A lot has been happening in the Cesium community this month.


New Data and Tools

  • We released a free, hosted, demonstration service with 1-meter resolution terrain of Pennsylvania.
  • The STK World Terrain Tileset has been updated, and now includes the complete SRTM 30-meter resolution dataset.
  • Mark Erikson has posted a sample project demonstrating configuration of webpack and Cesium.
  • Maxime Warnier has posted Cesium Webpack Boilerplate, setting a minimal environment for setting up Cesium with webpack.
  • The newest release of STK improves interoperability with Cesium, allowing developers to author CZML content directly out of STK.
  • Ryan Walkin has built a partial port of Cesium to iOS/OS X, using Swift and Metal, called CesiumKit. He wrote a great guest blog post about how he ported the Cesium graphics engine to Metal and the performance benefits of doing so.
  • Cesium branches are now available now automatically published to S3, via npm, and as a downloadable zip, making it simple to try out the newest features of Cesium even before they are part of an official release.
