IMAGE DESCRIPTION: 

The sun rising over an empty snowplane shining through the - by exception of
some clouds - clear sky and a curtain of icicles.


DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 

In the beginning I had a complete snow coveres forest viewed through a window
with icicles hanging from it's frame in mind. But due to the fact the recursive
macros that should have created my little forest stalled my whole system
(although I set the rendering process to the lowest possible priority) and took
a little bit too long for my usualy almost eternal patience, I decided to leave
it out.

Since it took me more than two month (I actually hadn't much time for rendering
then) I had to leave out the window, too. Leaving the icicles and a snowplane.
I then thought about placing a little snowman into my snowplane, but that
didn't word because it just didn't want to appear together with my snowplane.

The icicles were created from a blob of cylinders that grow smaller as farther
they get to the bottom and put into a macro that places them next to each other
using random numbers for length and distance between each.

The snowplane is an simple isosurface (now I think I would have done better with
a more simple heightfield) and just lies lazy on my little planet

The sun is a very distant sphere with a lightsource within and containing a
light emitting media.

The atmosphere and clouds are also spheres containig light scattering media
