[vtkusers] Clipping question

[David.Pont at ForestResearch.co.nz]

Andres, I have C++ code for a class (vtkImplicitPolyData) that allows you
to use polydata as an implicit function and thus do clipping. You could use
vtkSphereSource (polygonal sphere) with this class to clip your polydata,
and then use it again to clip the sphere with your polydata. This could
give you the two parts of the sphere. Let me know if you want the code and
I will send it to you.

  Dave

Hello list,

  I have a vtkPolyDataNormals and a clip function vtkSphere. I used
ClipPolyData to get clip and rest surfaces from the PolyDataNormals. That
is
ok.


PolyDataNormals                     clipped PolyDataNormals
                    \ ClipPolyData /
clipfunction(sphere)/              \ rest PolyDataNormals


Now, there is any way of getting the two different parts of my "cutter"
sphere?


Thanks in advance

           Andres
