Cesium ion now supports uploading ZIP files, which greatly reduces the upload time and bandwidth usage for most source data types. ZIP files also let you get more out of your existing ion storage, since it uses compressed file size when calculating storage quota. While the bandwidth and storage savings...

With the most recent CesiumJS release, terrain and imagery now load 32% faster on average and request significantly fewer tiles - meaning your data usage in Cesium ion is about to go down. This is part of a continuing effort to optimize CesiumJS for the smoothest end user experience across...

• CesiumJS

We are happy to announce the release of Cesium 1.55. As part of this release, we’ve revamped terrain and imagery rendering, resulting in terrain and imagery loading an average of 33% faster (with some scenes loading twice as fast!) and streaming an average of 33% less data. Highlights include: Updated...

At Geopipe we’ve built a tool called ContextSnap that can stream entire cities into your browser using Cesium and 3D Tiles. With ContextSnap you can navigate a 3D copy of a city within your browser and click on buildings and other objects to see semantic information: height, number of floors,...

Point clouds now load faster than ever in Cesium thanks to Google Draco compression, which we’ve added to the Cesium ion 3D tiling pipeline. Our 3D tiling pipeline efficiently tiles full-resolution point clouds into 3D Tiles, an OGC community standard, so they can be streamed into CesiumJS for visualization and...

Cesium ion now supports uploading glTF models as input into our 3D tiling pipeline, unlocking a bevy of massive 3D content for streaming to Cesium applications. Because of glTF’s emphasis on interoperability, there’s a good chance that your tools can already export glTF models. 3D Tiles is built on glTF,...

The latest issue of magazine makes the case that open source and open standards will drive the future of GEOINT in its cover story “An Open Frontier” by Matt Alderton—and prominently features Cesium as part of this movement. We couldn’t agree more with this assessment. With the ever-growing supply of...

The Khronos Group recently gave Patrick a Khronie Award for his work advancing glTF! We couldn’t be prouder. glTF is the open standard 3D runtime format for 3D models. Its continued improvement and advancement is thanks to the hard work of the 30+ members of the Khronos 3D Formats Working...
