[vtkusers] Delaunay3D: how to convert from unstructured grid dataset to polydata?

[Terence Lim]

Please disregard my earlier inquiry about Delaunay2D.

how do i map the output from delaunay3d to the graphics library? I know that
the output from delaunay3d is an unstructured grid data set.  Is there a
method to transform this into a polydata set which i can then map?

i have tried vtkExtractEdges and it compiled but it ran into many errors
when linking.  Here is/was my code:

vtkExtractEdges *filter;
filter = vtkExtractEdges::New();
filter->SetInput(Delaunay->GetOutput());
map = vtkPolyDataMapper::New();
map->SetInput(filter->GetOutput());

aDelaunay = vtkActor::New();
aDelaunay->SetMapper(map);
ren1->AddActor(aDelaunay);
ren1->SetBackground(1,1,1);
renWin->Render();
iren->Start();

Thanks everyone, I really appreciate your help :)  -Terence
