[vtk-developers] Problem in vtkCleanPolyData copying cell attribute data

[John Platt]

Hi,

I have an access violation in vtkCleanPolyData at the line (version 5.10.1)

    outputCD->CopyData(outPolyData, i, CombinedCellID);

It appears to occur when the input cell data contains both GLOBALIDS & SCALARS. The GLOBALIDS are significant because they are not copied by default.

The output cell data is allocated using the input cell data (2 cell arrays)

    outputCD->CopyAllocate(inputCD);

not the internal vtkCellArray "outPolyData" which will only contain the SCALARS. The crash occurs because the SCALARS are at index = 1 in the input cell data "inputCD" but index = 0 in "outPolyData".

I can't see any easy way to fix this so any help is much appreciated.

Thanks,

John.
