Cesium Releases in May 2024

Gabby Getz

In April, we reopened applications for Cesium Ecosystem Grants, shared the continuation of our work with Maxar Intelligence on the US Army’s One World Terrain contract, announced Cesium ion’s Sketchfab integration, and recapped our time at NVIDIA GTC 2024. The team will be at GEOINT Symposium next week—meet us in BOOTH 1831.

Cesium for Unreal 2.5.0 Release

Cesium for Unreal v2.5.0 is now available. Highlights of the release include:

  • Added support for Unreal Engine 5.4.
  • Added support for Cesium ion servers in single user mode. Tokens are not required to stream assets from such servers.

Cesium ion Updates

You can now import 3D models from Sketchfab into Cesium ion to create 3D Tiles, making it easier to create context and content for geospatial experiences. Details are here.

Cesium’s 3D Tiling Pipeline v4.7.1 is now available and includes Point Cloud Tiler fixes: 

  • When reading from LAZ files, it now correctly uses the extended data fields for classification and point_source_id. Previously this resulted in these fields being zero in some cases.
  • Fixed bitmask for legacy point data records' classification field. Could result in incorrect values.

Cesium ion Self-Hosted v1.1 was released and is available for download by licensed customers. This is a maintenance release. View the changelog for details.

In April we highlighted how the Tokyo Metropolitan Digital Twin 3D Viewer uses Cesium to improve residents’ quality of life. Several types of data, including 3D city models, 3D point cloud data within the city, location information of Tokyo Metropolitan buses, river data, 2D data, and videos, are combined in one portal, aiding city planning and disaster prevention. CesiumJS and Cesium ion are utilized as the visualization infrastructure for that 3D viewer.

Written by our community manager in Japan, the story appears first in Japanese, followed by English.
