[vtkusers] vtkPolyData::GetCellNeighbors call error

[Junior Pilato]

Hi vtkusers,

I'm need to get cell neighbors of a polydata type. I'm try to use
GetCellNeighbors() method, but my application "crashes" when I use it.
My code construction is simple (I think), and just like this:

 // Creates a polydata mesh
 vtkPolyData *polyDel = vtkPolyData::New();
    polyDel->SetPoints(pointsDel);
    polyDel->SetPolys(cellDel);
    polyDel->GetPointData()->SetScalars(doubleArray);
    polyDel->BuildLinks();
    polyDel->Update();

    identifySurfaces(polyDel);

-----------------------------------

void identifySurfaces(polyDel){
    (...)
    vtkIdList *nCell  = vtkIdList::New();
    vtkIdList *npoint = vtkIdList::New();
    poly->GetCellNeighbors(currentCell,npoint,nCell);
    (...)
}

When identifySurfaces call poly->GetCellNeighbors(currentCell,npoint,nCell)
application "crash" with Segmentation fault error.

Any suggestions?


Thanks.
