CesiumJS Terrain, Globe & Environment

Version baseline: CesiumJS v1.144 | ES module imports (import { ... } from "cesium";)

Terrain Providers

Terrain is served through TerrainProvider implementations. Use async factory methods (fromIonAssetId, fromUrl), not the constructor directly.

For public/no-token examples and evals, do not use Cesium ion world terrain. Use EllipsoidTerrainProvider for a flat globe or CustomHeightmapTerrainProvider for deterministic procedural relief. Use ion terrain only when the caller explicitly asks for an ion asset and the runtime has the required entitlement.
