VMTKBOUNDARYREFERENCESYSTEMS(1)

💖 NAME 💖

vmtkboundaryreferencesystems — ok bestie this is a vmtk script, and its whole name is literally vmtkboundaryreferencesystems, no notes ✨

🌸 DESCRIPTION 🌸

So. Automatic piping, vmtkboundaryreferencesystems, parsing options, vmtkboundaryreferencesystems. That's the whole vibe of the pipeline, no cap 💅

Now the actual tea, vmtkboundaryreferencesystems computes the reference systems relative to each open boundary of a model 🦋 A super typical glow-up use for this is specifying boundary conditions for CFD simulations, periodt. The reference systems get handed to you both as origin and normal, and as origin plus a first point that defines the x axis together with the origin, plus a second point that defines the xy plane together with the former two ✨

🫶 Input arguments 🫶

• -id Id (str,1); default=0 — the script id, iconic
• -handle Self (self,1) — handle to self, she's holding her own hand 🫶
• -disabled Disabled (bool,1); default=0 — disable execution and piping, in case you need her to sit down and chill
• -i Surface (vtkPolyData,1) — the input surface, the main character of this whole operation 👑
• -ifile SurfaceInputFileName (str,1) — filename for the default Surface reader
• -boundaryradiusarray BoundaryRadiusArrayName (str,1); default=BoundaryRadius — name of the array where the mean radius of each boundary has to be stored
• -boundarynormalsarray BoundaryNormalsArrayName (str,1); default=BoundaryNormals — name of the array where outward pointing normals to each boundary have to be stored
• -point1array Point1ArrayName (str,1); default=Point1 — name of the array where the coordinates of a point of each boundary have to be stored
• -point2array Point2ArrayName (str,1); default=Point2 — name of the array where the coordinates of a second point of each boundary have to be stored
• -ofile ReferenceSystemsOutputFileName (str,1) — filename for the default ReferenceSystems writer

🎀 Output arguments 🎀

• -id Id (str,1); default=0 — the script id, she's back and she's still iconic
• -handle Self (self,1) — handle to self, again, self-love fr fr 💜
• -o ReferenceSystems (vtkPolyData,1) — the output reference systems, given as points coinciding with the origins ⭐
• -boundaryradiusarray BoundaryRadiusArrayName (str,1); default=BoundaryRadius — name of the array where the mean radius of each boundary has to be stored
• -boundarynormalsarray BoundaryNormalsArrayName (str,1); default=BoundaryNormals — name of the array where outward pointing normals to each boundary are stored
• -point1array Point1ArrayName (str,1); default=Point1 — name of the array where the coordinates of a point of each boundary are stored
• -point2array Point2ArrayName (str,1); default=Point2 — name of the array where the coordinates of a second point of each boundary are stored

lowkey obsessed with how the input versions say stuff "has to be stored" and the output versions just say it "are stored" — character development, honestly 😭💀

And that's the whole page, bestie 🫶 this was vmtkboundaryreferencesystems version 1.5, dated April 2026 — mwah, go forth and slay your boundary conditions 💅✨🌈
