We are pleased to announce the release of Cesium 1.13. Highlights include:

  • Improved Cesium compatibility on mobile GPUs, such as the Mali-400MP.
  • Support for GroundPrimitive which works much like Primitive but drapes geometry over terrain.
  • Support for z-ordering of GroundPrimitive instances via Scene.groundPrimitives.

For more details and the full list of changes, see the change log.
