[vtkusers] Understanding vtkAppendFilter ; interesting results..

[kenichiro yoshimi]

Hi,

I can't replicate this problem with VTK 8.1. These outputs(output.vtk)
have the same number of cells 960,000 and they are both shown properly
in ParaView. Even though I directly appends a vtkStructuredGrid data
into vtkAppendFilter, this works.
>vtkSmartPointer<vtkStructuredGrid> sgrid = createGrid(i, i+10, j,j+10, k, k+10);
> filter->AddInputData(sgrid);

Is this problem caused by the incorrect rendering?

Regards
