Hum, I don't think I get your drift here.

Do you mean: "Why would someone spend 20 years
of his life basically painting the same painting over
and over again?"
Or, as a pretty much Blue Chip artist do you mean:
"Is he only in it for the money?"

Or...

No, I meant why paint circuit boards.

Never mind. I think I found the answer. The guy is a nut case.

I know a lot of SCA calligraphers who show their work to each other, and
everybody complains, "Why is your stuff so beautiful when mine sucks?"
EVERYONE says it!

Except for the egotistical, black-turtleneck-and-beret-wearing,
clove-cigarette-smoking, espresso-drinking goateed beatnik wannabe's
(present company excluded ;-), most artists are convinced of their own
inferiority at art.  This has mostly to do with the fact that you are
all to familiar with every last flaw in your own work (after all, you
spent hours working on it), but most people (including other artists)
won't be nearly so cognisant of your failings.  Hence, you are your own
worst critic.

Basically, shaders are functions written in the RenderMan Shading
Language
(a language that on first inspection looks very similar to C) that
explicitly describe the interaction between light and some element of
the scene being rendered. For instance, there are surface shaders (which
return the color of light reflected from a point on a surface),
displacement shaders (which allow the surface of a solid to be modified
in some algorithmic manner, such as regularly-spaced dimples or bumps),
volume shaders (which modify the characteristic of light passing through
a volume of space, the interior of an object, et cetera), and others.
Their power comes from the fact that shaders allow the artist to
describe
*exactly* how the light interacts with a surface, how light is generated
by a light source (light source shaders), how a surface interacts with
reflected light (by calculating intensity, direction, color of reflected
light), and so forth. The interaction need not even be realistic; you
have
total freedom in your calculations.

There is a rather significant learning curve involved in using shaders.
I'd recommend "The RenderMan Companion" by Steve Upstill as a start.
It's ten years old, but it's still considered the classic beginner's
text on RenderMan, and it gives a good overall view about what shaders
do.

What's all this? If that is the challenge, I've already lost!

It was a joke son.

I picked a topic that I know that I am intimately familiar with and no
one else would be.  Gives me that winning edge.

If the topic were "A Scene Developed with only Matematical Constructs"
I would likewise be at a severe dissadvantage.

If the topic were "Poser figures in Pov" Gilles and Mick would have the
advantage because they own a copy of Poser and I don't.

Count me in. Look at what I did with printed circuit boards...
http://www.synaptic.ch/Greve/gtran/tran.htm
http://www.synaptic.ch/Greve/gtran/tran2.htm
(these pages need Flash)
These objects were made for a collective "installation" 2 years ago.
I didn't know these things were so hard to break and tear apart (got a few
blisters after that)...

They are different :)

Tougher than most people would give them credit for. We use high
speed routers with tungsten carbide router bits to fabricate them
with.
