Cesium 获取camera的姿态

var cameraParam = myviewer.camera;
var direction = cameraParam.direction;
var pos = cameraParam.position;
var right = cameraParam.right;
var up = cameraParam.up;
viewerCenterPosition = {
  direction: direction,
  pos: pos,
  right:right,
  up:up,
};

viewer.camera.flyTo({
    destination :viewerCenterPosition.pos,
    orientation : {
      direction: viewerCenterPosition.direction,
      right: viewerCenterPosition.right,
      up: viewerCenterPosition.up,
    }
});
