The standard THREE.js 3MF loader cannot be used in a Web Worker, as it uses DOMParser.
This tiny fork includes the normal loader code and patches it with the xmldom and query-selector packages, as suggested in this GitHub comment.
This makes the loader usable in a Web Worker.
npm install https://github.com/manyfold3d/threejs-webworker-3mf-loader
or
yarn add https://github.com/manyfold3d/threejs-webworker-3mf-loader
import { ThreeMFLoader } from 'threejs-webworker-3mf-loader'
loader = new ThreeMFLoader()
model = loader.load(path)
This code will be updated occasionally with the 3MF loader code from upstream THREE.js, but I can't guarantee I'll notice. Feel free to open issues to remind me if it changes.
All credit goes to the three.js authors for all their work, and @coder-free and @morrisallison for their suggestions in various GitHub comments, which I've just wrapped up into this package.
