Here I'm starting a collection of static and animated objects,
inspired by Roger Dean's artworks:
https://github.com/syanenko/pov-yes

Most of them will be implemented as parameterized macros for more
easy reproduction with visual varietivity. Everyone, who is passionate
on Yes and/or Dean's art can join this project and contribute whatever
he want/can.

As the first seed of this library I've rendered this short animation of
the breathing coral:

Comments, ideas and suggestions are always welcome !

I only got so far on the single-image photogrammetry of the ship - Applying
dozens of matrix transforms to the in-plane points of my trace and viewing from
several vantage points shows just how challenging a task it is, and just how
much what your brain thinks your eyes are telling you is there just .... isn't.

I'll probably have a go at figuring something out on paper and making it from
scratch.

That said, Roger Dean employed a lot of Egyptian imagery for Asia, and I have
all of my stuff I did with regard to the Giza plateau, the Great Pyramid (all
1.3 million blocks), the Schist Disk, and whatever else I have lying around.

Also see my recent post re: vase stl

As people know, I kind of work in fits and starts - long periods of inactivity
might be followed with a sudden burst of inspiration, followed by a need to just
take a break.   YMMV.

Hi yesbird.
Nice job on the breathing coral. Are you using an animation utility or scripting
something yourself? I'm using some 'old' cobbled script for replacing flagged
values between frames. I need to see if there's something more current.


I put a scene file together for you showing the use of negative blobs 'carving
out' smooth forms in positive strength blobs. Attached is a rendering from that
file. One drawback - there's a way to separately texture the voided space.  I'll
post the scene file in the binary scene file location.
Have a great night.

Hi, Mike.
Thanks, this is only a start, more serious work will follow. As to
animation, I am using very straight-forward techniques, described in
manual: https://wiki.povray.org/content/HowTo:Create_animations
and setting 'clock' variable for transformations.

I like how It works, at least now for trivial cases, may be in the
future I will need something more sophisticated.

“Give a man a fish and you feed him for a day; teach a man to fish and 
you feed him for a lifetime.” - Bible.

Many, many thanks for this example, last time you give me a fish, now
you are teaching me fishing ;). It looks like we thinking the same
: blobs are very powerful and flexible, but control is not easy and
intuitive, I spent about an hour setting parameters, trying to achieve
desired form, that I had in mind. And I started thinking about external
control, (like you do with point clouds) with CSG methods.

This is exactly what I need for manufacturing artifacts, will play with
them this night.

Happy rendering,

Interesting, I will be the first reader :)

And I even know what you are taking about (see attachment) :)

After Thomas will finish vase scene, I (or may be someone else) can 
animate it and this animation I can put on my POV-Ray Youtube channel.

This is about me - I didn't work with code for 3-4 month, but starting
from January can't stop. To give a rest to my mind I am switching to
something material, woodworking or ceramics:

I don't think this came from the Bible.  Do you have a citation?

I read it in Evangelia, don't remember chapter exactly.

Great, glad I can help. I'll try to contribute to your Roger Dean project when I
can. Always loved his work...Cool concept to model and animate.

Patrick Woodroffe was my illustration hero when I was in high school. I keep his
Mythopoeikon book beside me for inspiration. His early pencil and etching work
is very nice.

Here a link to some of my early sketches and 3D. I've only had the site up for a
few months so it's very much a work in progress ...like the rest of my life. :)
I started adding some of my resent POV work. I'm currently modeling bugs for
some rendering ideas.

I lost old website...now I'm using a free one. :)

This is what I found in a Web search.  Not even a mention of the Bible.

https://quoteinvestigator.com/2015/08/28/fish/

I ask for two reasons.  First, is that I find quotes mis-attributed so
frequently that I can never take them for granted.  Just reading that
article on just that one quote, you can see how people make up all kinds
of shit, often without realizing it.  Other search results mention
Matthew 4:19, only to say that people remember it wrong.

  "The human brain did not evolve to accurately represent the world
  around us; it evolved only to enhance the survival of our genes."
  --Victor S. Johnston

And it certainly did not evolve to remember quote attributions properly.

(But yes, I did verify the Victor Johnston quote!)

You can look up "Mandela effect" for more on this.

The second reason is that the source you are attributing is the
foundation of the world view of 1/3 of the world's population, yet few
of them seem to know what's in it beyond what their preachers tell them.
 Add to this our propensity to mis-attribute, and we have a real
problem, if a plurality of the world's population is to base their lives
on what's in that document, especially when their preachers have an
agenda.  While I don't tell people what they believe--I find that
unspeakably rude--I can and do challenge them on what is actually
written in their book.

I did decide to search the Bible for myself, and found 80 verses that
mention fish.  (Your translation may vary.)  None of them resembled this
quote.

Steven Anderson of the Faithful Word Baptist Church has a very interesting video
about why he's a KJV-only church, and why the other versions are less ...
reliable.
