IMAGE DESCRIPTION: 
    I've submitted many snow-based images to the IRTC, so my
heart slightly sank when I saw the topic. However, all my previous snow images
had been fairly festive and/or fantasy based, so I thought I'd go for something
a bit more mundane and harsher.


DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 


Lighting: No lightsources, all light is via radiosity from the sky.

Sky: A simple grayscale pigment applied to an inverted sphere. A second sphere,
slightly smaller, fades from rgbf 1 to Gray25 in an approx. -z direction.

Tree: Generated via a macro that stores junctions in an array - vaguely based on
a lightning macro from a couple of entries ago.

Wall: Another macro, stacking irregular iso-surface blocks on an undulating
object.

Snow: The snow on the wall and tree is placed by another macro using trace. The
snowfield is a fairly basic iso-surace.
