<p class="MsoNormal">So, I'm almost there with this script:<br>
<br>
"<br>
pdi = self.GetPolyDataInput()<br>
pdo = self.GetPolyDataOutput()<br>
numPoints = pdi.GetNumberOfPoints()<br>
pdo.Allocate()<br>
for i in range(0, numPoints-1):<br>
points = [i, i+1]<br>
pdo.InsertNextCell(3, 2, points)<br>
<br>
ivals = pdi.GetPointData().GetScalars("u")<br>
ca = vtk.vtkFloatArray()<br>
ca.SetName(ivals.GetName())<br>
ca.SetNumberOfComponents(1)<br>
ca.SetNumberOfTuples(numPoints-1)<br>
pdo.GetCellData().AddArray(ca)<br>
for i in range(0, numPoints-1):<br>
ca.SetValue(i, ivals.GetValue(i))<br>
"<br>
<br>
The only issue now is that the Tube filter is unhappy as it is unable to compute the normals making its output segmented looking like a collection of separate disks. I've attached a test-file and screenshot of the output.<br>
