CesiumJS models, glTF, and particle effects - Model, KHR_meshopt_compression, CAD glTF extensions, EdgeDisplayMode, ModelAnimation, ModelNode, ParticleSystem, emitters, GPM extensions. Use when loading compressed or CAD-style glTF/GLB models, controlling edge rendering, playing model animations, positioning particles, or working with geospatial positioning metadata.
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 Models, glTF & Particle Effects Version baseline: CesiumJS v1.144. ## Quick Reference | Class | Purpose | |---|---| | `Model` | Low-level glTF/GLB primitive; positioned via `modelMatrix` | | `ModelAnimation` | Active animation instance on a model | | `ModelAnimationCollection` | Collection at `model.activeAnimations` | | `ModelNode` | Named node with modifiable transform | | `ModelFeature` | Per-feature styling/picking for feature-ID models | | `EdgeDisplayMode` | Controls draft glTF edge-visibility rendering on Model/Cesium3DTileset | | `ParticleSystem` | Billboard-based particle manager (fire, smoke, rain) | | `Particle` | Single particle with position, velocity, life | | `ParticleBurst` | Scheduled burst of particles | | `BoxEmitter` / `CircleEmitter` | Emit within box volume / flat disk | | `ConeEmitter` / `SphereEmitter` | Emit from cone tip / within sphere | The Entity API exposes models through `ModelGraphics` (see cesiumjs-entities). The Primitive API uses `Model.fromGltfAsync` for full control over `modelMatrix`, animations, and node transforms. --- ## Loading a glTF/GLB Model Always use the async factory -- never call the constructor directly. ```js …

How to install
mdr add cesiumgs/cesiumjs-skills/cesiumjs-models-particles@sha256:d7a34ac7ee209fcdThe 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.
