Originally rendered at 5000x2000 aa0.3, took 12h 48m 59s and 76,767,231
bytes.
Once again I forgot to add the horns on top of the locomotive (the
actual one is missing them too). And the "random" function seems to have
made fairly un-random results yet again.
I'm going to have a lot of work left on the bridge and landscape. I have
the bridge pretty much done, but it hardly has a detail level anywhere
near the train itself. I think I'll have the camera at one of the ends
over a pylon, it's much easier to make realistic concrete than steel. I
tried a turbulent bozo texture to make rusty spots but it doesn't look
quite right. And I can use roundprism().
BTW to make the bridge deck I have the long box with the cross braces,
but no braes on top; strips are placed across thw width of the bridge at
the height where the side crossbars meet and cross over, so that the
part above serves as a guardrail.
The geography will be all wrong of course, bridge is in France. :)
Any tips on making the landscape?
Comments on ghost train?

The engines should have different numbers on them. Good choice of bridge
famous, same guy who made that tower in Paris. It doesn't have to look like
steel does it? Most steel bridges are painted.

Yep. That'd be a bit of work though, I suppose I could split the larg image_map
into the KCS part and the number, and make multiple number ones. The cars all
have the same number too.

Tnx. Yeah, it is painted, but I wanted sort of a weathered look. Eiffel BTW.

I like it, but it really needs at least this size to look good. The final
scene will probably render quite slow.

IMO rough rust is quite unnecessary in this case. either paint it or make
it just dark brown with some variations and a granite or small bumps
normal.

I would use a heightfield, because an isosurface is probably slower and
more difficult to adapt to the bridge. You might consider using 2
different heightfields for both sides of the bridge.
Trees would be interesting too, but i would keep them far away from the
camera so you can do them with simple image maps.

Yeah... still don't have that Athlon yet either...

Yes, but at any rate the texture is hard to get detailed enough. Maybe just a
grainy normal like a matte finish paint. That crayon orange is hard to match
too.

Yep, but I'm gonna need precise control over the height at certain points.
Ugh, time to dig out HF-Gen or whatever it was I wasn't very good at using.

I was thinking just spheres with transparent leaf textures or something over
some very simple branches.

I just wanted to avoid trying to spell Eiffel, I would be in bad shape if this news
composer didn't have a spell checker.

HF-Lab (http://www.best.com/~beale/) is quite a good program for that
although the actual simulation algorithm is somewhat limited. Anyway it
works fine for precise control if you don't fear a somehow mathematical
approach.

Just claim it is a side effect of genius concentrated in one area.
