CesiumJS 1.143

1.143 - 2026年07月01日

Highlights include:

• Added support for the KHR_meshopt_compression glTF extension, including the v1 attribute codec and the COLOR filter. #13553
• Added PathGraphics.materialMode. A value of "PORTIONS" allows visualizing the path in segments with different materials specified by intervals or sampling. Each segment material is determined by the material property value at the corresponding simulation time. The default value of "WHOLE" preserves existing material behavior. #13530
• Fixed a bug that caused crashes when using billboards in environments that replace Promise with custom promise implementations. #13475

See the changelog for the complete list of changes.

CesiumJS 1.142

1.142 - 2026年06月01日

Highlights include:

• Added GeoJsonPrimitive for loading GeoJSON directly into BufferPrimitiveCollections, bypassing the entity/DataSource layer for significantly improved performance with large datasets. CesiumGS/cesium#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. CesiumGS/cesium#13404
• Added blendOption constructor parameter to BufferPointCollection, BufferPolylineCollection, and BufferPolygonCollection, supporting BufferPrimitiveMaterial#color.alpha. Added support for BufferPrimitiveMaterial#outlineColor.alpha to BufferPointCollection. CesiumGS/cesium#13384
• Added experimental support for EXT_mesh_polygon draft glTF extension and 3DTILES_content_gltf_vector draft 3D Tiles extension. CesiumGS/cesium#13478
• Added EdgeDisplayMode enum and edgeDisplayMode property to Model and Cesium3DTileset for controlling how edges from the KhronosGroup/glTF#2479 glTF extension are rendered. Supports three modes: SURFACES_ONLY, SURFACES_AND_EDGES, and EDGES_ONLY (CAD-style wireframe rendering). CesiumGS/cesium#13192

Change Log

1.144 - 2026年08月01日

@​cesium/engine

Additions 🎉

Fixes 🔧

• Fixed a bug in GeocoderViewModel where a duplicate destroy method silently overwrote the first, preventing _suggestionSubscription from being disposed on destroy. #13580
• Fixed geometry clipped by ClippingPlaneCollection or ClippingPolygonCollection still casting shadows. #6261
• Fixed a bug in Transforms.computeMoonFixedToIcrfMatrix which caused the result parameter to not be used. #13463

• Added support for the KHR_meshopt_compression glTF extension, including the v1 attribute codec and the COLOR filter. #13553

Fixes 🔧

• Fixed a bug that caused crashes when using billboards in environments that replace Promise with custom promise implementations. #13475
• Fixed a bug where callbacks registered with Scene.updateHeight would sometimes receive positions computed for other tiles, causing clamped entities to show incorrect heights. #12602
• Invalid glTF sampler wrap modes now fall back to TextureWrap.REPEAT instead of thowing a DeveloperError in development builds. #13562
• Fixed a bug in BufferPointCollection where outlineColor was bleeding into the visible area when set to 0px. #13543

1.142 - 2026年06月01日

Breaking Changes 📣

• The boundingVolume property on BufferPointCollection, BufferPolylineCollection, and BufferPolygonCollection is now defined in world space, not local/model space. #13477

Additions 🎉

• Added GeoJsonPrimitive for loading GeoJSON directly into BufferPrimitiveCollections, bypassing the entity/DataSource layer for significantly improved performance with large datasets. #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. #13404
• Added blendOption constructor parameter to BufferPointCollection, BufferPolylineCollection, and BufferPolygonCollection, supporting BufferPrimitiveMaterial#color.alpha. Added support for BufferPrimitiveMaterial#outlineColor.alpha to BufferPointCollection. #13384
• Added experimental support for EXT_mesh_polygon draft glTF extension and 3DTILES_content_gltf_vector draft 3D Tiles extension. #13478
• Added boundingVolume constructor parameter to BufferPointCollection, BufferPolylineCollection, and BufferPolygonCollection. For larger animated collections, providing a precomputed bounding volume can eliminate the performance cost of automatically updating the bounding volume frequently. #13477
• Added EdgeDisplayMode enum and edgeDisplayMode property to Model and Cesium3DTileset for controlling how edges from the EXT_mesh_primitive_edge_visibility glTF extension are rendered. Supports three modes: SURFACES_ONLY, SURFACES_AND_EDGES, and EDGES_ONLY (CAD-style wireframe rendering). #13192
• Added support for multiple key modifiers in ScreenSpaceEventHandler.setInputAction. #13307
