Seen Autodesk here, which might - or might not - mean that the standard is also applicable for 3D engineering artifacts. However I see no explicit mention of this in the article by the link. Can this standard be well used for, say, designing a model for a 3D printer?

I suspect, but have no evidence, that it's the Maya side of AutoDesk

I doubt it - for 3D CAD there are STEP/IGES etc. Most of the 3D printing issues are from triangulation/voxelization of analytical surfaces rather than interchange format.

Can someone ELI5 how this is different from glTF? What information does the OpenUSD format carry?

USD is at a higher level of abstraction than gltf (IMO). It was created to ease things such as scene graph LOD (levels of detail) for example. It's made for very large scenes. It was created as a file format to exchange very large scenes for 3d animated movies. Inside of a USD file you can point to many other files, for example GLTF, OBJ files etc.

It seems like a great format so far, but I'm skeptical based on Adobe, Apple, Autodesk track records for "open" formats.

I look forward to USD & USDZ being supported more consistently. The same file can look quite different even within the Apple ecosystem, as these screenshots from a few monthes ago show: https://twitter.com/mrdoob/status/1654494500230778887

Something is broken with your texcoords. The whole texture atlas is misaligned.

For professional CAD/CAM use cases? No. Those do not use meshes but more sophisticated and computationally expensive 3D modelling techniques. For hobby use? Sure. Most of that stuff uses meshes already.

Edit: it’s actually not just meshes that are supported. But the usual CAD/CAM surfaces are still not supported.

Stub for arguing about what "USD" means. These comments were originally at the top level but the offtopicness was choking the thread so I'm moving them here. I left https://news.ycombinator.com/item?id=36962294 out because it has actual interesting information about the project.

I am so glad that they picked an acronym so obvious so as to not confuse anyone.

Can someone clarify what the conversion ratio between OpenUSD and OpenEUR will be though?

Earlier quoted context omitted.

OpenUSD sounds like something bitcoin-related. The USD acronym is so known for being for US Dollars, why would they want to overload it...

I also thought this was crypto related and felt it was odd Adobe, Pixar, and Autodesk were involved.

Yeah at first I thought it was some kind of store payment crypto they were introducing.
