"If USD creates a library that can eliminate this work for the user, it will go a long way to ... allow use of USD in browser based applications,""
Exactly in the same way Jpeg was successful: it came with it's open source lib, probably still used today.
But I don't get it why people are making the comparison with HTML since:
- given the mess many web sites were in, vs. W3C HTML specs (thanks, MS and IE !), the comparison just shoots its own foot
- the metaverse is mostly about VR, right ? Soooo, you don't come to even see/use a browser !
So far, if any 3D modelling language comes up as supported by many tools (drawing, gaming engines, etc ...), this may indeed come as a real thing.
If, at contrario, it ends up in a format war, ala HTML, Betamax/VHS etc, not much will really happen.
