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.

Pretty. Looks like a milky plastic.

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!
Michael

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 :-)

This is very beautiful! :)

I like the warm textures.
