VMTKSURFACECURVATURE(1)

🌸 VMTKSURFACECURVATURE 🌸

okay bestie, gather round, because this is vmtksurfacecurvature — a User Commands girly from the VMTK fam, and she is all about that curvature life. no cap. 💅

---

✨ NAME ✨

vmtksurfacecurvature — literally just the vmtk script called vmtksurfacecurvature. she does what it says on the tin, and the tin says curvature. 🎀

---

💖 DESCRIPTION 💖

so here's the vibe: vmtksurfacecurvature does the automatic piping thing that all the vmtk scripts do (yes, the classic Automatic piping / Parsing options combo, it's giving family tradition), and then:

vmtksurfacecurvature : computes the curvature of an input surface, and — get this — optionally reports results back to a reference surface (by point id). that's the glow-up. 🦋

heads up bestie: there are two whole groups of arguments down here — the Input arguments and the Output arguments — and the same names show up in both (-id, -handle), so don't get it twisted. iykyk.

---

🌈 Input arguments 🌈

• -id — oh wait, the full name is Id, type (str,1), and the default is default=0. it's the script id, the little name tag she wears at the party. 💖
• -handle — Self, type (self,1). this is the handle to self, no default listed, it's just… her. main character energy, honestly. 👑
• -disabled — Disabled, type (bool,1), default=0. flip this and you disable execution and piping, i.e. she sits the whole thing out. sometimes you just need a nap. 😭
• -i — Surface, type (vtkPolyData,1). this is the input surface. THE moment. THE subject. ✨
• -ifile — SurfaceInputFileName, type (str,1). the filename for the default Surface reader, in case you'd rather hand her a file than an object. 🍓
• -r — ReferenceSurface, type (vtkPolyData,1). the reference surface — aka where the results go to get reported back by point id. 🫶
• -rfile — ReferenceSurfaceInputFileName, type (str,1). the filename for the default ReferenceSurface reader. yes, she even has a reader for the reference one. so thorough. 🧚
• -type — CurvatureType, type (str,1), and it has to be one of ['mean', 'gaussian', 'maximum', 'minimum']; default=mean. this picks the type of surface curvature to compute. mean is the default bestie but gaussian, maximum and minimum are all right there waiting their turn. 💜
• -absolute — AbsoluteCurvature, type (bool,1), default=0. turn it on and she'll output the absolute value of curvature — no more sad little negatives. ⭐
• -median — MedianFiltering, type (bool,1), default=0. this one outputs curvature after median filtering, which is the whole point: it suppresses numerical noise speckles. literally a skincare routine for your mesh. 🌸
• -boundaries — CurvatureOnBoundaries, type (bool,1), default=0. flip it to compute curvature on boundaries too, not just the cozy interior. 🎀
• -reciprocal — BoundedReciprocal, type (bool,1), default=0. outputs the bounded reciprocal of curvature. she's being polite about the denominator, we love a safe queen. 💅
• -epsilon — Epsilon, type (float,1), default=1.0. this is the bounded reciprocal epsilon at the denominator — the literal little buffer keeping that reciprocal from going feral. 🔥
• -offset — Offset, type (float,1), default=0.0. offsets the curvature by the specified value. default is a chill 0.0, so no sneaky shifting unless you ask. 🌈
• -ofile — SurfaceOutputFileName, type (str,1). the filename for the default Surface writer. where the curvature goes to live out its dreams. 💖

---

🦋 Output arguments 🦋

• -id — Id, type (str,1), default=0. yep, the script id again — she contains multitudes (and both an input and an output version of this arg). 🙈
• -handle — Self, type (self,1). the handle to self on the way back out. she's still her. iconic. ✨
• -o — Surface, type (vtkPolyData,1). the output surface — the one that's all curvy and gorgeous and ready to be piped onward. 💜

---

tiny reminder: everything above is vmtk's automatic piping + parsing options situation, so these args are meant to be piped around like a group chat. don't fight the pipeline, bestie. 🫶
