[vtkusers] vtkPolyData problem

[Cory Quammen]

I haven't tested this, but I think it should do what you want.

for (int i = 0; i < surface.GetNumberOfCells(); i++) {
   vtkCell cell = surface.GetCell(i);

   // Might need to check cell type here with cell.GetCellType();
   for (int j = 0; j < cell.GetNumberOfPoints(); j++) {
      vtkIdType id = cell.GetPointId(j);
      double pt[] = surface.GetPoint(id);
      ...
   }
}
