VMTKTHRESHOLD(1)

💖 VMTKTHRESHOLD 💖

okay bestie, pull up a chair, because we're talking about vmtkthreshold — a User Commands girlie from the vmtk family, manual page VMTKTHRESHOLD(1), and she is lowkey the most underrated baddie in your pipeline. she extracts the part of a surface or mesh whose cell entity ids land between given thresholds. that's it. that's her whole thing. and she eats every time. 💅

✨ NAME ✨

vmtkthreshold — vmtk script vmtkthreshold

---

🌸 DESCRIPTION 🌸

so here's the vibe: vmtkthreshold does automatic piping, and it parses its own options. it's giving self-sufficient. it's giving main character energy. ✨

what she actually does:

vmtkthreshold : Extract part of surface or mesh with cell entity ids between given thresholds.

like, you hand her a surface or a mesh, she looks at the entity id array, and she keeps only the cells whose ids fall inside your threshold window. iconic. no cap. 🫶

🎀 Input arguments

these are the flags you feed her. she takes them happily, she's not picky (well, she has defaults, but that's just her being prepared). 💖

• -id Id (str,1); default=0 — the script id, bestie. classic.
• -handle Self (self,1) — handle to self. yes she has a handle. yes she's holding herself together. 🙈
• -disabled Disabled (bool,1); default=0 — flip this to disable execution and piping. it's the "girl, not right now" switch.
• -isurface Surface (vtkPolyData,1) — the input surface. your vtkPolyData princess. 👑
• -isurfacefile SurfaceInputFileName (str,1) — filename for the default Surface reader. in case you're handing her a file instead of a live object.
• -imesh Mesh (vtkUnstructuredGrid,1) — the input mesh. a vtkUnstructuredGrid, as one does.
• -imeshfile MeshInputFileName (str,1) — filename for the default Mesh reader. same energy, mesh edition.
• -entityidsarray CellEntityIdsArrayName (str,1); default=CellEntityIds — name of the array where entity ids have been stored. default is literally CellEntityIds. she's not trying to be mysterious.
• -lowthreshold LowThreshold (int,1); default=0 — lower threshold for surface filtering. default 0.
• -highthreshold HighThreshold (int,1); default=1 — higher threshold for surface filtering. default 1. so out of the box you're grabbing the 0-to-1 girls only. narrow. exclusive. very clique. 💅
• -osurfacefile SurfaceOutputFileName (str,1) — filename for the default Surface writer. where the surface goes to live its best life.
• -omeshfile MeshOutputFileName (str,1) — filename for the default Mesh writer. ditto, mesh nation.

🌈 Output arguments

and here's what she hands back to you. you're welcome. 😌

• -id Id (str,1); default=0 — the script id, again. she comes in and out, symmetrical queen.
• -handle Self (self,1) — handle to self, again. consistency is a love language. 💜
• -osurface Surface (vtkPolyData,1) — the output surface. the filtered cutie. vtkPolyData forever.
• -omesh Mesh (vtkUnstructuredGrid,1) — the output mesh. the filtered grid bestie. vtkUnstructuredGrid.
• -entityidsarray CellEntityIdsArrayName (str,1); default=CellEntityIds — name of the array where entity ids have been stored. still CellEntityIds. still slaying.

---

heads up bestie: a bunch of these arguments are positional-ish with fixed arity (str,1, bool,1, int,1, and the vtk object ones which take 1), so when you're chaining her into a pipeline, keep the order the way she lists it. she's flexible, but she's not chaotic. ok maybe a little chaotic. 🧚

and that's the tea, bestie — go threshold something and make it cute. 💖🌸🦋
