Use when loading compressed or CAD-style glTF/GLB models, controlling edge rendering, playing model animations, positioning particles, or working with geospatial positioning metadata.\"\n---\n# CesiumJS Models, glTF & Particle Effects\n\nVersion baseline: CesiumJS v1.143.\n\n## Quick Reference\n\n| Class | Purpose |\n|---|---|\n| `Model` | Low-level glTF/GLB primitive; positioned via `modelMatrix` |\n| `ModelAnimation` | Active animation instance on a model |\n| `ModelAnimationCollection` | Collection at `model.activeAnimations` |\n| `ModelNode` | Named node with modifiable transform |\n| `ModelFeature` | Per-feature styling/picking for feature-ID models |\n| `EdgeDisplayMode` | Controls draft glTF edge-visibility rendering on Model/Cesium3DTileset |\n| `ParticleSystem` | Billboard-based particle manager (fire, smoke, rain) |\n| `Particle` | Single particle with position, velocity, life |\n| `ParticleBurst` | Scheduled burst of particles |\n| `BoxEmitter` / `CircleEmitter` | Emit within box volume / flat disk |\n| `ConeEmitter` / `SphereEmitter` | Emit from cone tip / within sphere |\n\nThe Entity API exposes models through `ModelGraphics` (see cesiumjs-entities). The Primitive API uses `Model.fromGltfAsync` for full control over `modelMatrix`, animations, and node transforms.\n\n---\n\n## Loading a glTF/GLB Model\n\nAlways use the async factory -- never call the constructor directly.\n\n```js\nimport { Model, Cartesian3, Transforms, HeadingPitchRoll, Math as CesiumMath } from \"cesium\";\n\nconst model = await Model.fromGltfAsync({ url: \"path/to/model.glb\" });\nviewer.scene.primitives.add(model);\n```\n\nCesiumJS 1.143 decodes `KHR_meshopt_compression` automatically, including the\nv1 attribute codec and `COLOR` filter. Do not import a decoder or private loader\nhelper. When loading compressed glTF, CAD-style lines/points/edges, or\nconstant-LOD textures, read [REFERENCE.md](REFERENCE.md) for the complete\nsupport and authoring matrix. The same loader behavior applies to glTF content\ninside 3D Tiles.\n\n### Positioned Model with Heading\n\n```js\nconst position = Cartesian3.fromDegrees(-123.074, 44.050, 5000);\nconst hpr = new HeadingPitchRoll(CesiumMath.toRadians(135), 0, 0);\n\nconst model = await Model.fromGltfAsync({\n  url: \"CesiumAir.glb\",\n  modelMatrix: Transforms.headingPitchRollToFixedFrame(position, hpr),\n  minimumPixelSize: 128,  // never smaller than 128 px on screen\n  maximumScale: 20000,    // cap for minimumPixelSize enlargement\n  scale: 2.0,             // uniform scale multiplier\n});\nviewer.scene.primitives.add(model);\n```\n\n### Key `Model.fromGltfAsync` Options\n\n| Option | Type | Default |\n|---|---|---|\n| `url` | `string\\|Resource` | required |\n| `modelMatrix` | `Matrix4` | `IDENTITY` |\n| `scale` | `number` | `1.0` |\n| `minimumPixelSize` | `number` | `0.0` |\n| `maximumScale` | `number` | -- |\n| `show` | `boolean` | `true` |\n| `color` / `colorBlendMode` / `colorBlendAmount` | `Color` / `ColorBlendMode` / `number` | -- / `HIGHLIGHT` / `0.5` |\n| `edgeDisplayMode` | `EdgeDisplayMode` | `SURFACES_ONLY` |\n| `silhouetteColor` / `silhouetteSize` | `Color` / `number` | `RED` / `0.0` |\n| `shadows` | `ShadowMode` | `ENABLED` |\n| `heightReference` | `HeightReference` | `NONE` |\n| `customShader` | `CustomShader` | -- |\n| `id` | `any` | -- |\n| `allowPicking` | `boolean` | `true` |\n\n---\n\n## Readiness and Lifecycle\n\n`fromGltfAsync` resolves once glTF JSON is parsed, but WebGL resources may still load. Wait for `readyEvent` before accessing animations, nodes, or `boundingSphere`.\n\n```js\nconst model = await Model.fromGltfAsync({ url: \"robot.glb\" });\nviewer.scene.primitives.add(model);\n\nmodel.readyEvent.addEventListener(() => {\n  console.log(\"Bounding sphere:\", model.boundingSphere);\n});\n```\n\n```js\n// Synchronous check\nif (model.ready) { const bs = model.boundingSphere; }\n```\n\n---\n\n## Animations\n\nManaged through `model.activeAnimations` (`ModelAnimationCollection`).\n\n### Play by Name / Play All\n\n```js\nmodel.readyEvent.addEventListener(() => {\n  // Single animation\n  const anim = model.activeAnimations.add({\n    name: \"Walk\",                          // glTF animation name\n    loop: Cesium.ModelAnimationLoop.REPEAT, // NONE | REPEAT | MIRRORED_REPEAT\n    multiplier: 1.0,                       // playback speed (must be > 0)\n  });\n  anim.start.addEventListener((m, a) => console.log(`Started: ${a.name}`));\n\n  // Or play all animations at once\n  model.activeAnimations.addAll({\n    loop: Cesium.ModelAnimationLoop.REPEAT,\n    multiplier: 0.5,\n  });\n});\n```\n\nAdditional `add` options: `index`, `reverse`, `startTime`, `stopTime`, `delay`, `removeOnStop`, `animationTime` (custom time callback).\n\n### Animation Events\n\n```js\nanimation.start.addEventListener((model, animation) => { });\nanimation.update.addEventListener((model, animation, time) => { });\nanimation.stop.addEventListener((model, animation) => { });\n// Collection-level\nmodel.activeAnimations.animationAdded.addEventListener((model, anim) => { });\n```\n\n```js\nmodel.activeAnimations.remove(animation); // remove one\nmodel.activeAnimations.removeAll();        // remove all\n```\n\n---\n\n## Model Nodes\n\nOverride named node transforms for procedural animation (e.g., turret rotation).\n\n```js\nmodel.readyEvent.addEventListener(() => {\n  const node = model.getNode(\"Turret\");\n  node.matrix = Cesium.Matrix4.fromScale(\n    new Cesium.Cartesian3(5.0, 1.0, 1.0), node.matrix\n  );\n});\n```\n\nProperties: `name` (read-only), `id` (read-only index), `show` (boolean), `matrix` (Matrix4 -- set to `undefined` to restore original and re-enable glTF animations).\n\n---\n\n## Coloring, Silhouettes, and Feature Picking\n\n```js\n// Tint + silhouette\nmodel.color = Cesium.Color.RED.withAlpha(0.5);\nmodel.colorBlendMode = Cesium.ColorBlendMode.MIX;\nmodel.colorBlendAmount = 0.5;\nmodel.silhouetteColor = Cesium.Color.YELLOW;\nmodel.silhouetteSize = 2.0;\n```\n\n### Edge Display Mode (Experimental, 1.142+)\n\nFor glTF assets using the draft `EXT_mesh_primitive_edge_visibility` extension,\n`EdgeDisplayMode` controls whether extension-provided edges are hidden, composited\nover surfaces, or rendered alone. Models without the extension are unaffected.\n\n```js\nimport { EdgeDisplayMode, Model } from \"cesium\";\n\nconst model = await Model.fromGltfAsync({\n  url: \"/models/cad-part.glb\",\n  edgeDisplayMode: EdgeDisplayMode.SURFACES_AND_EDGES,\n});\nviewer.scene.primitives.add(model);\n\nmodel.edgeDisplayMode = EdgeDisplayMode.EDGES_ONLY;       // CAD-style wireframe\nmodel.edgeDisplayMode = EdgeDisplayMode.SURFACES_ONLY;    // default\n```\n\nWhen a glTF has `EXT_mesh_features` or `EXT_structural_metadata`, picking returns a `ModelFeature`:\n\n```js\nconst handler = new Cesium.ScreenSpaceEventHandler(viewer.scene.canvas);\nhandler.setInputAction((movement) => {\n  const picked = viewer.scene.pick(movement.endPosition);\n  if (picked instanceof Cesium.ModelFeature) {\n    picked.getPropertyIds().forEach((name) => {\n      console.log(`${name}: ${picked.getProperty(name)}`);\n    });\n    picked.color = Cesium.Color.YELLOW;\n  }\n}, Cesium.ScreenSpaceEventType.MOUSE_MOVE);\n```\n\n---\n\n## Height Reference\n\n```js\n// Primitive API -- scene is required for height reference\nconst model = await Model.fromGltfAsync({\n  url: \"truck.glb\",\n  heightReference: Cesium.HeightReference.CLAMP_TO_GROUND,\n  scene: viewer.scene,\n});\n\n// Entity API\nviewer.entities.add({\n  position: Cartesian3.fromDegrees(-75.59, 40.03),\n  model: { uri: \"truck.glb\", heightReference: Cesium.HeightReference.CLAMP_TO_GROUND },\n});\n```\n\nValues: `NONE`, `CLAMP_TO_GROUND`, `RELATIVE_TO_GROUND`, `CLAMP_TO_TERRAIN`, `RELATIVE_TO_TERRAIN`, `CLAMP_TO_3D_TILE`, `RELATIVE_TO_3D_TILE`.\n\n---\n\n## Particle Systems\n\n`ParticleSystem` renders billboard-based effects. Position with `modelMatrix` (world) and `emitterModelMatrix` (local offset).\n\n### Smoke Trail\n\n```js\nimport { ParticleSystem, CircleEmitter, Color, Cartesian2, Transforms, Cartesian3 } from \"cesium\";\n\nconst smokeSystem = new ParticleSystem({\n  image: \"smoke.png\",\n  startColor: Color.LIGHTGRAY.withAlpha(0.7),\n  endColor: Color.WHITE.withAlpha(0.0),\n  startScale: 1.0,\n  endScale: 5.0,\n  emissionRate: 10,\n  minimumSpeed: 1.0,\n  maximumSpeed: 4.0,\n  minimumParticleLife: 1.2,\n  maximumParticleLife: 3.0,\n  imageSize: new Cartesian2(25, 25), // pixel size\n  emitter: new CircleEmitter(2.0),   // radius in meters\n  modelMatrix: Transforms.eastNorthUpToFixedFrame(Cartesian3.fromDegrees(-75.157, 39.978)),\n  lifetime: 16.0,\n  loop: true,\n});\nviewer.scene.primitives.add(smokeSystem);\n```\n\n### Emitter Types\n\n```js\nimport { BoxEmitter, CircleEmitter, ConeEmitter, SphereEmitter } from \"cesium\";\n\nnew BoxEmitter(new Cesium.Cartesian3(10, 10, 10));  // 3D box, velocity outward\nnew CircleEmitter(2.0);                              // flat disk, velocity +Z\nnew ConeEmitter(Cesium.Math.toRadians(30));          // cone tip, velocity toward base\nnew SphereEmitter(5.0);                              // sphere, velocity radiates out\n```\n\n### Particle Bursts\n\n```js\nconst firework = new ParticleSystem({\n  image: getParticleCanvas(),\n  startColor: Color.RED,\n  endColor: Color.RED.withAlpha(0.0),\n  particleLife: 1.0,\n  speed: 100.0,\n  imageSize: new Cartesian2(7, 7),\n  emissionRate: 0,  // bursts only\n  emitter: new SphereEmitter(0.1),\n  bursts: [\n    new Cesium.ParticleBurst({ time: 0.0, minimum: 100, maximum: 200 }),\n    new Cesium.ParticleBurst({ time: 2.0, minimum: 50, maximum: 100 }),\n    new Cesium.ParticleBurst({ time: 4.0, minimum: 200, maximum: 300 }),\n  ],\n  lifetime: 6.0,\n  loop: false,\n  modelMatrix: Transforms.eastNorthUpToFixedFrame(Cartesian3.fromDegrees(-75.597, 40.038)),\n});\nviewer.scene.primitives.add(firework);\n```\n\n### Update Callback (Gravity / Wind)\n\nThe `updateCallback` runs per-particle per-frame for forces like gravity.\n\n```js\nconst gravityScratch = new Cesium.Cartesian3();\nfunction applyGravity(particle, dt) {\n  Cesium.Cartesian3.normalize(particle.position, gravityScratch);\n  Cesium.Cartesian3.multiplyByScalar(gravityScratch, -9.8 * dt, gravityScratch);\n  particle.velocity = Cesium.Cartesian3.add(particle.velocity, gravityScratch, particle.velocity);\n}\n\nconst system = new ParticleSystem({\n  image: \"smoke.png\",\n  emissionRate: 20,\n  emitter: new ConeEmitter(Cesium.Math.toRadians(45)),\n  updateCallback: applyGravity,\n  modelMatrix: Transforms.eastNorthUpToFixedFrame(Cartesian3.fromDegrees(-105, 40, 1000)),\n});\nviewer.scene.primitives.add(system);\n```\n\n---\n\n## Attaching Particles to a Moving Model\n\nSync `modelMatrix` each frame via `scene.preUpdate`. Use `emitterModelMatrix` for a local offset (e.g., exhaust pipe).\n\n```js\nconst entity = viewer.entities.add({\n  position: sampledPosition,\n  orientation: new Cesium.VelocityOrientationProperty(sampledPosition),\n  model: { uri: \"truck.glb\", minimumPixelSize: 64 },\n});\n\n// Local offset to exhaust pipe\nconst trs = new Cesium.TranslationRotationScale();\ntrs.translation = new Cesium.Cartesian3(-4.0, 0.0, 1.4);\nconst emitterModelMatrix = Cesium.Matrix4.fromTranslationRotationScale(trs, new Cesium.Matrix4());\n\nconst exhaust = new ParticleSystem({\n  image: \"smoke.png\",\n  startColor: Color.GRAY.withAlpha(0.7),\n  endColor: Color.TRANSPARENT,\n  emissionRate: 8,\n  speed: 2.0,\n  particleLife: 1.5,\n  imageSize: new Cartesian2(20, 20),\n  emitter: new CircleEmitter(0.5),\n  emitterModelMatrix: emitterModelMatrix,\n});\nviewer.scene.primitives.add(exhaust);\n\nviewer.scene.preUpdate.addEventListener((scene, time) => {\n  exhaust.modelMatrix = entity.computeModelMatrix(time, new Cesium.Matrix4());\n});\n```\n\n---\n\n## Canvas-Based Particle Images\n\nGenerate particle textures dynamically instead of loading image files.\n\n```js\nfunction createCircleImage() {\n  const c = document.createElement(\"canvas\");\n  c.width = c.height = 20;\n  const ctx = c.getContext(\"2d\");\n  ctx.beginPath();\n  ctx.arc(10, 10, 10, 0, Math.PI * 2);\n  ","tagline":"CesiumJS models, glTF, and particle effects - Model, KHR_meshopt_compression, CAD glTF extensions, EdgeDisplayMode, ModelAnimation, ModelNode, ParticleSystem, emitters, GPM extensions.
