Hi all,
Someone sent this file awhile back, forgot who.
Who ever sent it, can you send me the source code?
Thanks
Brian

That was me.
I'm sorry, but I don't have the actual code that moment (it is stored
in the computer at my girlfriend).
But I can try to find something similar... <wait a moment> seems to be
the same. see below...
It was made just as a background for some testscenes. You should
render with povray3.1g - it looks quite different with 3.5beta (due to
the changed noise_generator, I think)
/// start
plane {y,0
pigment {
spiral1 3
turbulence .2
color_map {
[0.0 color rgb 0]
[0.3 color rgb <.6,.2,.8>]
[1.0 color rgb 1]
}
scale 30
}
}
camera {
location <0,8,-15>
look_at <0,6,0>
}
light_source {
<-100,300,-200>
color rgb 1
}
/// end
... simple, isn't it...

You can always use noise_generator 1. The result should be pretty the same.

I know, but in this case it wasn't somehow.
At least it wasn't looking that way.
Well, I can't proof it, but in my mind the source was pretty the same
as I posted a moment ago (except the look_at) - and it's looking to
swirly compared to the picture posted some days ago. (not tested with
povray3.1 though.
thanks, anyway.

You're right. Here are some images for comparison:
1) Rendered with POV-Ray 3.1g
2) Rendered with POV-Ray v3.5 b7 noise_generator 1
3) Rendered with POV-Ray v3.5 b7 noise_generator 2
4) Rendered with POV-Ray v3.5 b7 noise_generator 3
5) Rendered with POV-Ray v3.5 b7 noise_generator 1 +a0.1 +am2 (really weird)
The three noise_generators in POV-Ray 3.5 look pretty similar. Noone looks
close to the 3.1 version. Now I understand why I had so much trouble while
converting one of my wood textures from POV 3.1 to POV 3.5...

I did some other tests, and I have to say that with spiral1 noise_generator
1 and noise_generator 2 are absolutely identical.

maybe one should note in povray.b-t or maybe it's due to the broken
agate (must be a wild guess - what does spiral1 or turbulence has to
do with that?).
But I'm falling asleep now - it's already tomorrow.

Ok, reading the docs I can say that they shouldn't be so different. But the
problem remains: why 3.1 and 3.5 (noise 1) versions are so different? And
why using aa method 2 produces those weird artefacts (even at high
resolutions)?
