Hi folks,
haven't been around for a while, I've been glued to this
scene and I guess it's my first serious try, (learnt a lot from doing this
one).
Firstly, it's a 3.1 scene, but when I rendered it in 3.5 b6 it turned out
a lot darker than the 3.1 render, any idea's why?
Secondly, having said that, this is the 3.1 image.
A few questions if I may.
1) How can I get a nice glow around the street lamp emanating downwards?
2) I'd also like to get the headlights on the cars coming down the valley
to 'beam'.
Any idea's?
3) How do I get 'radial' to work? I tried it on the barrell but couldn't
get it to work.
What am I missing here? Also, what can I use to put the 'bands' on the
barrell?
I believe that there are two (from memory)?
Anyway, hope you like it and comments are always welcome.
~Steve~

For the car headlights to be visible and to get the "glow" around the
streetlight, you would probably use scattering media, though in 3.1 that
would slow it down a lot. Another thing- if you do use scattering media make
sure all light sources have a fad_distance parameter.

If you're using radiosity, I think it was changed in 3.5b in such a way that it
would darken the scene, depending on settings. That's the only thing I can
think of that would cause the difference. Of course, I'm no expert. I just
started playing with radiosity a few days ago.

See Malhalis's reply

Well, first, it wraps around the y-axis. Which I assume you're trying to do,
since you're talking about the barrels. Second, in order to get multiple
stripes, you need to use the frequency keyword with the number of boards in the
barrel as a parameter. Then play with the settings until you get what you'd
like.
A real simple example (see attached image):
cylinder
{
0, y * 5, 2.5
pigment
{
radial
color_map
{
[0.1 rgb 0.25] // Gray
[0.1 rgb x] // Red
}
frequency 10
}
}
plane { y, 0 pigment { checker rgb <0.5,0.5,0>, rgb <0.6,0.2,0.2> } }
camera { location <0,3,-10> look_at y * 2.5 }
light_source { <100,150,-200> rgb 1 }
> What am I missing here? Also, what can I use to put the 'bands' on the
> barrell?
> I believe that there are two (from memory)?
To make the bands, I would scale the barrel slightly larger and cut slices out
with planes. You can make the bands only as thick as the metal (instead of
going all the way through the barrel) by differencing the barrel out.

I like the composition. The textures need some refining, I think. The house
looks very rough. The tiles need some separation from the grout, probably a
normal of some sort, at least. And for some reason the birdbath reminds me of a
cocktail glass.
It shows lots of promise, though

A difference between two cones could work.
BTW I think you would get a much better barrel, if you built it of
individual staves. It is not much more work.

If you use radiosity, you will have to expect very different results.

Scattering media would be a good idea, light fading is important too since
this would make the surrounding of the lamp much brighter in relation to
the foreground.

Again try media (and spotlights), if you want to avoid additional light
sources you can also try emitting media, although this will probably be
less realistic.

Wow a lot of work has gone into this, so some comments.
The floor tiles/bricks could do with a touch of shinieness to them.
The barrel in the corner seems to have a sharp edge around the top rather
than a flat edge which you'd expect.
Very good looking image. Some answers to your questions below too.
> 1) How can I get a nice glow around the street lamp emanating downwards?
Media in a cone, use a very faint white (transparent) along with the colour
Clear in your colour map or maybe a yellowish pigment along with Clear, and
give it plenty of turbulence (have a look at the source code to my halloween
image on my web page, I used this method for the glow coming out of the sugar
pot).

Same as above.

Experiment on a cylinder, and try rotating the pattern, again I've used this
on the coffee cups in my halloween image so d/l the source code and have a
look.

Like you say there's more than one way to do this, here's what I'd
probably try.
#declare Band_Cylinder = cylinder{<0,0.1,0>,<0,-0.1,0>,3
pigment{Barrel_Colour/1.1} // Makes it slightly
} // darker than barrel.
#declare Barrel_Bands =
intersection{
object{Barrel scale <1.05,1,1.05>}}
object{Band_Cylinder translate y*0.75 }
object{Band_Cylinder}
object{Band_Cylinder translate y*-0.75 }
}
#declare Full_Barrel =
union{
object{Barrel}
object{Barrel_Bands}
translate <wherever you want the barrel>
}
Hope some of that helps.

Oops that should have been:
intersection{
object{Barrel scale <1.05,1,1.05>}}
union{
object{Band_Cylinder translate y*0.75 }
object{Band_Cylinder}
object{Band_Cylinder translate y*-0.75 }

Thanks.

Yes, I agree, especially where the kids haven't trodden on them? Or
is it the other way around?

Ah, the barrell. Hmmm.... not what I was hoping to achieve mate, but
the SOR did come out near the shape... ;)

Thanks Steve. This was the first image that I've really tried seriously
with. I started with the birdbath thingy a few weeks ago, (remember the
crystal ball in the bath and Bill said to try a garden around it?) Well, I
tried that and haven't put it down since. I found that as the scene grows,
you get more and more into it, experimenting with all sorts of things and
you end up wondering what you can do next. This aspect, I like.
Some answers to your questions below too.

I was going to use this and then I saw your next message, so don't
worry I haven't wrecked anything, I'm looking forward to having a play
tomorrow night with it.

It sure did Steve. Thanks, and thanks to all of you other guys for your
