Hi to all,

While exploring the world of 2D and 3D attractors - exploration NOT yet finished
but I rendered quite a bunch - I had the idea to look for something that makes
2D attractors still more attractive. I thought about using a density map but
what I found was far beyond my skills - at least for now.

Well, to put it in a nutshell:
I remembered Ilya Razmanov's 'Img2mesh' converter.
Installed Python 3.14 and gathered the necessary Img2mesh files and after using
some Gaussian blur on my attractor image (see original img resized to 800x600 on
the left, 200k spheres) I fed it to 'Img2mesh'.

A 'quick and dirty' job! I didn't pay attention to the size of my original POV
image (1600x1200 px) but 'Img2mesh' ate it and spat out a 144 Mb POV file in no
more than 2 minutes.

I did not expect too much - I used the output file as is - and, wonders never
cease - after 49 minutes I got a result that almost knocked me off the rocker
(see img resized to 800x600 on the right).

Ilya, great job and I will dive into your 'Slimy Mudhole'!

Cheers
Droj

Good start ;)

I think you're familiar with them, but there are these two pages on 
attractors that are really interesting:

-> <https://paulbourke.net/fractals/clifford/>

Yes, they are really attractive ).

Not long ago I started to play with them too and found this page:

There are also "computer graphics" attractors.

More of a modulated procedural pattern.

They are used in packages like Grasshopper, Maya, etc.

I've played around a bit with things like this before I even knew they had a
name.

I know that Mike Williams, Tek, and others have done similar things, and it's
really interesting once you couple the concept with not only modulating size -
but any attribute.

Size
Shape
Color
alpha
finish
ior

.....

You can also use the attractor values as the input for an interpolation.
So you can do cool things like use SDFs or isosurfaces or any other kind of
function, and mix various functions as you move around on a surface.
