Cesium Version 1.15 Released


We are pleased to announce the release of Cesium 1.15. Highlights include:

  • Support for glTF 1.0 and the KHR_binary_glTF and KHR_materials_common extensions. Also, updated the online model converter to output glTF 1.0.
  • Decreased GPU memory usage in BillboardCollection and LabelCollection by using WebGL instancing.
  • New CZML examples thanks to Tiff Lu and Adam Cole from the University of Pennsylvania.

For more details and the full list of changes, see the change log.

October was a busy month for the Cesium community:


3D Models

  • The glTF 1.0 draft spec is now available. See the press release and plans for Cesium. We are happy to be one of the primary contributors to the spec and to have the first glTF 1.0 implementation!
  • Released obj2gltf to convert OBJ models to glTF.
  • Released wetzel, a tool to generate Markdown documentation from JSON Schema, which we used for the glTF spec.
  • A few Cesium team members will be at the NYC WebGL Meetup on Tuesday, November 3, to present the latest on glTF.
