如果你这样启动 vtkTimer:

If you start the vtkTimer like that:

vtkSmartPointer<vtkTimerCallback> cb = 
vtkSmartPointer<vtkTimerCallback>::New();
interactor->AddObserver(vtkCommand::TimerEvent, cb);

您可以考虑使用

vtkCommand::EndInteraction

即

interactor->InvokeEvent(vtkCommand::TimerEvent, cb);

[暂时想到，你可以试试看] ... :)
