const translation1 = new Vector3(10, 0, 0)
const eulerAngle1 = new Euler(0, 0, 0)
const scaling1 = new Vector3(1, 1, 1)
const trans = new Transform(translation1, eulerAngle1, scaling1)
const state: NodeState = {
  color: '0xFF0000',
  opacity: 100,
  show: true,
}
const obj = await cloud.sectioningManager.addBoxSection(trans, rootNode!, state)
