Cesium Version 1.43 Released


We are happy to announce the release of Cesium 1.43. This release contains a built-in account key for Cesium ion, our new commercial platform composed of web services and tools to complement CesiumJS’s visualization. The account is free for non-commercial, commercial, and government use until September 1, 2018.

You can also now add Cesium World Terrain to your application. Cesium World Terrain is our new high-resolution global terrain tileset that replaces STK World Terrain, which is deprecated starting today and will be available until September 1, 2018.

Other highlights include:

  • Cesium, the JavaScript library, is now officially renamed to CesiumJS (no code changes required)
  • Fixed bug where KmlDataSource did not use Ellipsoid to convert coordinates. Use options.ellipsoid to pass the ellipsoid to KmlDataSource constructors / loaders.
  • Fixed bug where 3D Tiles Point Clouds would fail in Internet Explorer.

For the full list of changes, see the change log.


  • Randy Meech, most recently CEO of Mapzen, and Neil Trevett of NVIDIA have joined the Cesium advisory board.
  • Using cesium.com’s upcoming 3D tiling pipeline, we tiled Trimble’s point cloud of the historic Pharsalia Cabin for exploring in 3D.
  • Read about how we added CityGML as a supported input format to our upcoming tiling pipeline as part of the OGC Testbed 13.
