It looks great but I have to nitpick the lighting. Too uniform, use a
fade_power.
Otherwise I like the subject and detail.

You might be right, I made a "quick" test with intervals 3 and samples 10,10
on the left part of the picture. Took about as long as with samples 30 but
perhaps it was a but smoother. I wonder if I should work more with
aa_threshold and aa_level. OTOH are the default settings of 0.1 and 4 not
bad at all AFAIK.

Most of the scene is done with Isosurfaces. They are not that slow if the
formula is not too complicate.
>I wish, I would do such images.
You probably can :-). The most complicate thing in this pic was the sign.
But with some help over in p.newuser I got the imagemaps right and the rest
was not that hard. The woodstructure is just the function of a pigment I
copied from woods.inc with a flipped repeat-warp. The dog is a screenshot
from the poser3-dog (didn't want to bother with meshes this time) as another
pigment-function. Same with the text. Finaly I added some grooves between
the planks with another function.
The other Isos are just basic shapes (esp. rbox) with one or two
pigment-functions. Since I could do most of the cut-outs for doors and
windows by simple csg ('cause the beams cover the edges), the functions
remaind simple and fast.
Putting all together needed some time, but that's because I have not the
discipline to code first and render afterwards. So I make a test-render
after each single change which is quite slow, even if you concentrate on the
relevant parts.

Thanks!
I'll probably do a more detailed street in my next scene, but there was that
little of it to be seen with the current camera angle that I left it the way
it is.

You are welcome. There is no point in posting a picture if you don't want to
know what the other think about it.

Oh, I see what you mean. I tried a glow first, cause I hoped I could skip
the media for the haze. But it did not look right. More like a modern time
street lamp or such. And would have been quite difficult to find the right
colour for it, 'couse of the tinted glass and such (hm, maybe not THAT
difficult).
I didn't try flares yet 'cause I somehow don't like the idea. OTOH you are
absolutely right, that the low intensity robs some realism.

I used fade_power 2 and media_attenuation for each light_source in the
scene, as you can see at the torch. But I should probably have varied the
colour of the two lanterns more. Or did you mean something else?

It looks nice, but awfully slow...
The wall parts between the wood should IMO have a different kind of
roughness, some base level where the irregular structures are 'carved in'
would be better.
The wood looks neat, do you care to share the functions? I'm always
searching for new ideas for isosurface wood :-)

Thanks and yes. The big media-box takes most of the time. Without media and
Antialiasing it renders in about 45 min.

Well, I would imagine, that is the way concrete walls are. Since the loam is
thrown on the wicker-work, I think the outstanding irregularities are not
totally wrong. OTOH I have seen and lifed in so many differend houses of
that kind, that I think somewhere you can find about every wall you ever
want :-) But most important was, that it was really easy to achieve - just a
granite pigment with the colour_map a bit 'flattend' on a box.
>The wood looks neat, do you care to share the functions? I'm always
>searching for new ideas for isosurface wood :-)
It is stolen from the standard woods.inc :-) Something like this:
#declare WoodFun2=
function{ pigment{ P_WoodGrain8A
color_map{
[0 rgb 0]
[1 rgb 1]
}
scale 0.2 rotate y*94 translate y*0.1
}
}
#declare WoodFun3=
function{pigment{P_WoodGrain8B
color_map{
[0 rgb 0]
[1 rgb 1]
}
scale 0.2 rotate y*94 translate y*0.1
}
}
#declare Balken =
isosurface {
function { RBox
(x,y+noise3d(x,y/2,z)/30+noise3d(x,y/4,z)/40,z+noise3d(x,y,z/2)/40)
// Rounded Box
-0.005*WoodFun2(x,y,z) // Holz
-0.005*WoodFun3(x,y,z)
}
method 2
max_gradient 2
accuracy 0.01
contained_by{box {<-1.1,-0.15,-2.5>,<1.1,0.15,0.25>}}
texture{T_Wood8 scale 0.2 rotate y*94 translate y*0.1}
}
The scaling and the rotation made it look good. And as you can see, I added
some irregularities to tha rounded box, which makes the beams a bit
difficult to position (cause they are somewhat curved) but more realistic
IMO.

Really? It looks more uniform than that. Well it's still cool.
