YES! I am glad that finally you win.
But 30 sec is toooo looong for such small model, I am getting result in
2-3 sec, but there is ocean between us :).
Possible solution: I can open github repository and you will be able to
install this service on more accessible server.

You are always welcome, now I am start thinking about spline
editor for POV-Ray, based on this example:

Yes, I am certain that such a thing would be useful.

a while back,
and there was the PointWriter project
And someone had a spline workshop, IIRC.
Tor Olav Kristensen (TOK) has a lot of spline stuff on github
Jerome Grimbert (Le Forgeron) has his hgpov38 project that uses a wide variety
of splines
And I made a big list for jr of all the different spline types
So there's certainly a lot of things that could keep you busy ;)

Many thanks for this info, I will get back to splines after converter
polishing. Btw, would you suggest the best way to inform the community
about its existence ?

Of course.
It's always nice to have a sort of head-start, with some keywords and even code
to get things moving quickly.

What I would greatly suggest is that you not just leave it as a converter, but
add some small embellishments to make it a valuable learning tool.
It ought to be easy enough to make a small mesh and show how the normals are
calculated, how vector cross products allow the order of the vertices to
determine the direction of the normal, etc.
[X] Create an explanatory diagram as an .inc file
Then you can not only advertise it here on the forum, and elsewhere, but also
slip references to it in discussions on stackexchnge, stackoverflow, Wolfram,
and other places. Make sure you have a didactic, academic graphic that will
attract computer science / graphics / gaming students to visit your app if they
come across it in a web search. That way it has a lasting value completely
aside from JustAnotherFileConverter.
Make sure you put some prominent references to POV-Ray and the newsgroups in
your graphic. (I'd also suggest putting some standard POV-Ray header info in the
inc file, along with a reference to you & your web converter URL)
That way, if people find your project to be a useful learning tool in addition
to it being just a converter, they may be encouraged to try POV-Ray, and get
involved with many of the projects - including the ones you are working on, or
don't have time to work on. And I have no problem with using 3js as the basis
for a new version of POV-Ray, so any CG tools developed in 3js are valuable as
well. (You know I draw my knowledge and inspirations from a wide range of
platforms and sources)
So - that's always where my mind is going when we talk about any project. "How
do we attract people and bring them together to (re)build a thriving computer
graphics community"

Bill, thank you very much for this bundle of ideas, I will think about
them and follow your suggestions.

Exactly, good luck with it. :)

It is completed now: I implemented a progress bar and added two
additional metal materials for preview.

This looks awesome !!!
But I get " 504 Gateway Timeout " from behind my corporate proxy.(for all of
your site by the way).
So trying on my phone, I get a display smaller than my screen. but appearing
functional.

I think you should look at GIS packages (QGis/OpenSceneGraph...), and the way
geometries are coupled with a text based projection file... recording
coordinates, centering for treating and reapplying on exit. or leaving separate
file from option?

Thanks - this is an interesting idea, taking in account that I have
experience working with QGis and like it very much.
There is always a space for improvement :)

I didn't think about mobile platforms, working on design, so some
distortions are possible, but maybe this is better than nothing.)
At present the assumed resolution is HD 1920x1080, but I will try to
improve it.
