Cesium Files

1.144 - 2026-08-03

Highlights include:

• To improve CAD-style rendering, CesiumJS adds support for the Bentley-contributed BENTLEY_materials_planar_fill glTF extension, bringing planar polygon fill with depth sorting and coplanar ordering that keep overlapping surfaces from flickering. #13178
• Vector rendering now supports clamping vector polylines and polygons to terrain with screen-space-constant width lines and per-feature styling through Cesium3DTileStyle. This allows massive, tiled visualization of datasets like road connectivity, rivers, and census blocks that correctly overlay on top of terrain. #13627
• Picking of metadata from WMTS imagery providers now works when the imagery layer is draped on 3D Tiles. #13575
• New camera controllers, and a more extensible controller architecture, allow controls to be better targeted to asset inspection and other use cases. #13604
• Models using the EXT_mesh_primitive_edge_visibility extension now load with significantly less JavaScript heap (up to 19x less memory). #13643
