Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Authoring 3D & Spatial Apps with `<three-live>` and `<xr-live>`

`<three-live>` and `<xr-live>` compile declarative HTML and sandboxed Three.js scripts (`<script type="text/three">`) into WebGL2/WebXR on the web, Google Filament & Jetpack XR SceneCore on Android, and Apple RealityKit & Quick Look on iOS/visionOS.

## 1. Choose the Right Component & Bundle

- **Use `<three-live>` (`three-live.min.js` or `three-live-full.min.js`)** when you need:
    -   A 3D `.glb` / `.usdz` model viewer (`<model-viewer>` drop-in
        replacement) with built-in `EXT_meshopt_compression` decoding and
        `KHR_materials_variants` (`variant-name`)
    -   A procedural Three.js scene (including 2D `Shape`/`ExtrudeGeometry`,
        `THREE.CSG` Booleans, 3D `TextGeometry`, and `THREE.InstancedMesh` GPU
        instancing) with orbit controls and 1-tap mobile AR handoff (`ar`)
    -   PBR Next materials (clearcoat, transmission, dispersion, iridescence,
        sheen, volume), 5 filmic/commerce tone-mapping modes
        (`tone-mapping="neutral|aces|agx|reinhard|none"`), HDR emissive `bloom`,
        silhouette `outline`, `.hdr` environment lighting, ground contact

How to install

The exact contents, by fingerprint

mdr add google/three-live/three-live-authoring@sha256:bc8861860d5c070e

The line at the top of this page pins the label git:20261106.f814b45, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
