What’s new?

1.142 - 2026-06-01

Highlights include:

  • Added GeoJsonPrimitive for loading GeoJSON directly into BufferPrimitiveCollections, bypassing the entity/DataSource layer for significantly improved performance with large datasets. https://github.com/CesiumGS/cesium/pull/13505
  • Added MVTDataProvider for loading Mapbox Vector Tiles (MVT) directly into CesiumJS as 3D Tiles. Supports per-feature styling via Cesium3DTileStyle, feature picking with metadata (getProperty), and automatic property table encoding via EXT_structural_metadata. https://github.com/CesiumGS/cesium/pull/13404
  • Added blendOption constructor parameter to BufferPointCollection, BufferPolylineCollection, and BufferPolygonCollection, supporting BufferPrimitiveMaterial#color.alpha. Added support for BufferPrimitiveMaterial#outlineColor.alpha to BufferPointCollection. https://github.com/CesiumGS/cesium/pull/13384
  • Added experimental support for EXT_mesh_polygon draft glTF extension and 3DTILES_content_gltf_vector draft 3D Tiles extension. https://github.com/CesiumGS/cesium/pull/13478
  • Added EdgeDisplayMode enum and edgeDisplayMode property to Model and Cesium3DTileset for controlling how edges from the https://github.com/KhronosGroup/glTF/pull/2479 glTF extension are rendered. Supports three modes: SURFACES_ONLY, SURFACES_AND_EDGES, and EDGES_ONLY (CAD-style wireframe rendering). https://github.com/CesiumGS/cesium/pull/13192
