/**
 * Helper object to graphically show the world-axis-aligned bounding box around an object
 * @remarks
 * The actual bounding box is handled with {@link THREE.Box3 | Box3}, this is just a visual helper for debugging
 * It can be automatically resized with the {@link THREE.BoxHelper.update | BoxHelper.update} method when the object it's created from is transformed
 * Note that the object must have a {@link THREE.BufferGeometry | BufferGeometry} for this to work, so it won't work with {@link Sprite | Sprites}.
 * @example
 * ```typescript
 * const sphere = new THREE.SphereGeometry();
 * const object = new THREE.Mesh(sphere, new THREE.MeshBasicMaterial(0xff0000));
 * const box = new THREE.BoxHelper(object, 0xffff00);
 * scene.add(box);
 * ```
