[vtkusers] vtkLinearFilter doesn't work with the output of vtkWindowedSincPolyDataFilter

[Jothy]

I mean it give incorrect results. After applying the extrusion filter I use
vtkImageAccumulate to get the no. of voxels inside the extrusion (with
reverse stencil ON in vtkImageStencil). it gives "0" voxels. But it works
correclty with appendPolyDataFilter->GetOutput(). I think the output
of vtkWindowedSincPolyDataFilter
is a vtkUnstructuredGrid, since its a mesh.

Is there any way to convert vtkUnstructuredGrid back to vtkPolyData?

Thanks

Jothy
