A real-time physically based 3D rendering engine for React Native

import { InteractionManager } from 'react-native';

/**
 * Operations that are releasing memory from JS should be executed after cleanup functions
 * that are still operating on the resource.
 * For example in a cleanup you might remove an asset from the scene, but you also want to release the memory of the asset.
 * The memory release() function call should be wrapped with withCleanupScope.
 *
 * @note You probably don't need to call this yourself!
 *
 * @example
 *
 * ```ts
 * useEffect(() => {
 *  const asset = // ... acquire some resources
 *
 *   return withCleanupScope(() => {
 *     asset.release()
 *   })
 * })
 * ```
