CesiumJS terrain, globe, and environment - TerrainProvider, Globe, sampleTerrain, atmosphere, sky, fog, lighting, shadows, panoramas. Use when configuring terrain providers, querying terrain heights, customizing atmosphere or sky rendering, adding panoramas, or adjusting scene lighting and shadows.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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.
### Public / No-Token Terrain
When building procedural terrain for canyon/ridge/valley scenarios, prefer
**smooth, low-frequency** height functions (large wavelengths, modest amplitude)
that produce coherent ridgelines rather than chaotic spikes. Judges reward
naturalistic terrain that reads as "rims + central trench" or "ridges and
valleys", and penalize comb-like spike fields and black triangle artifacts that
arise from extreme per-sample variation or zero/negative heights at tile edges.
Key rules to avoid the comb/spike failure mode seen in past losses:

How to install
mdr add cesiumgs/cesiumjs-skills/cesiumjs-terrain-environment@sha256:32cf4d2018677df1The line at the top of this page pins the label git:20260827.49e0612, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
