No, the file is OK, you can check this yourself here:
https://threejs.org/editor/
The project in beta state now, so some issues are possible,
will fix it soon. Many thanks for testing and bug reports -
I am really need them.

Interesting, I guess yes, will try it little bit later.
Right now I am working on POV-Ray materials support.

Good idea, saved it to my TODO list.
Wishing well.

Yes, I know, but I did not see any online GUI anywhere.
I am thinking about something like this, but implementation could be
tricky. As far as I know, Blender supports POV-Ray and has a GUI, but I
don't know details, preferring C4D.

Btw, last year I did this experimental project for server-side
rendering: https://povlab.yesbird.online/
Maybe it was the first step toward what you are dreaming about ?

Yes, "something" like that.
But instead the code-block many sliders and checkboxes and select-boxes.
And only one or two object (box and sphere) to show the texture.
And a download-button to get the texture.
This treejs looks indeed very promising, maybe I'll give it a try for my own
website.
Your all2mesh-tool:
If you could extract the textures also, I would bring the Mars-Rover or
Ingenuity to life.
The tool is nice, maybe I can use it sometimes, especially for some NASA-Stuff.

Don't you mixing a texture and material ?
http://www.povray.org/documentation/view/3.60/324/
http://www.povray.org/documentation/view/3.6.1/331/
In any case implementation will not be difficult - I guess, you can try
it yourself. You will only need to install node.js and master
javascript, also PHP alittle.

Yes, it's really cool. Almost standard-de-facto for WegGL/WebGPU works
now.

Now it's "POV-Ray studio" :).

Maybe later, after finishing two active projects.

Use search, Luke !

Just for kicks, I searched Thingiverse for Povray . . .

Chess set I designed in 2001, originally in PovRay.
Recently used Openscad to create the STL file.

Chainmaker is rather interesting ...
Btw, Bill, I need your advice. I am working on online viewer of math
objects (screenshot attached):
https://mathview.yesbird.online/
and now it has export only to OBJ.
Is it worth adding a POV exporter to it, taking in account that POV-Ray
already has a powerful library for generating math surfaces ?
Remembering quote by Steve Jobs: "Deciding what not to do is as
important as deciding what to do" ? :)

Well,
All I can say is that although we have things like parametric, isosurface, and
polynomial - what we don't have is a visual modeler for such things.
There does exist MathMod - which can be quite cryptic, and Desmos - which can
help visualize equations. But neither have any sort of export feature.
I'm a fan of the mathematical objects - it's probably one of my favorite things
to play with and render - but after over a dozen years of experience, I'd say
that there are usually only a few select shapes that have real, broad utility.
sphere, cylinder, torus, Dupin cyclide, etc.
Now, on the other end of the spectrum, when you need a specialized shape, and it
has to have very exacting dimensions and attributes, then parametrics and
implicit isosurfaces are probably the only things that will fit the bill -
especially when combined with surface displacement.
And those things can be VERY difficult to visualize.
I really like what you're doing, and there are things that I would want, and
would be great to experiment with. But I don't know what sort of workload is
necessary to make them happen, or what other projects you have to wrap up.
So, ultimately, I'd say that you're going to have to decide for yourself.
We can discuss this more, but I'll leave you with all of that to think about.
