Hi,
please have a look to the attached image.
I try to create a snake-alike chain of these tiny bodies, but I fail to
get them to look the way I need them to look. Ideally, each small body
is attached to each other, and the chain they create has some gentle
curves in it: a gentle bend upwards, and tiny bends towards the left and
right sides. But i fail. Heck, sometimes I even get many bodies that are
not connected at all!
Who has an idea how to implement an algorithm that is giving better results?

Instead of the above, I think you should use a radius and rotation by an
angle.
#declare MyAngle = rand(MyRandomer)*2*pi;
#declare MyX = MyX+MyRadius*cos(MyAngle);
#declare MyY = MyY+MyRadius*sin(MyAngle);
#declare MyZ = MyZ;
Or something similar.

Thanks. I want to give a try. But for now, "MyRadius" causes problems
because it has nowhere initialized. With what value do you initialize it?

Something like this:
#declare MyRadius = 4;
Change it to whatever size you need.

Thanks again!
I was rendering the scene, but the result is still not good - often, the
individual bodies are not touching each other.
See the attached image, that is what I try to achieve. It is a very,
very ancient life form, that lived long before the Cambrium in our oceans.

If you need your nice little "cells" touching each other, why not using
equidistant splines?
I made a quick example (source is in pbs-f).
Original code is from ABX - Place and orient objects along spline -
http://news.povray.org/povray.general/message/%3Cttoenucoq6fcgkun57la24s9ia4ij5o573%404ax.com%3E/#%3Cttoenucoq6fcgkun57
la24s9ia4ij5o573%404ax.com%3E
..
Of course you would have to generate some semirandom splines...

Man-oh-man, that looks quite cool! Yes, this is getting close to what I
need!
I need them to touch each other, but I guess, this can be done by
altering your code a little bit. I also need them to curve a tiny bit
towards both side, but that, too, can surely done by tweaking your code.
That life form, by the way, is called Orbisiana.

Actually, what you see in the image is a colony of Orbisiana.
An individual Orbisiana has a barrel like shape.

Those are very old life forms, almost proto-life, from before the
cellular nuclei appeared. I also think they mostly did not contain any
DNA nor RNA.

Thanks for that. Making such multi-object equidistant spline shapes was never
easy for me; I did manage to do it once-- with much work-- for a long-ago scene.
But I lost it years ago :-(

Here is my new problem, and it has nothing to do with POV-Ray: the BLACK
SCREEN.
I am using an Intel i3 processor, and the Intel HD Graphics driver. That
combination is known to cause the Black Screen during graphical works.
In my case, i tried to do a simple animation with the modified scene,
but get always the Black Screen after rendering the 4th or 5th frame. I
don't think, that there is any solution to this, for my computer.
I have to ask anyone of you, if you could render 100 frames for me, if
you can forgive me that request.

No problem,
I do it for you. But where can I upload the results?

Hmmm, best to send it by e-mail. Saved inside a ZIP or RAR file.

Okay, I was reading through the source code of this scene. This
"Spline_Trans" is new to me.
Is there any way to change the spline shape itself by random factors? At
the moment, it is like an "M", but I don't mind variations between "U"
and "M".
Each of these chains resembles a colony of Orbisiana, but based on the
water current, each chain had different angles.
I tried with changing the SEED, but all that does is to shorten or
stretch that given "M" shape. And when stretched, there are even wide
distances between each body.
One update: I made this change to the scene:
#local Length = Length+vlength (Point-(Last*1.0003));
Before it was:
#local Length = Length+vlength (Point-Last);
