USDZExporter animations

[positlabs]

Is your feature request related to a problem? Please describe.

I'm building a dynamic scene in ThreeJS, and I need a fallback for webXR (AR, specifically), for devices that don't support it. One solution is to use Apple's Quick Look app, but it requires USDZ format. I'm using the USDZExporter to export the file, but it loses the keyframe animations.

Describe the solution you'd like I'd like the USDZExporter to pull the animation clip from my loaded model.

Here are some useful links for the USD animation schema: https://graphics.pixar.com/usd/release/tut_xforms.html https://developer.apple.com/documentation/arkit/usdz_schemas_for_ar/autoplay

Describe alternatives you've considered

I could build some kind of cloud function docker thing that converts from GLTF to USD since the GLTFExporter supports animations. It's not an ideal solution.

Anyone interested in co-developing animation support for USDZExporter? I may be willing to do some dev work.

We've got a first implementation of this and are going to make a PR soon –
see https://twitter.com/hybridherbst/status/1563676038214959104. Some cleanup to do first, it's a pretty big refactor.

Is there source code for this? If so, where? If not, ETA?
