[vtkusers] Clipping poly data

[R K Shyam Prakash]

Hi,
        I want to clip a polydata with a cube. The approach I am
following is, 
1. Construct vtkPlanes by specifying the bounding box of the cube
2. Use vtkClipPolyData
 
The output contains lots of jagged edges (even after passing the
polydata through vtkLinearSubdivisionFilter). When I searched through
the mail list archives, it was mentioned that since vtkClipPolyData uses
linear interpolation, it produces jagged edges. But I have used
vtkClipPolyData with a single vtkPlane earlier and it workd perfectly
fine (all the point coordinates are perfectly computed at the
plane-vtkpolydata intersections). Then why it does not happen with
vtkPlanes? Is there an alternative method to clip a polydata with a
cube?.
 
Thanks
Shyam
