Cesium Releases in February 2024

In January, we introduced Cesium World Bathymetry, a new global tileset that opens up visualization and analysis of underwater environments. You can explore some best practices to enhance the visualization of bathymetric terrain using CesiumJS.

Cesium World Bathymetry fuses multiple open data sources into a single bathymetry and topographic terrain tileset.

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 1.114 Release

CesiumJS 1.114 is now available. Highlights of the release include several improvements to interaction with 3D Tiles:

By default, the screen space camera controller will no longer go inside or under instances of Cesium3DTileset. #11581
Clamping to ground, HeightReference.CLAMP_TO_GROUND, and HeightReference.RELATIVE_TO_GROUND now take into account 3D Tilesets. #11604
The Cesium3DTileset.dynamicScreenSpaceError optimization is now enabled by default and tuned to improve performance for street-level horizon views. #11718
Added Cesium3DTileset.getHeight to sample height values of the loaded tiles. #11581
Fog rendering now applies to glTF models and 3D Tiles. #11744

Other changes include:

Added createWorldBathymetryAsync helper function to make it easier to load Bathymetry terrain. #11790
Removed the need for node internal packages http, https, url, and zlib in the Resource class. This means they do not need to be marked external by build tools anymore. #11773
Fixed an issue causing crashes with multiple data sources. #7758 and #9154
Fixed a geometry displacement affecting iOS devices. #7100
