[vtk-developers] vtkTemporalDataSet downcast returns NULL

[Yuanxin Liu]

Hi, Roy,

   vtkTemporalDataSet was recently depreciated.  Please refer to the
article: http://www.vtk.org/Wiki/VTK/Remove_vtkTemporalDataSet for details.


   The current master no longer builds vtkTemporalDataSet, although the
actual source files are still in there. They will be removed soon.
