Hehe, here's a plan: use OE to post in sections. Wait for someone to
complain
they can't look at it, someone else will compile and repost it for you, then
you
can cancel the originals...
***
hehe :)  ya . . . why didn't I think of that ?
I'll just keep 'em under 100K instead.

With AOL 6.0 they began a AOL Anywhere set of features to allow for access
via several optional methods.  They just sink their teeth in if you struggle
:-)
I've looked up the possibility of a ISP with a 1-800 phone number to forego
the need for local calls from anyplace but found none.
I currently have a year of free Dellnet by MSN which has a local number too,
as well as my cable modem ISP being local also.  So I get to choose from one
of the three, AOL, MSN, Charter Pipeline.  I remeber how it was trying out
NetZero and needing a expanded local calling area in order to use that.
It's hard to beat the big companies when it comes to accessibility, I agree.

Nice !

This image makes me want to do more Fibonacci images.

Maybe you could use area_light(s) to avoid the sharp
shadows from the letters.


BTW: What texture did you use for the letters ?

One of the standard Stones, no?

Started off as one of them but I made some changes . . .
don't recall what but it is in this incarnation:

#declare BW_MARB=
  texture {
    finish  {
      ambient 0.9//0.3
      diffuse 0.5//0.2
      reflection 0.1
      refraction 1
      ior 1.45
      specular 0.8
      roughness 0.003
      phong 1
      phong_size 400
    }
    pigment {
      bozo
      turbulence 0.9
      color_map {
        [0.0 1.0 color red 0.39 green 0.39 blue 0.39
                 color red 0.01 green 0.01 blue 0.01 ]
      }
      scale .75//10.4
      }
}

Thanks . . .

Yes . . . of course they affect the highlights on the beads too . . .
I did a lot of changes today for the finish of the beads . . .
changed to specular and some metallic to make them glow a
bit . . . kind of a pearl look to the light colored ones.  But . . .
I don't like how the darker ones look with that and the beads
in the shadow look completely flat.  So . . . more work to be
done.  My original idea was to have them translucent with the
lighting shining thru from the back.

  I do like how the Fibonacci pattern enhances the curves.

Here's what I used Dennis:

This started with some of Alf Peak's code in his post
"Golden Ratio" to p.t.s-f  31. Aug;
news://news.povray.org/39ad9be0%40news.povray.org

and then Tor's "Fibonacci Stones" image got my attention . . .
news://news.povray.org/39B44A76.2ECBA98A%40online.no

Here's his source:
news://news.povray.org/39B59A50.66F1BAA7%40online.no

I dropped back to using spheres instead of Tor's AntiBlobs
as I'm still trying to finger out how he's doing that ;)

The simplified code for generating a union of spheres and
projecting an image onto it is attached.  A big 2K
Tried to comment it.
You will have to provide yer own pic ;)

I think I'm in love. I like.

The pics OK as well, maybe a bit dark for me without tweaking the
gamma. Do you realy need assumed_gamma 2.2? Try display_gamma=2.2
whatever to match YOUR monitor, in your povray.ini, then use
display_gamma 1 in your pov file.

I agree on bead size, less than around 5 pixels diameter each is not
so good. Have you tried a single colour per sphere instead of an image
map on the union? Megapov has an easier solution for this than pov3.1

BTW Compuserve has global access, providing there is a node in your
area, and you only need your password. They are now under AOL so I
would guess AOL should have similar facilities? It does allow

 That's what my original intention was but . . . a bead for each pixel
really limits the size of the photograph that I can use.  Some small ones
would work but even at 400x400 . . . yikes !!!  So I just shot it at the
union and way very pleasently surprised by the result.
  And BTW . . . thanks for that Fib engine . . . way cool . . .

  The darkness was my fault . . . somehow had global finish in it for
this pic . . . fingered it out now and have control over the image
brightness.

Oops! Use assumed_gamma 1 in your pov file.
Sorry.
