Use when rendering performance-critical static or vector geometry, loading GeoJSON without entities, creating custom shapes, batching draw calls, or using low-level collections.\"\n---\n# CesiumJS Primitives & Geometry\n\n> **Applies to:** CesiumJS v1.143+ (ES module imports, `??` instead of `defaultValue`)\n\n## Architecture\n\nThe Primitive API is the low-level rendering layer beneath the Entity API, trading convenience for performance.\n\n**Core formula:** `Primitive = GeometryInstance[] + Appearance`\n\n- **GeometryInstance** -- positions a Geometry in world space with per-instance attributes (color, show).\n- **Geometry** -- vertex data describing a shape (polygon, box, ellipsoid, etc.).\n- **Appearance** -- GLSL shaders + render state + optional Material that shade the geometry.\n\nPrimitives are **immutable after first render** -- geometry cannot change, but per-instance attributes update via `primitive.getGeometryInstanceAttributes(id)`.\n\n## Primitive\n\n```js\nimport {\n  Viewer, Primitive, GeometryInstance, EllipseGeometry,\n  EllipsoidSurfaceAppearance, Material, Cartesian3, Math as CesiumMath,\n} from \"cesium\";\n\nconst viewer = new Viewer(\"cesiumContainer\");\nconst scene = viewer.scene;\n\nconst primitive = scene.primitives.add(new Primitive({\n  geometryInstances: new GeometryInstance({\n    geometry: new EllipseGeometry({\n      center: Cartesian3.fromDegrees(-100.0, 40.0),\n      semiMinorAxis: 250000.0,\n      semiMajorAxis: 400000.0,\n      rotation: CesiumMath.PI_OVER_FOUR,\n      vertexFormat: EllipsoidSurfaceAppearance.VERTEX_FORMAT, // must match appearance\n    }),\n    id: \"myEllipse\", // returned by Scene.pick()\n  }),\n  appearance: new EllipsoidSurfaceAppearance({ material: Material.fromType(\"Stripe\") }),\n}));\n```\n\n### Key Options\n\n| Option | Default | Purpose |\n|---|---|---|\n| `geometryInstances` | -- | Single instance or array |\n| `appearance` | -- | Shading (Appearance subclass) |\n| `show` | `true` | Toggle visibility |\n| `modelMatrix` | `Matrix4.IDENTITY` | Transform all instances |\n| `asynchronous` | `true` | Build geometry on web worker |\n| `releaseGeometryInstances` | `true` | Free geometry after GPU upload |\n| `allowPicking` | `true` | `false` saves GPU memory |\n| `shadows` | `ShadowMode.DISABLED` | Cast/receive shadows |\n\n## Batching Multiple Instances\n\nAll instances in one Primitive share a single draw call.\n\n```js\nimport {\n  Primitive, GeometryInstance, RectangleGeometry, EllipseGeometry,\n  PerInstanceColorAppearance, ColorGeometryInstanceAttribute,\n  Cartesian3, Rectangle, Color,\n} from \"cesium\";\n\nscene.primitives.add(new Primitive({\n  geometryInstances: [\n    new GeometryInstance({\n      geometry: new RectangleGeometry({\n        rectangle: Rectangle.fromDegrees(-140, 30, -100, 40),\n        vertexFormat: PerInstanceColorAppearance.VERTEX_FORMAT,\n      }),\n      id: \"rect\",\n      attributes: { color: ColorGeometryInstanceAttribute.fromColor(Color.RED.withAlpha(0.5)) },\n    }),\n    new GeometryInstance({\n      geometry: new EllipseGeometry({\n        center: Cartesian3.fromDegrees(-80, 35),\n        semiMinorAxis: 200000.0,\n        semiMajorAxis: 300000.0,\n        vertexFormat: PerInstanceColorAppearance.VERTEX_FORMAT,\n      }),\n      id: \"ellipse\",\n      attributes: { color: ColorGeometryInstanceAttribute.fromColor(Color.BLUE.withAlpha(0.5)) },\n    }),\n  ],\n  appearance: new PerInstanceColorAppearance(),\n}));\n```\n\n## Updating Per-Instance Attributes\n\n```js\nimport { ColorGeometryInstanceAttribute, ShowGeometryInstanceAttribute } from \"cesium\";\n\n// Wait for async geometry compilation\nconst removeListener = scene.postRender.addEventListener(() => {\n  if (!primitive.ready) return;\n  const attrs = primitive.getGeometryInstanceAttributes(\"rect\");\n  attrs.color = ColorGeometryInstanceAttribute.toValue(Color.YELLOW);\n  attrs.show = ShowGeometryInstanceAttribute.toValue(true);\n  removeListener();\n});\n```\n\n## PrimitiveCollection\n\nNestable container -- `scene.primitives` is itself a PrimitiveCollection.\n\n```js\nimport { PrimitiveCollection, BillboardCollection, LabelCollection } from \"cesium\";\n\nconst group = new PrimitiveCollection();\ngroup.add(new BillboardCollection());\ngroup.add(new LabelCollection());\nscene.primitives.add(group);\ngroup.show = false; // toggle all children\n```\n\n## Choosing a Vector Data Path\n\n| Need | Use |\n|---|---|\n| Entity lifecycle, clustering, per-entity styling, time-dynamic values | `GeoJsonDataSource` in `cesiumjs-entities` |\n| One large GeoJSON object with low overhead and primitive-level performance | `GeoJsonPrimitive` in this skill |\n| Tiled vector data, 3D Tiles LOD, metadata styling, feature picking | `MVTDataProvider` in `cesiumjs-3d-tiles` |\n| Fully manual high-throughput point/polyline/polygon buffers | `BufferPointCollection`, `BufferPolylineCollection`, `BufferPolygonCollection` |\n\n## Buffer Primitive Collections (Experimental, 1.140+)\n\nUse `BufferPointCollection`, `BufferPolylineCollection`, and `BufferPolygonCollection`\nfor very large vector datasets where Entity/DataSource overhead is too high. These\nAPIs were introduced in 1.140 (#13212) and refined through 1.142; they are\nexperimental and use flyweight primitive objects: reuse one `BufferPoint`,\n`BufferPolyline`, or `BufferPolygon` when adding or iterating thousands of items.\n\n```js\nimport {\n  BlendOption,\n  BoundingSphere,\n  BufferPoint,\n  BufferPointCollection,\n  BufferPointMaterial,\n  Cartesian3,\n  Color,\n} from \"cesium\";\n\nconst positions = [\n  Cartesian3.fromDegrees(-75.16, 39.95),\n  Cartesian3.fromDegrees(-73.98, 40.75),\n];\n\nconst points = scene.primitives.add(new BufferPointCollection({\n  primitiveCountMax: positions.length,\n  allowPicking: true,\n  blendOption: BlendOption.TRANSLUCENT,\n  boundingVolume: BoundingSphere.fromPoints(positions), // world space in 1.142+\n}));\n\nconst point = new BufferPoint();\nconst material = new BufferPointMaterial({\n  color: Color.CYAN.withAlpha(0.65),\n  outlineColor: Color.WHITE.withAlpha(0.9),\n  outlineWidth: 2,\n  size: 10,\n});\n\npositions.forEach((position, featureId) => {\n  points.add({\n    position,\n    featureId,\n    material,\n  }, point);\n});\n\nconst picked = scene.pick(windowPosition);\nif (picked?.collection === points) {\n  console.log(picked.index, picked.primitive.featureId);\n}\n```\n\n> **Breaking change (1.141, #13448):** `BufferPrimitiveCollection.modelMatrix`,\n> `boundingVolume`, and `boundingVolumeWC` are now **readonly** -- you may mutate\n> the object in place, but reassigning the property (`collection.modelMatrix = ...`)\n> throws. Update the existing matrix/volume instead of swapping in a new one.\n\n1.142 notes:\n- `boundingVolume` is now world-space, not local/model-space. If you provide it manually, include the collection `modelMatrix` transform yourself.\n- Providing `boundingVolume` skips automatic recomputation; this helps large animated collections but makes you responsible for keeping the volume valid.\n- `blendOption` is supported on all three buffer collections and enables alpha from `BufferPrimitiveMaterial#color`; `BufferPointCollection` also honors `outlineColor.alpha`.\n- Use `BlendOption.OPAQUE` only when every material is fully opaque; use `TRANSLUCENT` or mixed blending when alpha varies.\n\nIn 1.143, `BufferPointCollection` no longer leaks `outlineColor` into the fill\nwhen `outlineWidth` is `0`. Set the width to `0` to disable outlines; remove\ntransparent-outline workarounds that would otherwise complicate batching.\n\n## GeoJsonPrimitive (Experimental, 1.142+)\n\n`GeoJsonPrimitive` loads GeoJSON directly into buffer primitive collections,\nbypassing `GeoJsonDataSource` and the Entity layer. Prefer it for large static\nor bulk-updated vector datasets. Keep using `GeoJsonDataSource` when you need\nEntity conveniences, time-dynamic properties, clustering, or DataSource lifecycle\nintegration.\n\n```js\nimport { GeoJsonPrimitive } from \"cesium\";\n\nconst counties = await GeoJsonPrimitive.fromUrl(\"/data/counties.geojson\", {\n  allowPicking: true,\n});\nscene.primitives.add(counties);\n\nconsole.log(counties.featureCount);\nconsole.log(counties.points);    // BufferPointCollection | undefined\nconsole.log(counties.polylines); // BufferPolylineCollection | undefined\nconsole.log(counties.polygons);  // BufferPolygonCollection | undefined\n\n// Picking returns the GeoJsonPrimitive pick object, including source properties.\nconst picked = scene.pick(windowPosition);\nif (picked?.parentPrimitive === counties) {\n  const featureId = picked.primitive.featureId;\n  console.log(counties.getId(featureId));\n  console.log(counties.getProperties(featureId));\n}\n```\n\n`GeoJsonPrimitive.fromGeoJson(parsedObject)` is available when the GeoJSON is\nalready in memory. Source feature IDs are exposed through `ids`/`getId()`, and\nsource properties through `properties`/`getProperties()`.\n\n## Built-in Geometry Types (31)\n\nAll geometries take shape parameters and a `vertexFormat` matching the Appearance. Most have a paired `*OutlineGeometry`. Outlines require a separate Primitive.\n\n### Filled + Outline Pattern\n\n```js\nimport {\n  Primitive, GeometryInstance, PolygonGeometry, PolygonOutlineGeometry,\n  PolygonHierarchy, PerInstanceColorAppearance, ColorGeometryInstanceAttribute,\n  Cartesian3, Color,\n} from \"cesium\";\n\nconst positions = Cartesian3.fromDegreesArray([-115, 37, -115, 32, -107, 33, -102, 35]);\n\n// Fill primitive\nscene.primitives.add(new Primitive({\n  geometryInstances: new GeometryInstance({\n    geometry: new PolygonGeometry({\n      polygonHierarchy: new PolygonHierarchy(positions),\n      vertexFormat: PerInstanceColorAppearance.VERTEX_FORMAT,\n    }),\n    attributes: { color: ColorGeometryInstanceAttribute.fromColor(Color.CYAN.withAlpha(0.5)) },\n  }),\n  appearance: new PerInstanceColorAppearance(),\n}));\n\n// Outline primitive (separate draw call)\nscene.primitives.add(new Primitive({\n  geometryInstances: new GeometryInstance({\n    geometry: new PolygonOutlineGeometry({ polygonHierarchy: new PolygonHierarchy(positions) }),\n    attributes: { color: ColorGeometryInstanceAttribute.fromColor(Color.WHITE) },\n  }),\n  appearance: new PerInstanceColorAppearance({ flat: true }),\n}));\n```\n\n### Geometry Catalog\n\nEvery `XxxGeometry` has a matching `XxxOutlineGeometry` unless noted.\n\n**Surface** (work with GroundPrimitive): `CircleGeometry`, `CorridorGeometry`, `EllipseGeometry`, `PolygonGeometry`, `RectangleGeometry`.\n\n**Volume** (need `modelMatrix`): `BoxGeometry` (`fromDimensions()`), `CylinderGeometry` (cone when topRadius != bottomRadius), `EllipsoidGeometry`, `SphereGeometry`, `FrustumGeometry`, `PlaneGeometry`.\n\n**Path**: `CorridorGeometry` (buffered path), `PolylineVolumeGeometry` (2D shape extruded along path), `WallGeometry` (vertical curtain).\n\n**Polygon**: `PolygonGeometry` (holes via `PolygonHierarchy`), `CoplanarPolygonGeometry` (non-Earth-surface).\n\n**Line** (no outline): `PolylineGeometry` (pixel-width), `SimplePolylineGeometry` (1px), `GroundPolylineGeometry` (GroundPolylinePrimitive only).\n\n### Positioning Off-Surface Geometry\n\nBox, Ellipsoid, Cylinder, and Frustum need a `modelMatrix` on the GeometryInstance.\n\n```js\nimport { GeometryInstance, BoxGeometry, PerInstanceColorAppearance,\n  ColorGeometryInstanceAttribute, Cartesian3, Matrix4, Transforms, Color } from \"cesium\";\n\nconst modelMatrix = Matrix4.multiplyByTranslation(\n  Transforms.eastNorthUpToFixedFrame(Cartesian3.fromDegrees(-105, 40)),\n  new Cartesian3(0, 0, 250000), new Matrix4(),\n);\nnew GeometryInstance({\n  geometry: BoxGeometry.fromDimensions({\n    dimensions: new Cartesian3(400000, 300000, 500000),\n    vertexFormat: PerInstanceColorAppearance.VERTEX_FORMAT,\n  }),\n  modelMatrix,\n  id: \"floatingBox\",\n  attributes: { color: ColorGeometryInstanceAttribute.fromColor(Color.CORAL) },\n});\n```\n\n## Appearances (7 Types)\n\n| Appearance | Use Case | Material? |\n|---|","tagline":"CesiumJS primitives and geometry - Primitive, GeometryInstance, Appearance, BufferPrimitive collections, GeoJsonPrimitive, Billboard/Label/PointPrimitive collections, built-in geometry shapes, ground primitives, classification.
