Cesium Releases in October 2024

Gabby Getz

In September, we introduced the AECO Tech Preview Program, highlighted our summer Refactor, shared that we’ve joined Bentley Systems, featured enhancements to the Three.js 3D Tiles renderer, and announced grant support for the Cesium plugin for Godot.

Visualization of structural metadata and mesh features from 3D Tiles 1.1 is now possible in Three.js with the San Francisco Ferry Building.

We made improvements across Cesium this month. To get notifications about our monthly releases, you can subscribe to the Cesium release roundup thread on our community forum.

CesiumJS 1.122 Release

CesiumJS 1.122 is now available. Highlights of the release include:

  • Added CallbackPositionProperty to allow lazy entity position evaluation. #12170 by new contributor jfayot
  • Added enableVerticalExaggeration option to models. Set this value to false to prevent model exaggeration when Scene.verticalExaggeration is set to a value other than 1.0. #12141 by new contributor timeichfeld-msa
  • Fix Texture errors when using a HTMLVideoElement. #12219
  • Fixed noise in ambient occlusion post process. #12201

For more details, see the changelog.

The new CallbackPositionProperty allows Entities to lazily evaluate a position. Here, it’s used to track a drone flying through the Grand Canyon, as visualized using Google Photorealistic 3D Tiles.

Cesium for Unreal 2.9.0 Release

Cesium for Unreal v2.9.0 is now available. Highlights of the release include:

  • Added SampleHeightMostDetailed function to Cesium3DTileset, which asynchronously queries the height of a tileset at a list of positions. It is callable from both C++ and Blueprints.
  • Drastically reduced tile mesh memory usage in UE 5.3 and 5.4 by working around a bug that causes those engine versions to add more texture coordinate sets than necessary.
  • Fixed a bug where the scale, noData, and default values of a property in EXT_strutural_metadata were not correctly passed to the tileset's material.

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

Cesium for Unity 1.13.0 Release

Cesium for Unity v1.13.0 is now available. Highlights of this release include:

  • Added a new CesiumCameraManager component. It allows configuration of the cameras to use for Cesium3DTileset culling and level-of-detail.
  • Added SampleHeightMostDetailed method to Cesium3DTileset. It asynchronously queries the height of a tileset at a list of positions.
  • Fixed a bug that could cause a NullReferenceException when a Cesium3DTileset was not nested into a game object with a CesiumGeoreference.

Pennoni is moving engineering from graph paper to streaming 3D models with Cesium for Unreal and Google Photorealistic 3D Tiles. Pennoni’s engineers, with collaborating architects, create 3D models for proposed structures using CAD data, point clouds, or photogrammetry. Pennoni loads these directly into Unreal Engine, ensuring accurate placement and lighting with Cesium for Unreal, and streams Google Photorealistic 3D Tiles via Cesium ion for real-world urban context, so the future view is clear.
