The AO makes the whole scene look chrome, despite no reflections.

It's all CSG, master?  How did you do the side-front of the tractor, 
just above the wheels?  It looks curved in a way I can't figure out how 
to do with just primitives?  :)

This image should be posted in some CG webforums, beyond just 
newsgroups... it would bring much awareness for Povray.  Well, that and 
an indication for povray's Hall of Fame as well. :)

I had a little trouble finding this. Here you go:

It's all in French, but it's not much of a problem. I just took an 
example file and cut out the unnecessary parts to make it work for my scene.

Ah, good eye. What I had to do was intersect a cylinder with a prism 
using a custom curve, and then follow that up with a bunch of spheres 
following the same curve. Sounds easy, but it wasn't `:/

Maybe we POVvers should start entering contests or something. There's a 
steampunk contest going on right now, and POV is really good for making 
mechanical things :)

That model is begging to be raytraced :)

Thanks. Like I said, it's an imaginary design, made from a sketch. Of 
course I had some doubts about the design, but I thought I would try it 
out anyway. The idea was to have a machine made for going up small 
slopes. The design is probably unnecessary :)

Yeah, I rendered this with basic textures to simply display the model. I 
don't know if I'll go forward and finish the scene or not. Maybe I'll 
try out some textures, but the code is a little hard to navigate (it's 
over 1000 lines long).

Thank you for your comments. The lighting is like that on purpose, 
though I did not intend for the shadows to be quite so soft. It almost 
looks like the front tracks are treading on air.

Yes:

Would you be courageous enough to challenge all those polygon-pros with 
a little CSG wonder?  It's a very hard task.

I also heard this contest is offering US$220,000 in prizes!  Plus, it 
can be made in teams rather than individually.  Overall, an amazing 
oportunity in all accounts. :)

Thats the problem I seem to have when my scenes start to get somewhere, they 
become so huge i have trouble following them...

One question I have, how do you get those nice round edges instead of the 
sharp square edges you normally get when you difference stuff??  Do you do 
anything special here or do you manually round them off everywhere?

Cheers Dre
