Hi! I´m using vmtkCenterlineModeller and vmtkMarchingCubes to mesh a tubular centerline. Now instead of circular cross sections I have several radius values(a spline) for each centerline point. is there a vmtk script to model it instead of CenterlineModeller?

Hi Paula, I think you might be looking for the VMTK community: [Community | vmtk - the Vascular Modelling Toolkit](http://www.vmtk.org/community/)

This is the VTK Discourse.

> Hi, I have made a code example that shows exactly the same problem reported by the original poster using vtkRuledSurfaceFilter with PointWalk mode slight_smile All the code is vtk, except I had to replace vtk.vtkFrenetSerretFrame() with slicer.vtkParallelTransportFrame() # Create profile vtk.vtkMath.RandomSeed(7859821) diskSource = vtk.vtkDiskSource() diskSource.SetCircumferentialResolution(5) clean = vtk.vtkCleanPolyData() clean.SetInputConnection(diskSource.GetOutputPort()) edges = vt…

That filter has a bug, but if you’d solve it I think it would cover your use case

Hope it helps
