AI Summary

The update enforces stricter WebGL requirements for billboards and labels while introducing performance-focused vector primitive APIs and support for ITwin reality data and WebMapTileService imagery.

Key Highlights

  • WebGL 2 required for billboards and labels
  • Added `BufferPointCollection` and `BufferPolylineCollection` APIs
  • Added ITwin Gaussian Splat support
  • Added `GetFeatureInfo` support to WMTS
  • Added `PathGraphics.relativeTo` property

Breaking Changes

  • Billboards and labels now require device support for WebGL 2, or WebGL 1 with ANGLE_instanced_arrays and MAX_VERTEX_TEXTURE_IMAGE_UNITS > 0.

New Features

  • Vector primitive APIs
  • ITwin reality data support
  • WMTS GetFeatureInfo
  • Path reference frames

1.140 - 2026-04-01

Highlights include:

 - Billboards and labels now require device support for WebGL 2, or WebGL 1 with ANGLE_instanced_arrays and MAX_VERTEX_TEXTURE_IMAGE_UNITS > 0. https://github.com/CesiumGS/cesium/issues/13053 https://github.com/CesiumGS/cesium/pull/13253
 - Added experimental, performance-focused vector primitive APIs: BufferPointCollection, BufferPolylineCollection, and BufferPolygonCollection. https://github.com/CesiumGS/cesium/pull/13212
 - Added support for Reality Data of type ITwinPlatform.RealityDataType.GaussianSplat3DTiles to ITwinData.createTilesetForRealityDataId. https://github.com/CesiumGS/cesium/pull/13208
 - Added GetFeatureInfo support to WebMapTileServiceImageryProvider, enabling WebMapTileServiceImageryProvider.pickFeatures for both KVP and RESTful WMTS services. New class parameters include enablePickFeatures, getFeatureInfoFormats, getFeatureInfoUrl, and getFeatureInfoParameters. https://github.com/CesiumGS/cesium/pull/13196
 - Added limited support (via downcasting) for double-precision metadata types in custom shaders. https://github.com/CesiumGS/cesium/pull/13323
 - Added a new experimental property PathGraphics.relativeTo which allows entity PathGraphics to be displayed in a reference frame relative to another entity, or a different reference frame than the entity's Position.ReferenceFrame. https://github.com/CesiumGS/cesium/pull/13223
