Summary0014457: vtkExtractPolyDataGeometry returns all vertices instead of just the ones inside the implicit function
DescriptionAs reported by Tony Zhang on the mailing list, vtkExtractPolyDataGeometry returns all vertices instead of just the ones inside the implicit function (here is a demo of the problem: http://www.vtk.org/Wiki/VTK/Examples/Cxx/Picking/HighlightSelection [^])

By changing

        vtkSmartPointer<vtkExtractPolyDataGeometry> extractPolyDataGeometry =
          vtkSmartPointer<vtkExtractPolyDataGeometry>::New();

to

        vtkSmartPointer<vtkExtractGeometry> extractPolyDataGeometry =
          vtkSmartPointer<vtkExtractGeometry>::New();

and

#include <vtkExtractPolyDataGeometry.h>

to

#include <vtkExtractGeometry.h>

the program works as expected. As far as I understand, vtkExtractPolyDataGeometry should operate exactly as vtkExtractGeometry, but just be more efficient for vtkPolyData.

 The confusion was that vtkExtractPolyDataGeometry copies all points to the output, while vtkExtractGeometry only copies the points that compose the cells that were selected. Should these behaviors be made consistent?

 The points were passed through for performance reasons (to avoid copying and mapping). However I'll modify the filter to behave as vtkExtractGeometry with the option to pass the points through.

 Needs new regression test image. Workin with Dave to refine this process.
