Cesium Releases in September 2021

This month we made Cesium ion easier to access by adding the ability to authenticate with Google, GitHub, and Epic Games accounts. Log in to access global 3D content as well as tiling pipelines for your own data.

CesiumJS 1.85 Release 

CesiumJS 1.85 is now available with a number of bug fixes. See the changelog for a full list of updates and links to the discussion & code on each one. You can also subscribe to the Cesium roundup release thread on our community forum to get notifications about our monthly releases.

Cesium for Unreal Updates

The newest release of Cesium for Unreal is now available. Highlights of the release include:

  • Added the ability to define a "Cesium Cartographic Polygon" and then use it to clip away part of a Cesium 3D Tileset.
  • Multiple raster overlays per tileset are now supported.
  • The default materials used to render Cesium 3D Tilesets are now built around Material Layers, making them easier to compose and customize.
  • Added support for using ASceneCapture2D with ACesium3DTileset actors.
  • Added an editor option in ACesium3DTileset to optionally generate smooth normals for glTFs that originally did not have normals.
  • Added an editor option in ACesium3DTileset to disable the creation of physics meshes for its tiles.
  • Added a Refresh button on the Cesium ion Assets panel.
  • Made UCesiumMetadataFeatureTableBlueprintLibrary::GetMetadataValuesAsStringForFeatureID, UCesiumMetadataFeatureTableBlueprintLibrary::GetProperties, and UCesiumMetadataPrimitiveBlueprintLibrary::GetFirstVertexIDFromFaceID callable from Blueprints.
  • Consolidated texture preparation code. Now raster overlay textures can generate mipmaps and the overlay texture preparation can happen partially on the load thread.
  • The Cesium ion Assets panel now has two buttons for imagery assets, allowing the user to select whether the asset should replace the base overlay or be added on top.

See the changelog for a full list of updates. 

Powered by Cesium

This month we got a look at Reality Maps’ model of Golf Club Ruhpolding, a 3D app built on Cesium that allows users to explore a charming golf course in the Alps. 

The app brings together multiple high resolution drone scans of the site, terrain and imagery data from the surrounding mountains, and details about the course itself and about tourist amenities. The site supports visitors in planning their trip.
