  • Added MVTDataProvider for loading Mapbox Vector Tiles as 3D Tiles with feature picking and styling.
  • Added blendOption constructor parameter to BufferPrimitiveCollections supporting alpha transparency.
  • Added experimental support for EXT_mesh_polygon and 3DTILES_content_gltf_vector extensions.
  • Added EdgeDisplayMode enum for controlling CAD-style wireframe rendering on Models.

New Features

  • GeoJsonPrimitive for high-performance loading
  • MVTDataProvider for Mapbox Vector Tiles
  • BufferPrimitive blendOption support
  • Experimental mesh polygon support
  • EdgeDisplayMode for CAD-style rendering

Full Release Notes

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
