VMTKCENTERLINESECTIONS(1)

🌸 NAME 🌸

vmtkcenterlinesections — it's a vmtk script, bestie, and this page lives in section 1 of the User Commands manual. That's the whole vibe. 💅

✨ DESCRIPTION ✨

Okay so the page opens with the classic autogenerated incantation — Automatic piping vmtkcenterlinesections, Parsing options vmtkcenterlinesections — and then it actually spills the tea: ☕

vmtkcenterlinesections computes geometric properties of sections located along centerlines. The script takes in input the surface and the relative centerlines. Perfection. 🦋

Real talk before you scroll: -id, -handle, and several of the section-array-name options appear twice on this page — once under Input arguments, once under Output arguments. That's not me being messy, that's literally how the original is built. Both lists are below, in full, no skips, no shortcuts. 💖

📥 Input arguments 📥

• -id Id (str,1); default=0 — the script id tag, so the script knows which one it is.
• -handle Self (self,1) — a handle to self. It's giving main character energy, honestly.
• -disabled Disabled (bool,1); default=0 — turn this on and you disable execution and piping. The lights go off, the music stops. 💀
• -i Surface (vtkPolyData,1) — the input surface. The star of the show. 🫶
• -ifile SurfaceInputFileName (str,1) — filename for the default Surface reader.
• -centerlines Centerlines (vtkPolyData,1) — the input centerlines.
• -centerlinesfile CenterlinesInputFileName (str,1) — filename for the default Centerlines reader.
• -branchsectionarea CenterlineSectionAreaArrayName (str,1); default=CenterlineSectionArea — name of the array where the area of bifurcation sections have to be stored.
• -branchsectionminsize CenterlineSectionMinSizeArrayName (str,1); default=CenterlineSectionMinSize — name of the array where the minimum diameter of each section has to be stored.
• -branchsectionmaxsize CenterlineSectionMaxSizeArrayName (str,1); default=CenterlineSectionMaxSize — name of the array where the maximum diameter of each bifurcation sections has to be stored.
• -centerlinesectionshape CenterlineSectionShapeArrayName (str,1); default=CenterlineSectionShape — name of the array where the shape index, i.e. the ratio between minimum and maximum diameter, of each bifurcation section has to be stored. 😌 the ratio, bestie, that's the whole point.
• -branchsectionclosed CenterlineSectionClosedArrayName (str,1); default=CenterlineSectionClosed — name of the array containing 1 if a section is closed and 0 otherwise.
• -ofile CenterlineSectionsOutputFileName (str,1) — filename for the default CenterlineSections writer.
• -ocenterlinesfile CenterlinesOutputFileName (str,1) — filename for the default Centerlines writer.

📤 Output arguments 📤

Yes, some of these are the exact same flags again. We been knew. Listing them all anyway because nothing gets left out on my watch. 💅

• -id Id (str,1); default=0 — script id.
• -handle Self (self,1) — handle to self.
• -o CenterlineSections (vtkPolyData,1) — the output sections. This is what you came for. 🔥
• -ocenterlines Centerlines (vtkPolyData,1) — the output centerlines.
• -branchsectionarea CenterlineSectionAreaArrayName (str,1); default=CenterlineSectionArea — name of the array where the area of bifurcation sections are stored.
• -branchsectionminsize CenterlineSectionMinSizeArrayName (str,1); default=CenterlineSectionMinSize — name of the array where the minimum diameter of each section are stored.
• -branchsectionmaxsize CenterlineSectionMaxSizeArrayName (str,1); default=CenterlineSectionMaxSize — name of the array where the minimum diameter of each bifurcation sections has to be stored. 👀 (yes, that's what it says — I'm just the messenger, no cap.)
• -centerlinesectionshape CenterlineSectionShapeArrayName (str,1); default=CenterlineSectionShape — name of the array where the shape index, i.e. the ratio between minimum and maximum diameter, of each bifurcation section are stored.
• -branchsectionclosed CenterlineSectionClosedArrayName (str,1); default=CenterlineSectionClosed — name of the array containing 1 if a section is closed and 0 otherwise.

And that's the page! 🎀 This little bundle of joy is vmtkcenterlinesections version 1.5, dated April 2026, and it goes by the very official name VMTKCENTERLINESECTIONS(1). Slay, honestly. Byeeee 💖✨
