I have entered the lighting challenge a few times in the past with POVRay:

Hmm, this is very interesting. Wouldn't it be great if a Pover won
something.

I guess it also prevents having twelve nearly identical Minotaur entries.

i spent some time pondering which whould be the drive wheel, the model
looks as if the higher one has a drive chain or something

A *quick* render. I have made it very shiny!

Ahhh so it is manual, I thought I was heading down the wrong track doing it
manually becuase it is so much work!
Thanks for the info, much appreciated!

It is much work and is not really the "right path". But is also as much ego
boosting as assembly programming. ;)
These things are called beveled edges in the polygonal world and come out as
fluidly and painlessly as pouring milk in a glass... I wish there was some
automatic way of doing them in regular CSG, but that is really a very old
wish...

Hehehe, so looks like its the "only" path then :) Oh well, better keep at
it, the more I do, the more I find little tricks here and there that make
things easier. Pity it makes my code such a monster to read, I might have
to start using include files more often...
Actually while we are on the topic, how do people generally build objects.
Do you make your complete object first and then bevel the edges? or do you
do it piece by piece, making each piece right with edges before moving onto
the next finally finishing up with a completely assembled object?
I soft of start making the whole thing up first, then get sidetracked and
start bevelling and then shortly after I cant follow my code anymore :)
(even with stacks of comments)
Cheers Dre

The biggest reason I didn't model this as a mesh is because it's
currently impossible to use any proximity patterns with meshes. That's
right, impossible! Actually, if somebody can figure out how to get a
proximity pattern working with meshes, I would really appreciate it :)

A little of both for me, but maybe more of the latter. It's helpful to
declare edge radii in advance, so you can make a global change if you
decide you don't like the current look. I don't always do this, but it
really makes changing the code easier later on.
