OK . . . having no luck getting the pic here so . . .
will just send the spiel to see if I at least can post a new message.
If this gets here . . . then at least I'm on the right track and there is
some problem with the impage or my ISP.
If this message makes it, I'll try posting the pic with a reply to it.
Thanks for yer indulgence . . . I will get this figured out somehow.
--------------
Shamelessly lifted the code from Tor's "Fibonacci Stones"
and saw that it originally came from Alf Peake . . . thanks guyz.
This started out as an attempt to render a stained-glass window
with light rays streaming through but, as usual, I got sidetracked
when I came across the Fibonacci scenes here. So I decided to
see if I could project an image onto a pattern of blobs or spheres
and make them transparent. Haven't been able to get the .png files
working that way but . . . liked how the beads looked so moved on.
Opted to go for spheres instead of blobs so I could better control
the size and spacing ( I'm still workin' at understanding Tor's Anti-
Blobs ;) and used Alf's code to create a union of 3200 spheres.
Then just projected the pic at it. Didn't have to worry about using
a transparent background 'cause . . . I just kept altering the number
of spheres until the union included the portion of the photo that I
wanted. Just played with scaling and translating within the image
projection and altering the sphere size and spacing until I had what
I wanted. (many test renderings later ;)
Did it in POV 3.1 . . . couldn't seem to get the ambient lighting bright
enough in Megapov 7 . . . without bumping it from 0.3 way up to 0.8
or so. And I had to do that using the #default finish statement. Have
not been able to find how to add the finish statement into the image
texture. But I was tired by then so . . . will continue to experiment.
Also noticed changes in how the textures changed when I switched
between 3.1 and MP7 . . . is there something I need to change within
the INC files . . . interior statements for the finishes . . . ?
Originally was gonna do a background but opted to leave it as is
'cause I didn't want to distract from the image . . . and it seemed to
have a nice balance to it.
Rendered as 1280 x 1024 . . . knocked it down to 1024 to drop the
file size . . . it's still ok . . .800 really hurts it so . . .
This is my 1st pic post ever so don't be too hard on me . . .
And I have isosurfaces yet to explore and all of the MegaPov tweaks.
I do enjoy all of the give and take here . . . seems like a big family.
Y :)

Grrrrrrr . . . . .
My email server here is dropping me out when I try to upload
anything > 100K . . .
Tried to use AOL to access the group but they do not see POVray.org
as being one of their newsgroups so . . . ???
If anyone knows how I can use AOL to post here, please let me know . . .
here or in new users if that's better.
Will eventually find a way to post the pic here in this thread.
Even if I have to jjpg it to some small size.
Sorry . . . sure would like to get this worked out.
Thanks
Y

I like it: would like to see one with more detail - more beads?

You should not need email server or other things from your provider, just
set your newsreader to use news.povray.org as newsserver and it should
work. No provider should have the povray newsgroup on it's newsserver.
See the postings in povray.announce.frequently-asked-questions for
details.
Furthermore it should rarely be necessary to post pictures larger than
100k. When looking trough older posts you will recognize that most
pictures posted here are smaller. If you want to show a higher quality
(png) pict, you might consider putting it on a website instead and posting
the link.
Nice picture BTW, i remember some similar pictures, not with fibonacci,
using megapov's eval_pigment to display pictures. Who is Lea?

Well . . . for whatever reason, when I am in this town, using this ISP, I
can't
upload without losing the handshake or being disconnected. Now I don't
have that problem with any other ISP (I am on the road a lot) and I don't
have it with AOL. But I cannot figure out how to use the AOL dial-up with
newz-groups . . . they have there own list of them and it doesn't include
POV.
I have to do some sort of TCP thing and use their modems but I don't know
how to go about it.
I understand about the 100K or so size . . . and I agree . . . stashing
them on
a web-page and providing a link would be the best way. Just not enough time
in the day to work and play . . . and at this point, work is interferring :)
And in this case, the pic sure does suffer . . . and I want to speak to
Sander
on this too . . . he wanted to see more spheres . . . that's fine, however,
it is
all a balancing act. More spheres means smaller dia ones and at some point,
the visual effect is lost when the spheres are too small. Thus . . . the
reason
for rendering at 1280 for these . . . that was the point where they still
looked
good.
And . . . I have also imaged to other patterns . . . tightly packed hex
patterns
for example. But the thing about fibonacci is - it seems to enhance the
natural
curves when a photo contains them. Notice how the shape of the eyes and the
cheek and hair all seem to follow a series of spheres . . . any curved
object
can find a series of spheres that fits it and the eye is able to see that.
Hex
patterns tend to emphasize lines and diagonals and hide the natural curves
and actuall distort the eyes. These spheres actually seem to follow them.
So, when I saw the first image that I traced . . . I was hooked . . . just
seems
the way to go when depicting nature. I will also experiment with Tor's
anti-
blobs as soon as I can finger them out.
Did this shot for a friend . . . this is an old pic of a girl he once met
in France.
He's very pleased with how it came out . . . I've been promising to do
something
for him with it for a long time.
Thanks for the comments . . .

Thanks Sander . . .
I did a lot of experimenting and it ends up being a balancing act . . .
More spheres means smaller dia ones and at some point, the visual
effect of glass beads is lost when the spheres are too small.
I played with various numbers of them and altered the dia and the
spacing until I had the desired effect. Also depends on the photo . . .
and had to scale and translate the image to get the center at a point
where it didn't make a mess of some feature. Also, that's the reason
for rendering at 1280 - to bring the size of the spheres up to a level
where they could still be seen as beads. Each image will vary and
it took many, many test renderings until I found this one.
I'm pleased with it . . . will try to find a spot to stash the large one
and post a link to it . . . quite a different effect full-size. I can see
some artifacts in this one.
Now . . . back to thinking about stained glass and getting my .png
images to be transparent. Anybody have any info or hints on that ?
TIA

Yes I see now. There's one thing I did: changed the brightness upwards
in Photoshop. IMHO this was an improvement: I could see more of her
eyes, and the contrast in the darker regions was improved favourably
too, I think.

One of the problems I had was getting the image map bright enough . . .
I had to bump up the global ambient settings to have it show up at all ...
esp when I tried to use MegaPOV . . . couldn't seem to tweak just the
image map. Still trying to finger out why.

AOL is frustrating. You can suggest they add news.povray.org to their list
by going to the Newsgroup area but I think without enough demand for it they
probably won't. I asked for it there long ago. I always thought it amazing
how AOL intercepted my attempt at getting here from outside of the AOL
program, although only connected to Interent via AOL, using a newsreader;
the same error message would pop up that shows from within AOL saying these
news groups didn't exist or something.
So, I don't believe there is a way but one never knows for sure I guess.
