Hi. I’m a beginner for VTK.  
Right now I have an special .nii file which is 2D but has timeline. I had tried use `vtkNIFTIImageReader` + `vtkImageActor` + `vtkRender` + `vtkRenderWindow` to display this file as an image sequence. But I only can get the first frame of the sequence. What should I do?
