IMAGE DESCRIPTION: 

Somewhere in the northern hemisphere... waterdrops are dropping
out of a tap, that somebody forgot to turn off completely.
Somewhere in the southern hemisphere... a desert, where water
is urgently needed.


DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 

This picture is NOT postprocessed to put the two images of the
sink and the desert together. Everything is rendered.
The kitchen-scene is edited by hand as pov-source. The only
problem was the waves in the sink. For this I wrote a
short program which generates a heightfield of a waveform.
This program can also generate heigthfield's with interfering
waves. It was originally intended for an other picture with
raindrops falling into a water surface. Maybe I'll post it as
second entry, but today is already the 31. October...
The desert-scene consists of an heightfield, made with VistaVue
2.0 (Demo-Version). It is exported as .tga-file and then used
as heightfield in POVRay. The sand-texture is layered wood for
little stripes in the sand and a second layer with bozo for the
sand itself.
The two pictures are set together in one POV-source. Each picture
is projected on a trapezoid. At the line, where the two pictures
meet, I have put a glass cylinder with an high ior and bumps on
it to get a smooth transition.
