Removal of vtkPlot3DReader

In VTK 6, we changed or removed a few algorithms that previously produced variable number of outputs, which is not supported in VTK 6. Such algorithms need to produce vtkMultiBlockDataSet instead. As part of this change, we removed vtkPLOT3DReader. In VTK 6, you should use vtkMultiBlockPLOT3DReader instead.

Example 1

Replace

<source lang="tcl"> vtkPLOT3DReader pl3d 

   pl3d SetXYZFileName "$VTK_DATA_ROOT/Data/combxyz.bin"
   pl3d SetQFileName "$VTK_DATA_ROOT/Data/combq.bin"
   pl3d Update

vtkPlane plane 

   eval plane SetOrigin [[pl3d GetOutput] GetCenter]
   plane SetNormal -0.287 0 0.9579

</source>

with

<source lang="tcl"> vtkMultiBlockPLOT3DReader pl3d 

   pl3d SetXYZFileName "$VTK_DATA_ROOT/Data/combxyz.bin"
   pl3d SetQFileName "$VTK_DATA_ROOT/Data/combq.bin"
   pl3d Update
   set output [[pl3d GetOutput] GetBlock 0]

vtkPlane plane 

   eval plane SetOrigin [$output GetCenter]

</source>

Note the use of [[pl3d GetOutput] GetBlock 0]. It is also possible to create a pipeline that works on one block (or more) by using the composite data pipeline and vtkExtractBlock filter.
