@donmccurdy @OpenDEM did you ever get https://github.com/OpenDEM/3D2PNG_GLB_Support to work?

@hnowlan who would be the right person to talk to about moving away from headless-gl and migrate to puppeteer considering that 3d2png runs on thumbor's image? Not sure if this is at all possible.

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

With node.js 18.4

Hi @dmaza – is this a new feature request for the 3D extension? Please provide a bit more context and we can triage appropriately.

Sorry I missed this, This is related to the work Commtech is doing to support GLTF on commons. I figured the 3D tag is appropriate but I did not mean to get your team involved.

Dear @dmaza @egardner @OpenDEM,

As you have figured out headless-gl route is a hits a dead end as it doesn´t support WEBGL2.

I have been working on it and created to projects exploring other two possible routes for a 3D headless render:

C++ / FIlament - https://github.com/gabriel-lucas/3d2png-C
Rust / WGPU - https://github.com/gabriel-lucas/3d2png-rust

They are not finished yet, they need more development.
The idea is to support all the GLTF standard extensions.
I have been testing them against the GLTF assets library - https://github.khronos.org/glTF-Assets/

I share them, so we could analyze possible routes for improving 3D image rendering.
There are some aspects to consider like: proper fit to mediawiki infrastructure, library dependencies, performance, security and so on.

Glad to discuss all with you

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

@GabrielLucas We are having internal discussions on how we can piggyback on Proton (see above) and move towards a Puppeteer + Chromium approach, but what you are working on looks very neat. You can track our progress at T424872: Evaluate shared Chromium service (WebSocket) for 3d2png and chromium-render. In the meantime, we will have a fallback thumbnail for GLB files.
