Something I've always wondered about: All of these alliances for this and that format/standard/whatever - do they end up hiring some secretarial staff in some office for several decades? There should be several hundreds active corporate alliances now.

As far as I know: no. It’s people like you and me from the involved companies that are largely responsible for moving things forward (most often in addition to their regular engineering work!) through Working Groups (WG) or Task Sub-Committees (TSC).

Of course, but who's doing the actual admin work?

Who chases the sponsors for cash, who books the events, who collects the member fees, who creates that crappy member web site?

I'm just curious :)

This is a big deal. I used to work at Autodesk, trying to build software that made 3D blueprints available to everyone, everywhere. Rendering things on mobile is hard, in part because you need to writer bespoke renderers, and in part because the data formats for the assets are not aligned. Pixar developed USD, and it should really help to standardize 3D tech. In particular, I hope that USD can help make it easier to…

I don't know. You can stream Unity to mobile with the service I've authored (https://appmana.com/watch/theheretic for an example).

I see lots of off topic comments, but I'd like to ask as someone who played with fbx and similar formats supported by Autodesk and large parts of the gaming/CG industry what does OpenUSD provides exactly over different formats. I feel like there's never been a 3D counterpart to standards like Midi for audio.

Looks nice. However the issue with all 3d streaming I've ever tried is latency. It's great if you're near the server. Terrible if you're far away.

It's hard so say what the input latency is for the head demo you shared. I guess about 100ms, which is totally fine for a mostly static scene with simple orbit controls.

However I also tried out the Lebron James vs Father Time game. Input latency is over 1 second so it's not playable. Any time I touch the screen it freezes for a second then jumps to the new location.

Does anyone remember X3D[1] / VRML? X3D is roughly the same concept, 20-some years ago. Here's a hello world for X3D: https://www.web3d.org/x3d/content/examples/Basic/X3dSpecific... And here's a hello world for OpenUSD: https://www.openusd.org/release/tut_helloworld.html#viewing-... Although X3D is a bit more verbose, a lot of parallels can be drawn between the two, 20 years apart. [1] https://en.wikipedia.org/wiki/X…

I was tinkering in that space in the mid-90s, and always felt the file format was a missed opportunity, and wasn't taking any of the lessons of HTML. What I wanted (but never built) was a semantic file format, something like:

That's way too high level and ambiguous. Something could look okay in one browser and totally crap in another.

I remember VRML. Unfortunately KiCAD still uses it for 3D models (though thankfully it supports STEP files too)
