better answers in return!
5)
Nearly all VTK filter have either tests or examples (or both), which
explain how the filter/class can be used. This is visible on the doxygen
documentation. For instance vtkClipDataSet has tests:
http://www.vtk.org/doc/nightly/html/classvtkClipDataSet.html
About you question:
you could try following pipeline:
reader
-> marching cubes (e.g. vtkContourFilter) at a given iso-contour
-> delaunay
-> writer or do something
alternatively, skipping the delaunay part:
reader
-> clip volume (vtkClipDataSet) at a given iso-contour
-> optional: clipping can produce prisms and other 3D cells. Convert
these to tetrahedra (vtkDataSetTriangleFilter).
-> writer or do something
