# Add a 3D model with threebox
This example uses a [custom style layer](https://docs.mapbox.com/mapbox-gl-js/ja/api/properties/#customlayerinterface) with the [threebox](https://github.com/jscastro76/threebox) plugin to add a 3D model to the map. Threebox abstracts the 3D rendering library [three.js](https://threejs.org), and keeps its scene camera in sync with the Mapbox GL JS camera.
An alternative example that uses three.js directly to display a 3D model is available at [Add a 3D model](https://docs.mapbox.com/mapbox-gl-js/ja/example/add-3d-model/).

**JavaScript**

```
**React**
```jsx
