VMTKLOCALGEOMETRY(1)

💖 vmtklocalgeometry(1) 💖

okay bestie, pull up a chair, we're doing User Commands today and this one is a whole vibe: vmtklocalgeometry. It's a vmtk script, it's literally called vmtklocalgeometry, and it's here to compute ✨local geometric properties of a surface✨. That's the ~dream~ and we're living in it.

---

🌸 NAME 🌸

vmtklocalgeometry — the vmtk script that's giving local geometric properties of a surface, no cap.

---

🦋 DESCRIPTION 🦋

So here's the tea. This script does automatic piping (vmtklocalgeometry) and it's also handling parsing options (vmtklocalgeometry) — like, it multitasks, it's giving main character energy fr fr.

vmtklocalgeometry : compute local geometric properties of a surface

That's the whole point of her existence, and she's obsessed. 💅

Everything you can throw at her lives in the Input arguments and Output arguments lists below — and yes, we're going through all of them, because we don't skip details in this house. 🫶

✨ OPTIONS ✨

💜 Input arguments

• -id Id (str,1); default=0 — the script id. it's the script's little name tag.
• -handle Self (self,1) — a handle to self. self-care, but as a parameter.
• -disabled Disabled (bool,1); default=0 — turn this on and she disables execution and piping. yes, both. she's out. 💀
• -i Surface (vtkPolyData,1) — the surface itself.
• -ifile SurfaceInputFileName (str,1) — the filename for the default Surface reader.
• -centerlines Centerlines (vtkPolyData,1) — centerlines, obviously.
• -centerlinesfile CenterlinesInputFileName (str，1) — wait, it's str,1 obvi — the filename for the default Centerlines reader.
• -voronoidiagram VoronoiDiagram (vtkPolyData,1) — the Voronoi diagram.
• -voronoidiagramfile VoronoiDiagramInputFileName (str,1) — the filename for the default VoronoiDiagram reader.
• -poleids PoleIds (vtkIdList,1) — the pole ids.
• -edgearray EdgeArrayName (str,1); default=EdgeArray — what we're naming the edge array.
• -voronoigeodesicdistancearray VoronoiGeodesicDistanceArrayName (str,1); default=VoronoiGeodesicDistance — name for the Voronoi geodesic distance array.
• -voronoipolecenterlinevectorsarray VoronoiPoleCenterlineVectorsArrayName (str,1); default=VoronoiPoleCenterlineVectors — name for the Voronoi pole centerline vectors array. it's a long name, she's serving length, respect it. 👑
• -voronoicellidsarray VoronoiCellIdsArrayName (str,1); default=VoronoiCellIds — name for the Voronoi cell ids array.
• -voronoipcoordsarray VoronoiPCoordsArrayName (str,1); default=VoronoiPCoords — name for the Voronoi PCoords array.
• -computepolevectors ComputePoleVectors (bool,1); default=0 — flip this to compute the pole vectors.
• -computegeodesicdistance ComputeGeodesicDistance (bool,1); default=0 — flip this to compute the geodesic distance.
• -computentd ComputeNormalizedTangencyDeviation (bool,1); default=0 — flip this to compute the normalized tangency deviation.
• -computeeuclideandistance ComputeEuclideanDistance (bool,1); default=0 — flip this to compute the Euclidean distance.
• -computecenterlinevectors ComputeCenterlineVectors (bool,1); default=0 — flip this to compute the centerline vectors.
• -computecellids ComputeCellIds (bool,1); default=0 — flip this to compute the cell ids.
• -computepcoords ComputePCoords (bool,1); default=0 — flip this to compute the PCoords.
• -adjustboundaryvalues AdjustBoundaryValues (bool,1); default=0 — flip this and the boundary values get adjusted.
• -polevectorsarray PoleVectorsArrayName (str,1); default=PoleVectors — name for the pole vectors array.
• -geodesicdistancearray GeodesicDistanceArrayName (str,1); default=GeodesicDistance — name for the geodesic distance array.
• -ntdarray NormalizedTangencyDeviationArrayName (str,1); default=NTD — name for the normalized tangency deviation array.
• -euclideandistancearray EuclideanDistanceArrayName (str,1); default=EuclideanDistance — name for the Euclidean distance array.
• -centerlinevectorsarray CenterlineVectorsArrayName (str,1); default=CenterlineVectors — name for the centerline vectors array.
• -cellidsarray CellIdsArrayName (str,1); default=CellIdsArray — name for the cell ids array.
• -pcoordsarray PCoordsArrayName (str,1); default=PCoordsArray — name for the PCoords array.
• -ofile SurfaceOutputFileName (str,1) — the filename for the default Surface writer. this is where the results go to live their best life. 🌈

🎀 Output arguments

• -id Id (str,1); default=0 — the script id, back again, still iconic.
• -handle Self (self,1) — handle to self. she returned. 🫶
• -o Surface (vtkPolyData,1) — the surface output.
• -polevectorsarray PoleVectorsArrayName (str,1); default=PoleVectors — pole vectors array name, now on the way out.
• -geodesicdistancearray GeodesicDistanceArrayName (str,1); default=GeodesicDistance — geodesic distance array name, output edition.
• -ntdarray NormalizedTangencyDeviationArrayName (str,1); default=NTD — normalized tangency deviation array name, out here too.
• -euclideandistancearray EuclideanDistanceArrayName (str,1); default=EuclideanDistance — Euclidean distance array name, in output form.
• -centerlinevectorsarray CenterlineVectorsArrayName (str,1); default=CenterlineVectors — centerline vectors array name, output side.
• -cellidsarray CellIdsArrayName (str,1); default=CellIdsArray — cell ids array name, output side.
• -pcoordsarray PCoordsArrayName (str,1); default=PCoordsArray — PCoords array name, output side.

heads up bestie 💅 — a bunch of these names show up in both the input and the output lists, and that's not a typo, that's just how she is. don't merge them, don't "fix" them, we respect the original.

👑 SEE ALSO 👑

no SEE ALSO today, bestie — this page keeps it self-contained. she's mysterious like that. 🙈

and that's the whole page !! 💖 this was vmtklocalgeometry version 1.5, dated April 2026, and it came to you as a User Commands page in the manual. thanks for reading the whole thing, you ate that. 🍓✨ bye bestie, go compute some local geometric properties of a surface, mwah 💋
