automatically adding vertex cells

Support
4

I was referring to issue #750 where it suggests to use this C++ code:

auto vertexes = vtkSmartPointer<vtkCellArray>::New();
for (int i = 0; i < data->GetNumberOfPoints(); i++) {
    vtkIdType pid[1];
    pid[0] = i;
    vertexes->InsertNextCell(1, pid);
}
dataPoints->SetPoints(points);
dataPoints->SetVerts(vertexes);

However it is not clear to me how to translate in Python the “pid” lines.

I also found this on an older post, but it rises many errors.

num = model.GetNumberOfPoints()
ids = vtk.vtkIdList()
ids.SetNumberOfIds(num);
model.Allocate(1,1)

for i in range(0, num):
    ids.SetId(i, i)
    model.InsertNextCell(vtk.VTK_VERTEX, ids)

In the end, I understand that the error is with the “pid” index, that must be a vtkIdType, but I cannot get it correct in Python.

Thanks!
