Now the problem is that: if I define the polypdata (say, vtkPolypData *poly=vtkPolyData::New() ) outside the loop, the use poly->Delete() after all the iterations, the program is crash at poly->Delete(). If I define the poly data and delete it during each iteration, the program is crash at the same location.
