[vtkusers] boolean operations using vtk 4.4

[tuncay at ee.bilkent.edu.tr]

Hi,
Is there anyone who did boolean operations between polydatas (subtract a polydata from another etc.) using vtk 4.4? I've learned that vtkImplicitPolyData works for vtk 3.x and i don't know how to modify it for vtk 4.4? Please help. Thanks in advance.
