AFter trying to catch up after three years (and having Outlook Express fight me
every step) I've decided to post one of my more recent renderings.
This is a fibinocci sunflower pattern done up in blobs and twisted about.
I'll probably be doing more postings in the coming weeks. If I could get a web
site up, I'd put stuff there. But, in the meantime, this'll work.
Questions and comments welcome (of course)
Michael

Fibinocci?! Do you mean *Fibonacci* (or even better Leonardo Pisano)?
BTW this looks really cool. Beautiful textures.

Ooops - missed that. Yes, Fibonacci. Of course, I've never heard of it called
the Pisano sequence :-)

Thanks! I was really happy with the background texture. Feels almost like
velvet.

IIRC Fibonacci (i.e. filius Bonacci: Bonacci's son) was just a *nick name*
for Leonardo Pisano.

Neither I have. But it seems like *Fibinocci* is a very common mistake.

I was just wandering how you did it.

The velvet? Pretty simple, actually. I used the following pigment within a
sky_sphere.
// A red velvet-like texture
// Michael D Johnson (red### [at] wvadelphianet)
// Use freely. But give me credit if you can :-)
#declare C_Reds = color_map { [0.0 Black][1.0 Red * 0.5] }
pigment
{
average
pigment_map
{
[1.00
bozo
color_map { C_Reds}
sine_wave frequency 4 scale 0.25
turbulence 0.5
omega 0.5 octaves 3 lambda 2
]
[0.90
bozo
color_map { C_Reds}
scallop_wave frequency 2 scale 0.25
turbulence 0.9
omega 0.75 octaves 4 lambda 2.5
rotate y * 45
]
}
}
Enjoy!

Thanks!
I guess it does, kinda. A lot of that comes from the reflection of the
sky_sphere, I think. The texture on the "sunflower" is:
texture
{
pigment { Gold * (mod(A, 0.5) + 0.5) }
finish { Shiny reflection 0.7 }
}
where A is the current angle within the sunflower, ranging from 0 to
radians(160000). Yes, there's 160,000 degrees of sunflower there :-)

its a cool image!
any idea how I could use that pigment in moray? (ie how do I use that in the
material editor?)

Seems almost alive! Colors are simply beautiful... a demostration that
you don't need a lot of strange colors to be abstract.

I'm flattered, but still, though I've had some success with advanced
animation techniques, my artistic accomplishments are nothing special and
deserve no greater admiration than those of yours and most other POV-Ray
users around here. :)

And I take every compliment very seriously. It's one of the reasons I've
decided to start posting here. It's one thing to have people who know
absolutely nothing about your tools say "That's amazing!" It's quite another to
have those who use your tools on a daily basis say the same thing.
I look at most of the work that gets posted here and am amazed. Then I'm even
more amazed when I'm able to do something that I think is comprable.
Thanks again for the compliemnts!
Michael

Thank you!
I tend towards simplicity in my colors and textures. Often I'll keep the first
quick texture I used as a test render. Of course, when they turn out like this,
well, why not?

Sorry, no idea. I did post the source, if that helps. I don't know if Moray
does averaged pigments. I've never really liked using modellers :-)

Well said! I feel exactly the same way and praise the day I found these
groups!
Happy tracing!

Strange. If the angle between nodes were 2pi/tau, seems to me the
`stalks' ought not to be so obvious: the ratio
distance to nearest neighbor / distance to third-nearest
looks too low. But maybe that's an effect of the blob arguments:
what are the component radius and threshold?

Actually, the reason the stalks are visible is because of the way the components
are shifted along the z-axis. I use the following macro to do the shifting:
#macro Z(A,I) #local B = A * (cos(I * 4 + pi / 3) + cos(I * 1.5)) / 4; B #end
where A should probably be better named 'R' for radius, or distance from center,
and I would be better named A, or total angle from center. I was just playing
around and was rather suprised with the results (as I often am with my work)
