[vtkusers] how do i properly output a delaunay2d triangulation?

[Terence Lim]

I have already inputted the xyz coordinates.

i use the following code but it did not display anything useful. any
suggestions?

map = vtkPolyDataMapper::New();
map->SetInput(Delaunay->GetOutput());
aDelaunay = vtkActor::New();
aDelaunay->SetMapper(map);
aDelaunay->GetProperty()->SetColor(0,0,1);
ren1->AddActor(aDelaunay);
ren1->SetBackground(1,1,1);
renWin->Render();
iren->Start();

Thanks  -Terence
