CesiumJS 1.87.1

1.87.1 - 2021-11-09

Highlights include:

• Added experimental implementations of 3D Tiles Next. The following extensions are supported:
  • 3DTILES_content_gltf for using glTF models directly as tile contents
  • 3DTILES_metadata for adding structured metadata to tilesets, tiles, or groups of tile content
  • EXT_mesh_features for adding feature identification and feature metadata to glTF models
  • 3DTILES_implicit_tiling for a compact representation of quadtrees and octrees
  • 3DTILES_bounding_volume_S2 for S2 bounding volumes
  • 3DTILES_multiple_contents for storing multiple contents within a single tile
• Added ModelExperimental, a new experimental architecture for loading glTF models. It is disabled by default; set ExperimentalFeatures.enableModelExperimental = true to enable it.
• Added CustomShader class for styling Cesium3DTileset or ModelExperimental with custom GLSL shaders
• Added Sandcastle examples for 3D Tiles Next: Photogrammetry Classification, CDB Yemen, and S2 Globe
