## README

<p align="center"><img src="https://github.com/CesiumGS/3d-tiles/blob/master/figures/Cesium3DTiles.png" /></p>

Sample tilesets for learning how to use [3D Tiles](https://github.com/CesiumGS/3d-tiles) and a simple Node.js server for serving tilesets.

These tilesets are generated with [3d-tiles-samples-generator](https://github.com/CesiumGS/3d-tiles-validator/tree/master/samples-generator). License information can be found in each sample's README.

## Instructions

Clone this repo and install [Node.js](http://nodejs.org/).  From the root directory of this repo, run:
```
npm install
```

Then to host the tilesets locally, run:
```
npm start
```

The tilesets are hosted at `http://localhost:8003/tilesets/`.

To load a tileset with CesiumJS use:

```javascript
var viewer = new Cesium.Viewer('cesiumContainer');

var tileset = viewer.scene.primitives.add(new Cesium.Cesium3DTileset({
    url : 'http://localhost:8003/tilesets/TilesetWithDiscreteLOD/tileset.json'
}));

viewer.zoomTo(tileset, new Cesium.HeadingPitchRange(0, -0.5, 0));
```

When testing tilesets using this server that you do not want to accidentally push to git, create a `localTilesets` directory, place the tilesets there, and access like `'http://localhost:8003/localTilesets/GitIgnoredTileset/'`.

See the `README.md` in each tileset's directory for further instructions and usage restrictions.
