Haha, no, more a "Bob Ross Happy Accident". Just going beyond sensible with
scaling of blobs and I guess then you run into numerical problems.

Rather interesting object, will play with it. Reminds my fractals

It looks like we are on the way to the modern art gallery.
I call this artwork "Spring in NY", guess it will be sold

Hey - this is a really good one.
It looks like a white blood cell from Asimov's _Fantastic Voyage_!
Could you share how you achieved this result?
This looks like a good base for future modeling.
Maybe you should try using emission to see if you can get some nice "glow"
effects.
I could also envision giving it a green hue to simulate some sort of microscopic
plant cell, and maybe a (mostly) clear/ior internal region with some irregular
"organelles" to make it look like one of those microscope slide images.
Horton hears a who? :)

In the scene file in the first post use
sphere{0,1,-0.8 scale <1,0.00021,1> Point_At_Trans(Normal) translate
Normal*Distance*1.2}
inside the blob loop
and this for the lighting:
light_source{< -300, 3000, 0> rgb <0.3,0.35,0.2>}
light_source{< 3000, 300,-500> rgb .5}
light_source{< 700, 300,-500> rgb <0.4,0.2,0.0>}
light_source{< -300,-3000, 0> rgb <0.2,0.2,0.6>}
There is no control over the modelling, it is an intersection of many blob and
the blobs are scaled "thin". It would not surprise me if the result is also OS
dependent.
Here's an other one, from the same scene file settings: N24SY0.0001

I rendered without any change, using the commented line :
sphere{0,1,-0.8 scale <1,0.01,1> Point_At_Trans(Normal) translate
Normal*Distance*1.2}
Will try with the other options.

Added #switch(frame_number), a few #case(n)...#break and rendered with +kff7
First one : Rounded faceted sphere
Second : Sharp faceted sphere
Third : Pockmarked sphere
Fourth and following : It get fuzzy.

Attached is something like what I used - it produces the bottom part of
the attached image... The coloring comes from Ingo's light colors.
I don't have the original scene anymore as I was playing with this and
that. Plus, I was using my yuqk fork for which the "numerical issues"
are a little different the official releases of POV-Ray. This shown in
the top row of the attached image where on the left is Ingo's original
at 1e-3 and the same rendered with the yuqk fork on the right(*)
The biggest changes for the fuzzier results was not using the larger
positive sphere and changing the negative squashed spheres into positive
components.
Bill P.
(*) - Part of what is happening in the original posted scene is that as
we scale down in y, except for the edges, the negative components start
to cleave off little round bits of the larger sphere rather than blunt
it in a faceted way. The yuqk fork shows this a little better, because
it's numerical accuracy with blobs is a little better.

Thanks for sharing scene and detailed comments, right 'out of the box'
it looks completely different (attached), but I will try to tune it up.
Now I'm thinking about adding it and similar abstract scenes
to https://povlab.online in separate section - 'artifacts' :)

The one on the left could be further modified to produce some nice crater
impacts.

Using a scripting language for a ray-tracer means that puts in sliders that only
go from 0 to 1. Many values in POV-Ray can be set for the extreme.
Here's some abstraction animations, if you've not seen them before. It's mostly
a play with extreme focal blur combined with "bad" render settings:

Wow. Your first grayscale image (AND the colorful version) are really nice; they
remind me of hand-drawn charcoal sketches...just about the best I have ever seen
(from POV-ray or from *any* typical paint program, with its various 'artistic
filters'.) These images would make great science-fiction book cover
illustrations, as Bald Eagle mentioned. I am amazed that you were able to put
together some code to create such abstract and organic-looking ART.
Congratulations!
Don't lose or override the code settings for these two! ;-)

Very interesting, I like 0, A, C, f, M, and z. Colors and movements area
very smooth, guess they need some ambient music by Brian Eno like here:
https://www.youtube.com/watch?v=HI1raqxrUdk
Some of them looks like particles in my 'Fetch' scene:
https://worlds.yesbird.ru
I've included your scene in Povlab (1280x720 takes 7.7 sec):
https://povlab.online/?scene=art_1.pov
and now playing with it.
Just for info:
Ctrl-S - Submit for rendering
Ctrl-R - Hide editor
Permanent saving not implemented.

Sorry yesbird, I did not realize that the color version was your variation.
Nicely done! Both versions are really inspiring.
I need to get some time to play with the various versions of the code here, to
see what pops out.

I am only following Ingo's genius and can't stop playing

Try this service, it can save a lot of time:

Sergei, I've been meaning to ask you - do you have a method to upload image maps
for use in renders? Maybe some sort of "email attachment" style mechanism,
perhaps to a directory that gets wiped with cron job every N hours?
Or maybe a FIFO replacement system?

Hi, Bill.
Unfortunately, at present time no, I thought about it and can
implement one as simple html upload form if such function will be
demanded.
Right now, if you want, I can upload few image maps special for you
in personal directory and create separate scene with button 'BL' :).
Just send me them as attachments.

Hi, Bill.
Unfortunately, at present time no, I thought about it and can
implement one as simple html upload form if such function will be
demanded.
Right now, if you want, I can upload few image maps special for you
in personal directory and create separate scene with button 'BILL' 🙂.
Just send me them as attachments.
