Hi,
New life form is born this night: spiral worm, implemented as
parameterized macro, code is here:
https://github.com/syanenko/Yes-World/blob/main/spiral_worm.pov
https://github.com/syanenko/Yes-World/blob/main/include/spiral_worm.inc

Now he is waiting for animation, which looks very promising :)

Thanks, it needs some polishing, parameters and control are non
intuitive ...

They are fascinating shapes and colors. Thanks for posting the code. I am
looking forward to going through it, to learn some new things.

Thank you, Kenneth, I'm not sure, that you will find something new,
having your POV experience :). Code is raw and needs some refactoring,
please ask me questions, if you have them.

But if you like worms, you may also look at this demo, I'm planing to
combine them:

I discovered something new today...about Github. I am a 'newbie' when it comes
to downloading an in-line scene file there. (Github adds line numbers preceding
each line of code, which would be a problem when simply copying it to run in
POV-ray.) But by hitting the 'raw' button there, the code comes up as a nice
clean text file ready for downloading. Easy!

Looking at your code, I see that your #declared variables are all written with
lower-case letters. I would suggest that you write them with at least the first
letter capitalized, because it is certainly possible that you could pick a
variable name that conflicts with one of POV-ray's many built-in keywords (which
are all(?) written in lower-case.)

Personally, I now write most of my variables with all caps, like TEXTURE or
whatever. Others here have different schemes, like preceding the name with a
line segment--     _texture

(Actually, I would write it as MY_TEXTURE or something similar.)

We each have our own way of preventing the name-collision problem.

IMHO, if you don't want to clone repository, but want just to play with
code, the better way is to download zipped version (see attachment) -
this way you will not miss any dependencies, like include files, for
example. But cloning has following advantage - you can always see diff
to original after your experiments and easily can revert to it.

I suggest 'GitHub Desktop' with friendly UI:
https://desktop.github.com/

It's true. Although I'm working under windows now, because sticking to
to ZBrush and C4D in my graphics projects, natively I'm a unix-man,
prefer unix-style and classical 'C' notation, all with small letters and
'_', writing CONSTANTS in capitals, to avoid conflict with reserved
words, I'm using the leading '_'.

The only alternative, I like, is unicode, like it's possible
in Julia language, for example:
https://docs.julialang.org/en/v1/manual/unicode-input/

Btw, this is very perspective and well-thinked language, opposite to
Python, and even has a package with POV support (!):

Sure, but sometimes style-guides can help in team-working, especially in
a big projects.

Hmm. The two Github pages that you linked to do not have the form or layout as
seen in your attachment. Is your screenshot taken from the 'Github Desktop' app?

Yes, I saw that; I might even download it! It would help me to understand Github
better. (As you can tell, I know almost nothing about it or how to post anything
there.)

Yes, I see the advantages of that. (I have never worked on 'team coding
projects' myself.)

No, this is an original GitHub web UI - just select repository name at
the upper left corner ('Yes-World'), and you will see this form.

With 'GitHub Desktop' it is as easy as browsing with Chrome :), please
fill free to ask me questions, if you will choose 'github way'.
