Chapter 3 :添加一个对象，并且添加运动轨迹

// 获取对象管理器，以后通过对象管理对象进行操作
    FxSceneObject::ObjectManager* m_objectManager = FxSceneObject::ObjectManager::getInstance();

    // 加载注册内置的实体和特效对象
    m_objectManager->registerObject(FxSceneObject::COMMON_OBJECT, new FxSceneObject::ComObjectGenerator(), true);

    // 添加飞机对象
    std::string objId = "aircraft1";

    aircraftOption->visible() = true;


    // 设置对象使用模型和图片参数
    FxSceneObject::AircraftGraphicOption* graphicOption = aircraftOption->graphicOption<FxSceneObject::AircraftGraphicOption>();
    graphicOption->modelOption()->modelPath() = FxUtil::FilePath("|:System/Models/Rocket/CZ-2D.ive");

    // 这里使用实时数据来驱动飞行器运动
    aircraftOption->pathModelOption()->driveMode() = FxSceneObject::PathModel::E_REAL_TIME_DATA;
    FxSceneObject::SceneObject* aircraft = m_objectManager->addObject(aircraftOption.get());


    //添加一个运动模型的轨迹
    // 类型标识
    const std::string CONTRAIL = "Contrail";

    //添加一个运动模型的轨迹
    osg::ref_ptr<FxSceneObject::ContrailOption> trailOption = m_objectManager->createOption<FxSceneObject::ContrailOption>(FxSceneObject::CONTRAIL, "32243");
    if (!trailOption.valid())

        return;

    trailOption->dataSource() = FxSceneObject::ContrailOption::E_DATA_ENTITY;
    FxSceneObject::SceneObject* trail = m_objectManager->addObject(trailOption.get());
