I would say it depends on what the user wants.
Blindly converting from one format to another, the computer doesn't "know".

I mean, that's fine for default behaviour, however I'd provide the option to
center in either of the two ways I suggested.

So here we have a "part" of what if likely a bigger object / assembly.
It would make sense that it is positioned in relation to the other parts, and so
changing that deletes that very carefully specified position.

Having a coffee mug 100 units in the air and WAY off center doesn't make a lot
of sense.  We'd want to fix that obvious problem so that it doesn;t have to be
accounted for every time we instantiate the mesh, so it would get centered, with
y=0.

For other meshes, where having the center of the object at the origin would make
more sense from a rendering / modeling standpoint, then that would also be a
valid option.


But only the human user can look at that and know for sure.

Looks like WebGl1 is insufficient for Three.js and it wants WebGL2.
Did you tried it with Opera ?

I absolutely agree with all your statements, let's collect
user's opinions and then make decisions about further development.

The only question I have: how to inform the maximum number of 'povers'
about this service ?

Looks to be the same thing.
Tried enabling a thing in Brave to allow WebGL2, but that didn't work.

I'll give it a whirl in Edge since I already have the Win11 spyvirus on my
laptop.

Beg me pardon, but why not Chrome or Firefox ?

Looks good.
Got the teapot when the webpage loaded.
Took maybe 30 sec to convert the ghost.

(slick future feature would be to use a url, and convert from inside a zip.)

mesh.inc autosaved to my downloads folder.
object is called "model"
Not centered at origin
No inside_vector defined

After finding my object with min_extent, translating and rotating
it seems to work fine.

:)

Thank you, Sergei.

Thou hast no need for begging for anything, least of all a pardon.

I simply don't have those installed on any of my machines.

I do have "LibreWolf", but many sites don't like the signature of that.

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 ?
