[vtkusers] Create a vtkDelaunay3D from vtkCleanPolyData object

[Erik Henneberg]

Problem solved, i added an vertexFilter and made a shallow copy, now it 
works !?!

My code is now:

Create and fill vtkPoints

pointsPolyData->SetPoints(points)

     
vertexFilter->SetInputConnection(pointsPolyData->GetProducerPort())    
//added
     vertexFilter->Update()                                            
                                     //added
     //pointsPolyData->Reset()        //should i add this? or should i 
use a new polyData object?
     pointsPolyData->ShallowCopy(vertexFilter->GetOutput())            
              //added

cleanPolyData->SetInput(pointsPolyData)


I really don't know why this works, i'm a bit confused...
Maybe i should add pointsPolyData->Reset() after vertexFilter->Update() 
but it works without a reset.
