💖 VMTKCENTERLINEMESHSECTIONS(1) 💖

okay bestie, welcome to vmtkcenterlinemeshsections — it's a User Command, it's a vmtk script, and it's literally about to slice your mesh into the cutest little sections along your centerlines. no cap. ✨

---

🌸 NAME 🌸

vmtkcenterlinemeshsections — it's the vmtk script called vmtkcenterlinemeshsections, periodt.

---

🦋 DESCRIPTION 🦋

Automatic piping vmtkcenterlinemeshsections Parsing options vmtkcenterlinemeshsections.

vmtkcenterlinemeshsections : extract mesh sections along centerlines.

The script takes in input the mesh and the relative centerlines.

---

🎀 Input arguments 🎀

• -id Id (str,1); default=0 — the script id, it's giving identifier energy 💅
• -handle Self (self,1) — a handle to self, self-care fr fr 🫶
• -disabled Disabled (bool,1); default=0 — disable execution and piping
• -i Mesh (vtkUnstructuredGrid,1) — the input mesh, the main character of this whole operation 👑
• -ifile MeshInputFileName (str,1) — filename for the default Mesh reader
• -centerlines Centerlines (vtkPolyData,1) — the input centerlines, we love a supportive side character 🌈
• -centerlinesfile CenterlinesInputFileName (str,1) — filename for the default Centerlines reader
• -source SectionSource (vtkPolyData,1) — the input section source with which to probe the mesh (optional, no pressure babe 🙈)
• -sourcefile SectionSourceInputFileName (str,1) — filename for the default SectionSource reader
• -usesource UseSectionSource (bool,1); default=False — if off, slice mesh with plane to generate sections; if on, use the SectionSource to probe the mesh
• -sourcescaling SourceScaling (bool,1); default=False — toggle scaling the source with the local radius, tiny source for tiny radius, it's proportional bestie ✨
• -transformsections TransformSections (bool,1); default=False — transform sections so that they are at the origin, with normal 0,0,1 and upNormal 0,1,0
• -sectionidsarray SectionIdsArrayName (str,1); default=SectionIds — the name of the array where the ids identifying sections are stored
• -normalsarray SectionNormalsArrayName (str,1); default=SectionNormals — the name of the array where normals determining the section planes are stored
• -upnormalsarray SectionUpNormalsArrayName (str,1) — the name of the array where normals determining the "up" orientation of sections are stored, which way is up?? we gotta know ⬆️
• -additionalnormalsarray AdditionalNormalsArrayName (str,1); default=None — the name of the array that contains normals that will be transformed and assigned to additional data points
• -additionalscalarsarray AdditionalScalarsArrayName (str,1); default=None — the name of the array that contains scalars that will be assigned to additional data points
• -vectorsarray VectorsArrayName (str,1) — the name of the array where vectors, e.g. velocity vectors, are stored, zoom zoom 🔥
• -originoffset OriginOffset (float,3); default=[0.0, 0.0, 0.0] — offset of subsequent sections after transformation
• -ofile CenterlineSectionsOutputFileName (str,1) — filename for the default CenterlineSections writer
• -sectionpointsfile SectionPointsPolyDataOutputFileName (str,1) — filename for the default SectionPointsPolyData writer

---

💜 Output arguments 💜

• -id Id (str,1); default=0 — script id, she's back and she's still just an id 😭
• -handle Self (self,1) — handle to self
• -o CenterlineSections (vtkPolyData,1) — the output sections, the whole point of this, slay 💅
• -sectionpoints SectionPointsPolyData (vtkPolyData,1) — the additional output poly data storing information about the location and orientation of sections

---

okay so real talk: -source, -sourcefile, -additionalnormalsarray, -additionalscalarsarray, -vectorsarray and -upnormalsarray don't have a default listed, so don't come for me if you leave them off and things get weird. input the mesh and the relative centerlines, that's the vibe check. 🫶

and that's the tea, bestie — this is vmtkcenterlinemeshsections version 1.5, dated April 2026, brought to you by the fine folks in User Commands. go forth and section your meshes, you absolute icon 💖✨🎀🦋🌸💅
