Cesium Version 1.31 Released


We are happy to announce the release of Cesium 1.31. Highlights include

  • Added compressed texture support for glTF models and imagery layers.
  • Added support for Scene.pickPosition in Columbus view and 2D.
  • Added support for depth picking translucent primitives when Scene.pickTranslucentDepth is true.
  • Fixed an issue where the camera would zoom past an object and flip to the other side of the globe.
  • Added support for GroundPrimitive on browsers and hardware without the EXT_frag_depth extension.

For the full list of changes, see the change log.
