VMTKCENTERLINEGEOMETRY(1)

✨ NAME ✨

okay so bestie, introducing vmtkcenterlinegeometry — it's a vmtk script, she's iconic, she's giving main character energy 💅

🎀 DESCRIPTION 🎀

Auto-piping? Parsing options? slay, yes — vmtkcenterlinegeometry does the automatic piping thing, and also the parsing options thing, and it's literally the same script name doing both. iykyk 🫶

Here's the tea, fr fr: vmtkcenterlinegeometry computes the local geometry of centerlines in terms of curvature and torsion. that's it. that's the whole vibe. 🌀

🌸 Input arguments 🌸

these are the ones you hand her on the way in:

• -id Id (str,1); default=0 — the script id. classic.
• -handle Self (self,1) — a handle to self. she's holding her own hand, we love a self-love moment 🫶
• -disabled Disabled (bool,1); default=0 — turns off execution and piping. like, she will not run, she will not pipe, she will simply not. 💀
• -i Centerlines (vtkPolyData,1) — the input centerlines. the moment. the material. ✨
• -ifile CenterlinesInputFileName (str,1) — filename for the default Centerlines reader.
• -lengtharray LengthArrayName (str,1); default=Length — tells her what to call the array where the length values get stored.
• -curvaturearray CurvatureArrayName (str,1); default=Curvature — name of the array where curvature values get stored.
• -torsionarray TorsionArrayName (str,1); default=Torsion — name of the array where torsion values get stored.
• -tortuosityarray TortuosityArrayName (str,1); default=Tortuosity — name of the array where tortuosity values get stored.
• -frenettangentarray FrenetTangentArrayName (str,1); default=FrenetTangent — name of the array where the tangent vectors of the Frenet reference system get stored. Frenet girlies rise 🧚
• -frenetnormalarray FrenetNormalArrayName (str,1); default=FrenetNormal — name of the array where the normal vectors of the Frenet reference system get stored.
• -frenetbinormalarray FrenetBinormalArrayName (str,1); default=FrenetBinormal — name of the array where the binormal vectors of the Frenet reference system get stored. that's all three, she's complete, periodt 👑
• -smoothing LineSmoothing (bool,1); default=0
• -outputsmoothed OutputSmoothedLines (bool,1); default=0
• -iterations NumberOfSmoothingIterations (int,1) >= 0; default=100
• -factor SmoothingFactor (float,1) >= 0.0; default=0.1
• -ofile CenterlinesOutputFileName (str,1) — filename for the default Centerlines writer.

🌈 Output arguments 🌈

and these are the ones she hands back to you, bestie:

• -id Id (str,1); default=0 — the script id, again, because she contains multitudes.
• -handle Self (self,1) — handle to self. still holding her own hand.
• -o Centerlines (vtkPolyData,1) — the output centerlines 🎀
• -lengtharray LengthArrayName (str,1); default=Length — name of the array where length values are stored.
• -curvaturearray CurvatureArrayName (str,1); default=Curvature — name of the array where curvature values are stored.
• -torsionarray TorsionArrayName (str,1); default=Torsion — name of the array where torsion values are stored.
• -tortuosityarray TortuosityArrayName (str,1); default=Tortuosity — name of the array where tortuosity values are stored.

lowkey important: yes, the same four array names show up on both the input and the output side. no, i'm not editing that out. that's canon. 🙈

okay that's literally the whole page, you're so welcome 💖
