A storm is approaching.
Still working this out, but the key concepts are in place.
I could probably use a helpful quick-start pointer or two in using ffmpeg.
(but DAMN it is FAST! :O )
60 frames at 15 fps rendered in qtpov on Linux Mint 18.3
ffmpeg -y -r 15 -i SpiralWarp%02d.png -crf 15 -c:v libx264 -pix_fmt yuv420p

looked good in konqeror

That is slick!

Uh, that command below looks fine. What else did you want to do?

Faster than real time.

That is really cool, a great starting point for some interesting animated
effects. I'm following this with great interest (thinking about what the
addition of *more* spirals/vortices would look like as they all interact-- and
with some warp{turbulence...} thrown into the mix.)
As-is, it looks like the effect is 'confined' to a square; it would be great to
see it confined to a circle instead (if possible)-- to be more like a storm.

Was the work on spiral warp ever completed? Is it implemented in POV 3.8?

I worked it all out to my satisfaction at the time:

It hasn't been implemented anywhere else AFAIK.

Can you link to the code itself? Have you written a tutorial? Thanks.

I mean there's what I posted, which includes the fundamental functions to
perturb a pigment pattern.
I haven't posted the source for the twisted spheres image - since that was long,
involved, and a skull-cracker.
I juggled a lot of big projects in a explosion of sustained activity, and then
with all that's been happening IRL, I just hit burnout, and needed to focus on
local things here for a while - so no tutorial.
I'm assuming you want to use it to make storms in your media?
The basic code to add a localized vortex to a pigment pattern is here:
http://news.povray.org/povray.binaries.images/message/%3Cweb.5d2a0c323717ac604eec112d0%40news.povray.org%3E/#%3Cweb.5d2
a0c323717ac604eec112d0%40news.povray.org%3E
Try that in a simple test scene and see if that works.

Wow! That would be perfect for my gas giants, such as Sagan/Whatmough or
Qais/Ghurghusht!
Which unofficial patch did you use?
See you in Khyberspace!

When I get some rest and have some more energy and focus, I'm going to try to
make sure it's fully applicable for use with 3D pigment patterns and media.
I figured out how to implement a placement / repetition warp in SDL, and so once
it's all worked out, you should be able to plop multiple spiral warps into a
single pigment pattern definition, and have them all work.
It's gonna be a little complicated, so it may take some time, but the important
parts are figured out - so now it's just making a scene incorporating all of the
pieces, seeing what's broken or missing, and iteratively tweaking it...
No unofficial patch - it was all done in standard POV-Ray 3.8 (qtpovray)
