What’s new?

1.145 - 2026-09-01

Highlights include:

  • Added support for draping clamped vector tile polygons and polylines onto 3D Tiles, with a new heightReference option and matching read-only property on BufferPrimitiveCollection, inherited by BufferPolygonCollection and BufferPolylineCollection. https://github.com/CesiumGS/cesium/pull/13653
  • ClippingPolygons now use an algorithm, based on the techniques used for vector tiles, that vastly improves quality across distance scales. Warm-up cost is also modestly decreased. https://github.com/CesiumGS/cesium/pull/13654
  • ClippingPolygons now have support for specifying holes (aka islands) within each polygon. This works in inverse clipping workflows as well. https://github.com/CesiumGS/cesium/pull/13660
  • Added experimental IonSnapService for server-side snap-to-geometry against Cesium ion assets backed by a BIM/CAD Database model, and the SnapService interface it implements. https://github.com/CesiumGS/cesium/pull/13682
