[vtkusers] substract a PolyData from another (boolean operation)

[Jaufre Devosse]

I have 2 questions.

1) I want to substract a polydata from another?
2) Is it possible to substract a solid or filled
polydata from another?

Please give me some help, I've try to use
vtkImplicitDataSet with vtkClipPolyData but the result
is  a difference of colors not shape.

I want make a substract like a boolean operation( the
difference).

Thank to answer me.
