I think my first experiences playing around with POV were at around v2.1.
However, I have mostly used it like a 3-D CAD thingy, to visualize some
ideas and such. So getting it "realistic" wasn't something I strove for.
This image is of a Steam Loco I was working up for doing a small animation
to amuse my small child and grandchildren (yes, I had another one very late
in life).
So far I am putting it together piece by piece, just trying to get a
pleasing look from a proportional standpoint. There are lots of details to
go, but I got to learn a bit about prisms, bezier splines, and am looking
forward to putting all sorts of neat tubing together on it with sphere
sweeps and all.
Please be gentle in your criticisms, many parts are just initially there as
a simple box or something for the sake of something being there, and not
just empty space.
I've got to get more of a slightly reflective steel surface texture rather
than the silver I am using. Anybody have any suggestions for the rails and
the wheels?

I think we are all some kind of newbie :-) So much to learn!
I think your loc is cute, and you should pursue in the same direction.
A few comments perhaps. Imo, the rails are too shiny (too much reflection).
Make them a bit darker and perhaps more rusty? The weels have no flanges, is
that correct? At least, I cannot see them (reflections?), but adding them
would be easy I suppose.

As someone who was once a small child fascinated with trains, I like the
picture. And as another POV newbie, I like seeing other people's
prototype works.

I think the front of the train looks a little skinny, especially right
above the front wheels. One cow or even a penny on the tracks and that
might bring the boiler down into the ties. I like that you put the bolts
on the bracing straps. The more I look at it, the more it looks like a
toy I might have had.

You could either texture the tracks and wheels with something that would
look like a hammered surface, or reduce the reflection and try upping
the diffusion. One of my favorite metal textures uses very low
reflection, 0.25 or so, .7 diffuse, and just enough ambient to make it
sparkle. Then change the normal block to get get the right surface
texture, either hammered or stressed, and phong highlights to make it
look polished. If you'd like to see it, I can dig through some files to
find it.
I can't wait to see what direction the image takes next.

Thank you for your comments, Thomas and Sabrina.
I got to do a little work on it. It might not seem like much, but there were
major design changes to the boiler that required numerous other adjustments.
Thank God I started out writing most of this scene based on parameters !
One of the things I love about POV is that you can write a scene so that
when you increase a length here, other objects that are dependant on that
length can automagically adjust.
Anyway, next things to work on are the domes, bell, whistle, guide and drive
trucks, cowcatcher, headlamp, fixes to the cab, pipes and tubes, signage and
whatnot.
This is fun! (but my wife thinks I'm crazy!)

I just discovered that your locomotive comes originally from the
PaintShopPro picture tube :-)
Nice!

I really like your first image! It has a "minimalist" look to it (in the
best sense of the word.) Even the camera angle is "just right." The image
reminds me of the painter Thomas Hart Benton's work. Or even Rene
Magritte. (Did I spell that right?) Personally, I think that adding too
much detail would spoil the effect. To me, it doesn't seem to need
"realism," in the sense of POV photorealism. Oh, and I like the original
engine shape better, too--those different-sized tubes just look more like
an old-timey train to me.
Some stylized puffs of smoke would be nice.
Making a POV image for your child and grandchildren is a wonderful idea. It
kind of puts the entire process of POV work in perspective. Many of us out
here work at trying to attain higher and higher levels of "perfection" in
our images (whatever that means.) Perhaps we should take a step back every
now and then, leave the technicalities behind, and just have some fun with
the program, as you are obviously doing. Your image is actually quite
inspiring.

Reminded me of a train I did for a profect a few years ago. The app needed a
little banner sized logo so I put a low detail train together (think the logo
only ended up at 120px high)
Anyway, this is what I ended up with.

In response to Glyn and Kenneth,
Wow, thank you for your kind words.
I was not expecting to be complimented much, let alone called "inspiring" !!
I was trying for the toy-like thing, but decided the heavier boiler was
better.
I need to add more details, things like the linkages, the whistle and the
Bell are absolute musts for a steam locomotive, Don't you think? And they
will make animations so much more interesting from both a visual and
modelling perspective!
Looking forward, I made the rails out of a prism, but can't figure out how
to get them to work for a curved section of track. Any ideas?
Randy

Same way as real rails on a real track... shorter straight sections end to
end at a slight angle.
Somewhere I have a macro I wrote to make curved track from straight rails,
but that was a hard drive failure ago... I'll have to scrounge around some
old disks to find a copy.

"bend.inc" from Chris Colefax (written back in 1997) should do the job.
