If you want to convert a .gltf file to an .usdz file you need a quite complex setup. This repository aims to simplify the whole conversion process by using a docker container.
We use the usd_from_gltf repository from Google google/usd_from_gltf in conjunction with the USD repository from PixarAnimationStudios PixarAnimationStudios/USD.
Since USD takes a long time to build, it has its own docker image (see \usd). You can find it on Docker Hub. https://hub.docker.com/r/smthfor/usdz
The usd_from_gltf tool can be found in gltf-to-usdz and is online at https://hub.docker.com/r/smthfor/gltf-to-usdz
There is also a version build with node installed, can be found in gltf-to-usdz-node and is online at https://hub.docker.com/r/smthfor/gltf-to-usdz-node
Run the docker command:
docker run -it --rm -v $PWD:/usr/app smthfor/gltf-to-usdz:latest inputfile.glb outputfile.usdz
