`<model-viewer>` is a web component that makes rendering interactive 3D
models - optionally in AR - easy to do, on as many browsers and devices as possible.
`<model-viewer>` strives to give you great defaults for rendering quality and
performance.

As new standards and APIs become available `<model-viewer>` will be improved
to take advantage of them. If possible, fallbacks and polyfills will be
supported to provide a seamless development experience.

## Installing

### NPM

The `<model-viewer>` web component can be installed from [NPM](https://npmjs.org):

```sh
# install peer dependency ThreeJS
npm install three 
# install package
npm install @google/model-viewer
```

Finally, include the `<model-viewer>` script in your project.

```js
import '@google/model-viewer';
```

### CDN

It can also be used directly from various free CDNs such as [jsDelivr](https://www.jsdelivr.com/package/npm/@google/model-viewer) and Google's own [hosted libraries](https://developers.google.com/speed/libraries#model-viewer):

```html
<script type="module" src="https://ajax.googleapis.com/ajax/libs/model-viewer/4.0.0/model-viewer.min.js"></script>
```

For more detailed usage documentation and live examples, please visit our docs
at [modelviewer.dev](https://modelviewer.dev)!

### Important note about versions
Our goal for `<model-viewer>` is to be a consistent, stable part of your web
platform while continuing to deliver cutting-edge features. We’ll always try
to minimize breaking changes, and to keep the component backwards compatible.
See our [guide to contributing](../../CONTRIBUTING.md#Stability) for more
information on backwards compatibility.

For your production site you may want the extra stability that comes by
pinning to a specific version, and upgrading on your own schedule (after
testing).

If you’ve installed via [NPM](https://www.npmjs.com/package/@google/model-viewer), you’re all set - you’ll only
upgrade when you run [`npm update`](https://docs.npmjs.com/cli/update.html).
Note that three.js is a peer dependency, so that must also be installed, but can
be shared with other bundled code. Note that `<model-viewer>` requires the
version of three.js we test on to maintain quality, due to frequent upstream
breaking changes. We strongly recommend you keep your three.js version locked to
`<model-viewer>`'s. If you must use a different version, npm will give you an
error which you can work around using their `--legacy-peer-deps` option, which
will allow you to go outside of our version range. Please do not file issues if
you use this option. 

## Browser Support

`<model-viewer>` is supported on the last 2 major versions of all evergreen
desktop and mobile browsers.

`<model-viewer>` builds upon standard web platform APIs so that the performance,
capabilities and compatibility of the library get better as the web evolves.

## Development

To get started, follow the instructions in [the main README.md file](../../README.md).

The following commands are available when developing `<model-viewer>`:

Command                         | Description
------------------------------- | -----------
`npm run build`                 | Builds all `<model-viewer>` distributable files
`npm run build:dev`             | Builds a subset of distributable files (faster than `npm run build`)
`npm run test`                  | Run `<model-viewer>` unit tests
`npm run clean`                 | Deletes all build artifacts
`npm run dev`                   | Starts `tsc` and `rollup` in "watch" mode, causing artifacts to automatically rebuild upon incremental changes
