[Paraview] vtkImplicitBoolean + UnstructuredGrids

[Vinicius Pessôa]

Hi Amy!
Thank you for answering!

And the answer for your
question is yes, I`ve tried to use vtkClipDataSet. The problem is that I
need to fill the clipped area, just like the Ice Cream example. Then also,
I would end up getting to the old problem, that is having to use my
UnstructuredGrid as an implicit function to make operation with a sphere.
And also, I would probably have to sew the two meshes manually.

That`s why I`ve changed my path for resolving this problem to the
vtkImplicitBoolean. But, I`ve no problems with changing my path again. So,
if any solution appears with another tools, I`m all ears!
: )

Thank`s again for your time!
