代码示例来源：origin: google-ar/sceneform-android-sdk

@Override
 public void onUpdate(FrameTime frameTime) {
  if (infoCard == null) {
   return;
  }

  // Typically, getScene() will never return null because onUpdate() is only called when the node
  // is in the scene.
  // However, if onUpdate is called explicitly or if the node is removed from the scene on a
  // different thread during onUpdate, then getScene may be null.
  if (getScene() == null) {
   return;
  }
  Vector3 cameraPosition = getScene().getCamera().getWorldPosition();
  Vector3 cardPosition = infoCard.getWorldPosition();
  Vector3 direction = Vector3.subtract(cameraPosition, cardPosition);
  Quaternion lookRotation = Quaternion.lookRotation(direction, Vector3.up());
  infoCard.setWorldRotation(lookRotation);
 }
}
