@Amdrel @mikez-WMF Is there any way I can help out here to move the project forward?

We can track this in a follow-up ticket perhaps. I left it out for now because it introduces a design dependency if you want users to be able to play/pause/select specific animations. I did see that it was present in your implementation.

Thank you very much for your work @Amdrel!
I have successfully tested the following Khronos Examples(https://github.com/KhronosGroup/glTF-Sample-Models/tree/main/2.0):

Great work @Amdrel. I've successfully tested the thumbnailer with a few .stl files, as well as Duck.glb, Avocado.glb, and coffeemat.glb with KTX compression.

I'm glad to hear that. If you need any help, feel free to reach out. You might also want to join our 3D Wikimedia Telegram channel: https://t.me/+tMgoJxx8D7I5NTQ8

A while back, I contacted https://www.glb2png.com (commercial GLB thumbnailer) to ask about their system architecture:

As far as I can tell, puppetter.js is already part of the MediaWiki infrastructure: https://www.mediawiki.org/wiki/Proton
I see the advantages in its independence from data formats and viewers. We’ve already listed the pros and cons here: https://commons.wikimedia.org/wiki/Commons:Textured_3D

With node.js 18.4

No, this ist just working for some very Limited cases. WE should move away From headless-gl!

I made a successful test on base of node 18.20.8. Is now node 20 required?

Hi @Carsten_Steger, Unfortunately, I'm not a three.js expert, but @donmccurdy is. I hope he can answer your questions.

Does this also work with external thumbnailers such as 3d2png?

As far as testing the changes, unfortunately the only way is to install a local copy of mediawiki and the 3D extension with it's dependencies.

@dmaza Very gladly

I agree. My goal is to follow up with updating to threejs 162, and then see what can be done to move GLB support forward.

@dmaza The patch was released over a year ago, so there are bound to be more security vulnerabilities now.

The problem is that the standard lighting system from Three.js is not used here. This differs greatly from previous versions and does not look quite as good for STL files. You can test this here: https://opendem.github.io/WikiMediaExtension3D_Test_GLB_Format/ The adjustments made by the WMF have now resulted in some models no longer displaying at all.

@Carsten_Steger You could use this viewer for testing: https://github.com/OpenDEM/WikiMediaExtension3D_Test_GLB_Format

An interesting project on the topic of 3D: https://commons.wikimedia.org/wiki/Commons:UK_Heritage_3D_Data_at_Risk

@Sj Good idea, I think this would be the place to collect it: https://commons.wikimedia.org/wiki/Commons:Textured_3D

We now have a demonstration wiki for textured 3D models: https://mediawiki3d.org/
Feel free to add content.

Gabriel Lucas gave a presentation on “3D content” at Wikimania, which is available on YouTube: https://www.youtube.com/watch?v=lE5swmpnTGA&t=5653s.

Thanks a lot Brooke. If I can support here, please let me know.

Since T367677 has now been closed, it would make sense to continue with this patch here. Could someone please get @bvibber into this task? She has implemented T367677.

Thanks a lot @bvibber!

Here is the link for the telegramm group: https://t.me/+tMgoJxx8D7I5NTQ8

• note that community wishlist is a good opportunity to look for getting additional development resources like dev contractor time to help push these things towards production!

@bvibber Thanks!

That is not a problem. There will only be differences in the display. The new realistic lighting system no longer looks as arty as before.

I send you an email at 11:59, and now again. If the mail has not arrived please let me know.

Hi @Sressler, Nice to have you with us. We are documenting the current status of the work here: https://commons.wikimedia.org/wiki/Commons:Textured_3D
There is also a Telegram Group.
There will also be a video conference on Sunday 23.02.2025 at 16:00 UTC.

Hi @ALoopingIcon, if you would like to contribute something to the development system, please write to me for the access data: contact@opendemdata.info

Sorry, you're absolutely right, it's 23 February 2025 and we'll be meeting via Jitsi.

Hi, as we have some options on how to proceed with WikiMedia 3D we would
like to invite you to a video conference. You can find the proposal for
the Agenda here: Commons:Textured_3D.
Feel free to edit and add to it. Date would be Sunday 23.02.2025 at 16:00 UTC.
Get in contact for the dial-in link for Jitsi (contact@opendemdata.info) or join the Telegram Group.

That sounds very good. I have just commited a patch for 3D2PNG: https://gerrit.wikimedia.org/r/c/3d2png/+/1114772

The 3D extension will be updated next week. In order to remain consistent, it would be good to install this patch as soon as possible. For my comments regarding RoomEnvironment see above. The code was only commented out, maybe it runs on the target system. Please test.

Thank you. I hope this fits now.

If I can do something here please let me know.

Unfortunately I could not get the RoomEnvironment patch to work on other systems. I have created a version that tries to simulate RoomEnvironment with a classic lighting system: https://github.com/OpenDEM/3d2png
The differences are illustrated in the Readme.md using images.

Thanks @TheDJ!

@Esanders: Are there still points that prevent a merge?

No, I am not familiar with the MediaWiki security concept.

First attempt via magic number:
https://github.com/OpenDEM/MediaWiki_Extension_3D_GLB/tree/main/mediawiki_config_files

It would be great if you could vote here:
https://commons.wikimedia.org/wiki/Commons:Requests_for_comment/Technical_needs_survey/Support_textured_meshes_on_Commons

As the changes have had no visible effect, the standard lighting system is to be retained. Even if this no longer looks as aesthetically pleasing as it used to in some cases. The new lighting system was introduced with three.js r155.

Have a look at the status of work here: https://commons.wikimedia.org/wiki/Commons:Textured_3D

I have added the current status of the ongoing work to the page https://commons.wikimedia.org/wiki/Commons:Textured_3D. Help is very welcome.

Yes, I have created a prototype here with the suggested changes: https://opendem.github.io/WikiMediaExtension3D_Test_GLB_Format/stl_shadow.html
But I can't see any difference to before.
I'm also working on a patch for 3d2png (T345953) and realised that the RoomEnvironment lighting system used here doesn't work headless. Therefore, I would like to wait for feedback here.

I am waiting for feedback from @donmccurdy. But I think we should stick with the new standard lighting system, even if it doesn't look quite as aesthetically pleasing in some cases.

I have now got 3D2PNG running with three.js 162: https://github.com/OpenDEM/3D2PNG_GLB_Support.
The lights need to be revised, because RoomEnvironment is not working with headless rendering.
The high risk vulnerabilities could be reduced, but still 3 are left.
We are continuing to work on it.

Unfortunately, after the update to node.js 18 I have many error messages and cannot get the code to work. I am surprised that this works in production.

Hi @Jdforrester-WMF, did you get the code to work with node.js 18?

It's done, I've found it: https://de.m.wikipedia.org/wiki/Datei:Asad_Al-Lat.stl

@Esanders : Can you please send me the URL of the STL file?

@Esanders can you please add @donmccurdy to this task? He did the lightning system.

As of today, it is possible to vote on ‘Technische_Wünsche_2024’ for a thematic focus (26.11.2024-9.12.2024). Please vote for 'COMMONS-ERSTELLEN' to bring our cause forward!
https://de.wikipedia.org/wiki/Wikipedia:Umfragen/Technische_W%C3%BCnsche_2024

I have now got this working based on three.js 162, and Donmccurdy has made the light shine again.
Some adjustments had to be made and I will try to apply a patch today.

Sorry, the links got lost:

Event:Commons community discussion - 21 November 2024 8:00 UTC

The Wikimedia Foundation will be hosting a series of community calls to help prioritize support efforts from Wikimedia Foundation for the 2025-2026 Fiscal Year.

It has now worked on the third attempt: https://meta.wikimedia.org/wiki/Community_Wishlist/Wishes/Support_full_colour_3D_models_on_Wikimedia_projects

Back on the wish lists:

1. Technische Wünsche (the German original): https://de.wikipedia.org/wiki/Wikipedia:Technische_W%C3%BCnsche/Wunschparkplatz#Unterst%C3%BCtzung_texturierter_3D_Modelle
2. Community Wishlist: https://meta.wikimedia.org/wiki/Community_Wishlist - Not visible yet.

The current issues surrounding Sketchfab show how important a non-commercial platform for sharing and visualising textured 3D models would be. Click here for the petition with lots of background information: https://www.change.org/p/keep-sketchfab-alive-preserve-open-access-to-3d-art-museum-collections

Thanks a lot @GabrielLucas for your enlightening background information and all the work! I will approach our local Wikipedia chapter next week and ask for support for the Wishlist.

I have created a prototype for a viewer that also supports GLB files in the ‘mediawiki’ style. Only simple GLB files and KTX2 compression are supported. I am not yet satisfied with the positioning of the models, especially in view of the thumbnails. Help and feedback are very welcome.

Hi @bvibber, are you currently working on the extension? Otherwise I would give it a try. It would be great if you could take a look at my comment on 1026883.
