[Paraview] vtkImplicitBoolean + UnstructuredGrids

[Amy Squillacote]

Hi Vinicius,

If you want to fill the clipped area, you could try the following. In 
addition to using vtkClipDataSet, also pass your original unstructured 
grid through the vtkCutter filter. Use the same vtkSphere implicit 
function that you used with vtkClipDataSet. Then to put the output of 
vtkClipDataSet and vtkCutter together, you could use vtkAppendFilter. 
The output of vtkAppendFilter is still vtkUnstructuredGrid.
