model-viewer: web component for displaying 3D models, with editor and fidelity tools

What it supplies: This is the main repository for the <model-viewer> web component and related projects: a post-processing effects plugin, the documentation site, render-fidelity testing tools, shared 3D models and environment maps, and the space-opera editor for the component. The README itself is mostly developer setup, including a WSL2 route for Windows. Useful for: - Show glTF 3D models on a web page with a single HTML element. - Edit viewer settings with the space-opera editor. - Test how faithfully a viewer renders models using the render-fidelity tools. First action: - Read the <model-viewer> project README and modelviewer.dev for usage. - For development, install git, Node.js and npm, then git clone --depth=1 the repository and run npm install. - Use npm run build, npm run serve and npm run test. Prerequisites and limits: Needs git, Node.js and npm. The README recommends cloning with --depth=1 to avoid about 3 GB of history, and advises Windows 10 users to develop inside WSL2 with Node installed via NVM, cloning over HTTPS from inside WSL and setting CHROME_BIN for tests. Fidelity tests need GUI support, available in WSL only on Windows 11. - This README is about repository development, and usage instructions are in the component's own README and website. - Windows development has known dependency and line-ending issues. - Fidelity tests may fail under WSL on Windows 10. This README does not state a licence in the text read here, so check the repository's licence file. Models you display and the shared assets carry their own licences. Written from the README text only. Statements are as the README gives them; nothing was installed or run.
