those people 'to burn their sons and their daughters in the
fire' 'as burnt offerings'
to their gods. This idea is based on events described in the later chapters
(Jer. 7:31, Jer.19:5, for
example).


DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 


The image was created entirely in POV-Ray. It was slightly gamma-corrected (it
seems the monitor on
my home machine is fading away...) and converted from TGA to JPEG in Photoshop.

RAIN:
I posted a question 'How to model rain in POV-Ray?' to IRTC-L mailing list.
Thanks to everybody who
came up with suggestions, that was really useful!
Finally I made it as a number of planes in a #while loop with a bozo color_map
with highly transparent
colors, scaled significantly more along the y-axis and rotated -30 degrees along
the z-axis. In order to
blur colors I used a small amount of normal bump pattern scaled and rotated the
same way as above.
All the planes had the ior of 1.33 (water), and were clipped by a plane in y
direction, to avoid
interference with water

RAINBOW:
Is a modified standard POV-Ray rainbow.

ARK:
Made according to my understanding of it's description in the Bible. I compared
a few versions in the
three languages I speak fluently.
Modelled in Rhino 1 beta, and exported as a number of triangular mesh objects,
each object in a separate
*.inc file. The logs forming the roof were created on basis of the lines made in
Rhino, exported through
DXF, and then manually edited.
The ark has quite complex textures.

WATER:
A CSG merge object between a heightfield made in POV-Ray and a huge sphere
(should be the radius
of the Earth plus the thickness of water, but I did not use exact values). I did
not scale the heightfield
much along the y-axis to keep the underwater city still visible.

CITY:
A complex CSG made in POV-Ray text editor.

The source is not included since the triangle meshes and the heightfield
are too large. If you are interested in the source code, please email me.

Best regards,
N.B.
