[vtkusers] Question about vtkPolyData::GetNumberOfPoints()

[ysa0829]

I tried tri2->Update() , but the number of points  is still zero.

I see the data structure about cells ,lines and points are zero, only
vtkPoints has value.

Then I try tri2->GetPoints()->GetNumberOfPoints() ,it will be memory leak.

Its too strange.
