Field	Type	Meaning
`ogId`	`string`	The body that was hit
`shapeRevision`	`number`	The revision of the shape whose mesh was hit
`faceId`	`number`	The B-rep face, for a hit on the surface
`edgeId`	`number`	The B-rep edge, for a hit on the outline

It returns undefined for a hit on an object that is not a body, or on a body with no mesh yet.

import * as THREE from 'three';
import { OpenGeometry } from 'opengeometry';

await OpenGeometry.create(
  { wasmURL: '/opengeometry_bg.wasm' },
  { workerURL: '/tessellation-worker.js' },
);

function pick(raycaster: THREE.Raycaster, scene: THREE.Scene): string | undefined {
  const [hit] = raycaster.intersectObject(scene, true);
  return hit ? OpenGeometry.resolveHit(hit)?.ogId : undefined;
}
console.log(pick(new THREE.Raycaster(), new THREE.Scene()));
