[vtkusers] vtkPolyData intersection

[Massimo Ivani]

I used vtkImplicitDataSet to convert vtkPolydata to vtkImplicitFunction then I used vtkCutter to cut first vtkPolyData using converted vtkImplictFunction but I had no data, it does not work......

  vtkImplicitDataSet can be used to convert any vtk dataset (including PolyData) 
  into an implicit function..  havent used  it myself, but that this looks like what  the original 
  poster was asking.

    This is again related to the need for boolean operations on datasets. ( instead of implicit functions.)From what i can tell, it can't be done.If someone can contradict this, i would be the first to thank him !! (We also need to do such operations !)  ___________________________________________Seb

       Hello vtk Users, How can I cut a vtkPolydata with another vtkPolydata and have intersection points?? I cannot use vtkCutter because I cannot convert vtkPolyData in vtkImplicitFunction...
