Sample tilesets for learning how to use 3D Tiles and a simple Node.js server for serving tilesets.

These tilesets are generated with 3d-tiles-samples-generator.

Instructions

Clone this repo and install Node.js. 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 Cesium use:

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/'.

Unless otherwise noted use the 3d-tiles branch.

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