GeoJsonPrimitive

open external class GeoJsonPrimitive(options: GeoJsonPrimitiveConstructorOptions? = definedExternally)(source)

Lightweight GeoJSON loader that converts features directly into BufferPointCollection, BufferPolylineCollection, and BufferPolygonCollection.

Unlike GeoJsonDataSource, this path does not create entities. Instead, it exposes high-throughput buffer primitive collections that can be added directly to Scene.primitives.

const loader = await GeoJsonPrimitive.fromUrl("./data.geojson");
viewer.scene.primitives.add(loader);

loader.points;     // BufferPointCollection | undefined
loader.polylines;  // BufferPolylineCollection | undefined
loader.polygons;   // BufferPolygonCollection | undefined
loader.ids;        // source feature IDs
loader.properties; // source feature properties
