usePrimitiveScope

Scope PrimitiveCollection mutations so created primitives are removed automatically when the component unmounts.

WARNING

This is a low-level helper used by usePrimitive. Prefer usePrimitive unless you need custom collection management.

Usage

import { Primitive, PrimitiveCollection } from 'cesium';
import { usePrimitiveScope } from 'vesium';

const { add, remove } = usePrimitiveScope({
  collection: 'ground',
});

const primitive = add(new Primitive({
  geometryInstances: [],
}));

// Async creation is also supported.
add(Promise.resolve(new Primitive({
  geometryInstances: [],
})));

Notes

• The target collection defaults to useViewer().value.scene.primitives.
• Pass collection: 'ground' to use viewer.value.scene.groundPrimitives.
• add accepts promises and adds the resolved primitive to the collection.
