# ZeroXR Model Explorer

> A 3D model viewer and inspector that runs in a browser tab, including the browser inside a
> Meta Quest or Android XR headset. No install, no account, and imported files are decoded on
> the device rather than uploaded.

## What it does

- Opens glTF, GLB and USDZ files. USDZ is decoded in the browser by a USD reader written for
  this app, so Apple's format opens on Windows, Android and Linux without converting it first.
- Enters WebXR from the same URL. On a Meta Quest or Android XR headset the page can open an
  immersive session and place the model in the room; on visionOS Safari it falls back to an
  immersive VR session. On a phone or desktop the identical scene renders inline in the page.
- Inspects rather than just previews: wireframe and UV views, X/Y/Z section planes, an exploded
  view that separates every mesh, animation playback, and a panel reporting triangle, material
  and texture counts and the bounding box.
- Imports your own files into on-device storage. They are not uploaded, and there is no account
  to create.
- Browses a catalogue of about 1,970 published models, each with its own page under /m/.

## How it differs from other browser 3D viewers

Most free browser viewers also decode locally and need no account. The uncommon part is the
headset: this is a URL, so viewing a model in VR does not require installing a Store app or
sideloading anything. Open the same link in the Quest browser and enter XR from the page.

## Limits worth stating

- Real-world scale is only as good as the source file. Roughly half the public catalogue was
  authored off-scale, so a size is shown on a model page only when it is believable.
- The assistant can search the catalogue and open models. It does not generate 3D models.
- Share links expire after 7 days. Catalogue pages under /m/ are permanent.
