Cesium Releases in May 2025

Josh Rouzer

In April, we attended the 40th Space Symposium, hosted the Philly Postgres meetup and PhillyCHI UX panel, and released the full agenda for the Cesium Developer Conference. (Will we see you there?) Today we announced 3D Tiles for Godot, an open source plugin for Godot Engine built by Battle Road through the support of a Cesium Ecosystem Grant.

CesiumJS 1.129 Release

CesiumJS 1.129 is now available. Highlights of the release include:

  • VoxelProvider.minimumBounds and .maximumBounds are now specified as physical values, rather than shape space values. #12592 
  • Added Material with Custom GLSL Sandbox Demo. #12549 
  • QuadtreePrimitive.updateHeights now converts position to Cartographic before invoking the callback, ensuring compatibility with change introduced by commit 53889cb and preventing unnecessary computation. #12555 
  • Fixed Polyline*MaterialProperty width artifacts (reverted #12434). #12506 

For more details, see the changelog.

Cesium for Unreal 2.16.0 Release

Cesium for Unreal v2.16.0 is now available. Highlights of this release include:

  • Added the ability to query the Cesium ion geocoder from Blueprints to resolve place names and addresses to longitude and latitude. 
  • Added UCesiumMetadataPickingBlueprintLibrary::FindPropertyTableProperty to search for a FCesiumPropertyTableProperty by name on a given UPrimitiveComponent. 
  • The request cache will now use FPaths::ProjectUserDir instead of FPaths::EngineUserDir on non-Android and non-iOS platforms, fixing a permissions issue in Development builds. 
  • Fixed a linking issue introduced in v2.15.0 in GoogleTilesTestSetup. 
  • Point cloud tiles will now be upsampled for raster overlays, fixing an issue where applying a raster overlay to a point cloud tileset would cause holes to appear. 
  • Fixed a crash caused by invalid I3dm headers. 

Check the Cesium for Unreal release and the Cesium for Unreal Samples release for the full list of updates.

Buendea uses Cesium Moon Terrain to support NASA’s Advanced Operations Concepts Lab (NAOCL), ensuring astronauts’ virtual training accurately reflects the lunar environments they’ll encounter when they leave home. XR Operations Support System (XOSS) is a collaboration between Buendea and NAOCL, based out of Johnson Space Center (JSC) in Houston, Texas, USA. XOSS users have the entire Moon in their simulation and can further immerse themselves in nine potential landing and habitation sites near the lunar South Pole, where Cesium Moon Terrain has its highest resolution data and Buendea has added additional high-res surface data.
