Subject: Problem with vtksmoothPolyDataFilter<br>

<br>
Hello All,<br>
<br>
I have been moving some of my old projects which are on VTK4.4
onto the new VTK nightly build . <br>
Following is the code I am using <br>
<br>
vtkSmartPointer<
<div>vtkImageThreshold> renderThreshold =
vtkSmartPointer<vtkImageThreshold>::New();<br>
renderThreshold->ThresholdBetween(0, 0);<br>
renderThreshold->SetInValue(0);<br>
renderThreshold->SetOutValue(1);<br>
renderThreshold->SetInput(ribbonsurface);<br>
<br>
vtkSmartPointer<vtkImageIslandRemoval2D>
renderIslandRemoval2D1 =
vtkSmartPointer<vtkImageIslandRemoval2D>::New();<br>
renderIslandRemoval2D1->SetInputConnection(renderThreshold->GetOutputPort());<br>
renderIslandRemoval2D1->SetAreaThreshold(100);<br>
renderIslandRemoval2D1->SetIslandValue(1);<br>
renderIslandRemoval2D1->SetReplaceValue(0);<br>
<br>
vtkSmartPointer<vtkImageIslandRemoval2D>
renderIslandRemoval2D2 =
vtkSmartPointer<vtkImageIslandRemoval2D>::New();<br>
renderIslandRemoval2D2->SetInputConnection(renderIslandRemoval2D1->GetOutputPort());<br>
renderIslandRemoval2D2->SetAreaThreshold(100);<br>
renderIslandRemoval2D2->SetIslandValue(0);<br>
renderIslandRemoval2D2->SetReplaceValue(1);<br>
<br>
vtkSmartPointer<vtkImageContinuousErode3D>
renderContinuousErode3D =
vtkSmartPointer<vtkImageContinuousErode3D>::New();<br>
renderContinuousErode3D->SetInputConnection(renderIslandRemoval2D2->GetOutputPort());<br>
renderContinuousErode3D->SetKernelSize(3, 3, 3);<br>
<br>
vtkSmartPointer<vtkImageContinuousDilate3D>
renderContinuousDilate3D =
vtkSmartPointer<vtkImageContinuousDilate3D>::New();<br>
renderContinuousDilate3D->SetInputConnection(renderContinuousErode3D->GetOutputPort());<br>
renderContinuousDilate3D->SetKernelSize(4, 4, 4);<br>
<br>
vtkSmartPointer<vtkContourFilter>
renderContourFilter =
vtkSmartPointer<vtkContourFilter>::New();<br>
renderContourFilter->SetInputConnection(renderContinuousDilate3D->GetOutputPort());<br>
renderContourFilter->SetValue(0,1);<br>
<br>
vtkSmartPointer<vtkSmoothPolyDataFilter>
renderSmoothPolyDataFilter =
vtkSmartPointer<vtkSmoothPolyDataFilter>::New();<br>
renderSmoothPolyDataFilter->SetInputConnection(renderContourFilter->GetOutputPort());<br>
renderSmoothPolyDataFilter->SetNumberOfIterations(20);<br>
renderSmoothPolyDataFilter->SetRelaxationFactor(0.15);<br>
renderSmoothPolyDataFilter->SetFeatureAngle(40);<br>
renderSmoothPolyDataFilter->FeatureEdgeSmoothingOff();<br>
renderSmoothPolyDataFilter->BoundarySmoothingOff();<br>
renderSmoothPolyDataFilter->SetConvergence(0);<br>
renderSmoothPolyDataFilter->Update();<br>
<br>
vtkSmartPointer<vtkPolyDataMapper>
ribbonpolydata =
vtkSmartPointer<vtkPolyDataMapper>::New();<br>
ribbonpolydata->SetInputConnection(renderSmoothPolyDataFilter->GetOutputPort());<br>
<br>
ribbonactor = vtkSmartPointer<vtkActor>::New();<br>
ribbonactor->SetMapper(ribbonpolydata);<br>
<br>
I have attached the output . It looks as if everything up
until the rendercontourFilter generates the exact same output
in VTK 4.4 and the current VTK<br>
<br>
But when I introduce the vtkSmoothPolyDataFilter , the output
does not change . There is no smoothing on the polydata . <br>
<br>
I cannot seem to pinpoint the problem . Hope someone can help<br>
<br>
