CesiumJS 1.146

1.146 - 2026-10-01

Starting with version 1.146, CesiumJS now publishes a new package, @cesium/core, containing the math, geometry, time, and utility classes that were previously part of @cesium/engine. #13805

Highlights include:

• Added vectorBlendOption to Cesium3DTileset, for selecting opaque or translucent modes. blendOption can now also be changed after construction on BufferPointCollection, BufferPolylineCollection, and BufferPolygonCollection. #13764
• Added .pickObject getter/setter to BufferPrimitive. #13811
• Added batch .setPositions method to BufferPrimitiveCollection, improving performance when animating vertex positions on a range of many point, line, or polygon primitives. #13590
