Been digging around in Augmented Reality(AR) for a while.
Successfully been able to convert obj to USDZ with Xcode on Mac using xcrun usdz_converter in terminal.
What I’m curious about can:
Have seen vectary and clara.io converting to USDZ
Also saw the post on Three.js issues: https://github.com/mrdoob/three.js/issues/14219
Thanks for the help!
There’s a new usdzconvert utility that (I think?) can convert glTF and some other formats to USDZ without XCode – see https://twitter.com/deniskovacs/status/1138458261437501445. I haven’t tried this myself though.
Do you know of another way this could be done?
Nope. 
Looking into your recommendation still requires in the pipeline Xcode but then again I’m on a mac maybe need to test this with Linux, at least when I tried to install the pycode. Then ran into having to install PySlide, requires a certain configuration to do this process. Will keep attempting, still learning!
Getting warmer, things are beginning to take shape, found the right readme file:
After many failed attempts with pip and pip3, during the build I keep running into an import Image error. Read through stackoverflow related problems. It is something with either my environment or I need to hear from others they have gotten this python script working where we can discuss what went wrong. Possible revisit, for now Xcode is a viable solution!
