Or glass filling the voids. Maybe a CSG nightmare but I sure would want to try
that.
I might never get a 3D printer but that's a great idea for a source of models.
Not that I know much of anything about it but I would expect most, if not all,
to be very "solid".

i've also thinking a media version ... shafts of light coming through
holes might look pretty cool too

that would indeed be a cool toy to have ... maybe i should buy lotto
ticket. if i win i could call into work rich and perhaps buy one or two!

I must confess I got it from the last image on the link above.
But on reflection, <g> maybe the other way round would take longer. ;)

Marble/subsurface.
Very cool.
I've always wondered how a uv_map(!) could possibly be constructed for the
texture of such a shape. Seems like it would have to be done in another
space/time dimension! :-P
What is the reflection(?) or thingy on the left side of the image? Very curious.

It does look like the reflection of a stained glass window. Especially
if you flip the image upside down.

here's a marble version ... there were some problems with the model that
were hidden by the procedural normal i used on the granite version. much
trial and error then smoothing the vertex weights around the cut outs
fixed it ... didn't even have to subdivide or use shade smooth. blender
did do a pretty decent job on the uv mapping as well. i /do/ see a
couple of /hot/ pixels i think a tad too much translucency. a little bit
more work and i think this one's ready for a beauty run!

I like the texture and yes a bit too much translucency.
I appreciated the description and must read up on vertex weights. As I
have a model that is showing artefacts that Ctrl + N does not fix.

that's reflection of brick wall and part of window in hdr probe ... but
closer to object the floor is showing the translucency i was talking about

well i'll only take partial credit for that ... it's an image map.
getting the uv mapping correct was the challenge

Yes, I agree. Maybe it needs slightly 'blurred reflections.' That seems to be a
tell-tale sign of 'metal' (except for polished chrome?)

i'm pretty sure that'll happen in version 2.0 ... i'm already working on
it. i /had/ a doh moment with the procedural normal i'm using when i
realized that with the current uv map i /should/ have used warp { planar }

Sure did. I was wondering if those red hot pixels from before might be purely a
side effect of SSS or if somehow caused by a small amount of reflection in the
texture or external object (floor).
Apparently I never asked about it before, and I can't see any reflection in
either of the marble texture renders.
Not that the other marble looked too transparent to me, like what do I know of
marble in all its possible appearances, but I can see how this one has more
solidness or perceivable larger size compared to that.

nope ... it's procedural. the underlying pigment is a single color with
a touch of irid ( also changed irid_wavelength in global_settings to
that color ) for the normal i used f_ridged_mf

I like the brass texture too.
In fact I tried to reproduce it - here is my attempt...
Perhaps you want to correct my mistakes?
global_settings {
irid_wavelength srgb <254,182,89>/255
}
texture {
pigment {color srgb <254,182,89>/255}
normal {
average
normal_map {
[1 bumps
scale 0.0175
bump_size 0.2
]
[1 bumps
scale 0.35
bump_size 0.2
]

i used your rmf definition then tweaked the normal map for this version ...
normal {
average
normal_map {
[1 bumps scale 0.175 bump_size 0.15]
[1 bumps scale 0.35 bump_size 0.15]
[1 function { RMF(x, y, z) } scale 0.1 bump_size 0.125 slope_map
{ [0 <0,1>] [0.25 <1,0>] [1 <1,0>] }]
}
accuracy 1e-3
scale 0.05
}
... i think it looks like cast brass that's been worked a bit.

i also played some more with irid ...
irid { 0.1 thickness 0.25 turbulence 1 }
it's subtle but you can see it in a several places

Yes, it looks patinated.
Personally I love metal materials, but it's difficult to predict their behavior
in several scene setups.
Metals depend on their environment, reflections are more important than diffuse
settings. Metals show sharp contrasts between shadows and highlights.
Therefore I prefer hdr lighting or at least a combination of a normal
lightsource and hdr.
Here I took the nice rolly_sphere together with a more polished silvery metal
material:
#declare mtex =
texture {
pigment {color rgb <1,0.952,0.818>}
normal {facets coords 0.024 scale 0.1}
finish {
brilliance 2
specular 0.5
roughness 0.01
metallic
reflection {0.8 metallic}
ambient 0
diffuse 0.05
conserve_energy
}
}
#declare dtex =
texture {
pigment {color rgb 1}
normal {bumps 0.2 sine_wave scale 0.01}
finish {
brilliance 1
specular 0.3
roughness 0.03
reflection {0, 0.8 fresnel on}
ambient 0
diffuse 0.15
conserve_energy
}
}
#declare unnamed_material_ =
material {
texture {
pigment_pattern {
average
pigment_map {
[1 wrinkles scale 0.02]
[1 wrinkles scale 0.063]
[1 wrinkles scale 0.2]
}
}
texture_map {
[0.5 mtex]
[1 dtex]
}
}
interior {ior 2.5}
scale 10
}

It's improved only in the small sharp dented marks to me, but from afar I still
prefer the setting of your turbulence, making it look more like it has been
somewhat applied, or polished, looks more like it has a history of being
crafted, yet, combining the two would be perfect both for distant and close ups!
I hop I will be able to get a hand on the final code version so that if you guys
agree, I can share it here:
https://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Render/POV-Ray/Sample_Materials
Along the other great POV textures?

yep i'm a metal materials fan as well ... and yes you are correct adding
hdr is definitely the way to go because it makes for plenty of eye candy
in the reflections

lol ... i have a silver version too. copper looks pretty cool as well.
i'm working on a glass version but there have been some challenges.
something opaque behaves better in that the shape of the object isn't
lost. to that end i've been working on a milk glass version ... i'll
post if i'm able to produce something worthy. thanks for sharing!!!

here's a link to some pretty good hdr images:
http://www.hdrlabs.com/sibl/archive.html
i've been getting a lot of mileage out of papermill ruins E but playa is
also pretty cool. the apartment at the top of the list is great for an
inside env.
i prefer the ones where you can actually see the sun or light source.
basically here's how i place the light source. with the image on a small
sphere and the camera somewhere -z ... i rotate the sphere until the sun
spot lines up with 0*y then i use a crude grid at <0,0,0> that i rotate
in the x dir to get the elevation. a few hints ... the papermill ruins E
lines up at y*33 and x*30.5 so i use those as offsets in my env and
light source setup:
#declare Environment =
sphere { 0, 1 hollow on
material {
texture { uv_mapping
pigment {
image_map {
hdr "PaperMill_E_3k.hdr"
map_type 0
interpolate 2
once
}
}
finish { ... }
}
interior { ior 1.0 }
}
rotate y*33
no_shadow
}
#local R_Fact = 30;
#local S_Fact = 30;
considering the above the light source is initially placed <0,0,-29.9>
then transformed like this:
object { Environment scale S_Fact rotate y*R_Fact }
object { Key_Light rotate x*30.5 rotate y*R_Fact }
