Stunningly realistic! I especially like the 'fur' on the couch--that's an
interesting pigment pattern.
Really nice work, both the lighting and the architecture.

Nice!
To me, the finish on the wood flooring makes it look more like vinyl
(due to the significant reflection) than wood, but there is a fine line
between polyurethane coating reflection and plastic looking.
I'm impressed by the molding on the baseboards.

I'm sorry, but this is just an image_map preprocessed with The Gimp
(using the furry filter from Gimpressionist).

Thanks, but the architecture is all from Chief Architect, I didn't model
anything, just tweaked textures and lighting.

Yes, it looks like a fake wood made out of vinyl... :) Wood reflections
should be more blurry, but I still haven't found a way to mix the wood grain
bumps with the blurred reflections trick.
> I'm impressed by the molding on the baseboards.
It's all Chief Architect... I did zero modeling there.

Freshly varnished floor using those ultra-gloss, or the socalled "diamond"
finish, urethane varnishes can be that shiny.

Seems to be a current craze, all that super-glossy stuff: Flat-panel TV frames,
laptop displays, floor varnish... what's next?
Yuck!

Well... the laptop display on the desk isn't shiny enough; I cannot see the
reflection of the wall, the lamp, or the topmost fruit. Also, I cannot see
myself reflected in the painting, the wall, the electrical outlet, or the smoke
detector. C'mon, Jaime, get with the program!

The trend began when suddenly all icons in modern desktops turned out hyper
glossy. My monitor has a label which reads "Piano Polish". :D
well, I don't have much to complain, it's shiny and we all RSOCP lovers should
enjoy it. ;)

Oh, yeah! Darn good job. Though I think the relation in brightness between the
glowing wire and the illumination of the table isn't so good - the wire should
be much brighter.

I thought most of us had already gone beyond that level ;)

That's easy - just use an averaged normal_map
e.g.
#declare bump_mapping =
normal {
bump_map {
png "wood-bump.png"
interpolate 3
bump_size 10
}
rotate x*90
scale 100
}
#declare micro_normals =
normal {
bumps 0.5
scale 0.001
}
plane {
<0.0, 1.0, 0.0>, 0.0
texture {
pigment { rgb 0.3 }
finish { reflection 0.8 conserve_energy }
normal {
average
normal_map {
[ 1 bump_mapping ]
[ 1 micro_normals translate <rand(s), rand(s), rand(s)>*1000 ]
}
}
}
}
Cheers,
Edouard.

Opps- ignore that translate statement (it was from the looped version for adding
lots of averaged micronormals).

Thanks, but I was referring to the "averaged big normals" trick, not to
the micronormals one... :)

Oh, I see.
Well kind of anyway - I'd really thought the two were more or less equivalent in
what they were doing per pixel.
I've done a texture averaging version of the averaged big normals as well - see
http://news.povray.org/povray.binaries.images/thread/%3Cnews.povray.org-AB5CC1.09303823032008@news.povray.org%3E
You create an averaged normal, then blend together a whole bunch of those in an
averaged texture.
I used sin() and the number of blur samples required to get a really smooth
blend without the usual random jitter noise.
The code (or something close to it) for that was:
#declare BlurAmount = 160;
#declare BlurSamples = 20;
#declare tex_A =
texture {
average
texture_map {
#declare i = 0;
#while(i < BlurSamples)
[ 1
pigment { tex_pattern }
normal {
average
normal_map {
[ 1, gradient z
bump_size
(-BlurAmount/2) +
(BlurAmount*sin(i/BlurSamples) + (rand(S)*
BlurAmount *0.01))
scale z*100
translate z*50 ]
[ 1, wrinkles 0.07 scale <2,1,1> ] // Or bump map etc
}
};
finish { reflection 0.08 metallic }
]
#declare i = i+1;
#end
}
};
Is that closer to what you are after, or am I still not fully understanding it?
Cheers,
Edouard.
