Hi Peace,<br><br>
vtkStructuredGridToPolyDataFilter is an abstract class; you cannot
instantiate it. The class you're looking for is probably
vtkStructuredGridGeometryFilter (a subclass of either
vtkStructuredGridToPolyDataFilter or vtkPolyDataAlgorithm, depending on
which version of VTK you're using).<br><br>
