IMAGE DESCRIPTION: 


Everyone is talking about global warming, melting ice caps, dramatically
changing weather 
and floods all over the world.
This truly is a problem, but only a few recognize that our most important
resource is going 
to vanish: drinking water.
There_re already wars about water sources. Anyway, we_re using drinking water to
irrigate 
golf cources, gardens and to flush our toilets.
Therefore we won_t drown in a flood, we_ll die with thurst. 
That_s what this picture metaphorically stands for.

DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 


The source file is a joke... I created this image within 3 hours. I was just
experimenting 
with isosurfaces and at one point (which was a coincidence) the result
remembered me of a 
"round" desert, hence this idea.

For earth I used an isosurface with an image and a crackle pattern, finally
textured 
with an image map. I didn_t use a image with the real topography of the (empty)

oceans, because the planet would hard to be recognized as earth. Therefore a
flat 
ground for the oceans.
Secondary I oversized the relief a little for same reasons...

For the atmosphere I used a media which I slightly translated towards the light
source, 
because I disliked an emitting atmosphere on the shadowside of earth.
Additionally I tried 
to make it look really thin, because a loss of water would reverse the
greenhouse effect 
and volatilise the atmosphere at one point (like on mars).

The starfield is actually a skysphere with a bozo texture.

The moon is just a sphere with an image map.

I know that there is no chance to gain a good place with this image, but I hope
you_ll 
enjoy anyway... 

For any questions, please write me!
