VMTKBRANCHGEOMETRY(1)

✨ NAME ✨

vmtkbranchgeometry — the vmtk script that's literally just called vmtkbranchgeometry, bestie, no cap 💅

💖 DESCRIPTION 💖

Automatic piping, vmtkbranchgeometry, parsing options, vmtkbranchgeometry — that's the whole intro, we move fast here 🏃‍♀️💨

So like, vmtkbranchgeometry computes geometric parameters for every branch of a tree. It takes as input the centerlines that have already been split into branches, okay? So do that first, don't come at me 😭

🎀 Input arguments 🎀

• -id Id (str,1); default=0 — the script id, just the little name tag for this run 🏷️
• -handle Self (self,1) — handle to self, it's giving main character energy fr
• -disabled Disabled (bool,1); default=0 — set this to disable execution and piping. It's the "not me today" switch 🙈
• -i Centerlines (vtkPolyData,1) — the input split centerlines, the actual star of the show 👑
• -ifile CenterlinesInputFileName (str,1) — filename for the default Centerlines reader
• -radiusarray RadiusArrayName (str,1); default=MaximumInscribedSphereRadius — name of the array where centerline radius values are stored
• -groupidsarray GroupIdsArrayName (str,1); default=GroupIds — name of the array where centerline group ids are stored
• -blankingarray BlankingArrayName (str,1); default=Blanking — name of the array where blanking information about branches is stored
• -lengtharray LengthArrayName (str,1); default=Length — name of the array where the average length of each branch has to be stored
• -curvaturearray CurvatureArrayName (str,1); default=Curvature — name of the array where the average curvature of each branch has to be stored
• -torsionarray TorsionArrayName (str,1); default=Torsion — name of the array where the average torsion of each branch has to be stored
• -tortuosityarray TortuosityArrayName (str,1); default=Tortuosity — name of the array where the average tortuosity of each branch has to be stored, and tortuosity is defined as the length of a line divided by the distance of its endpoints ✨
• -smoothing LineSmoothing (bool,1); default=0 — smoothing on/off, lowkey just a toggle
• -iterations NumberOfSmoothingIterations (int,1) >= 0; default=100 — how many smoothing iterations, and it has to be >= 0
• -factor SmoothingFactor (float,1) >= 0.0; default=0.1 — the smoothing factor, and it has to be >= 0.0
• -ofile GeometryDataOutputFileName (str,1) — filename for the default GeometryData writer

🌸 Output arguments 🌸

• -id Id (str,1); default=0 — the script id again, iconic honestly
• -handle Self (self,1) — handle to self, yes again, it lives here too 💖
• -o GeometryData (vtkPolyData,1) — the output data set, the whole point of the mission 🦋
• -lengtharray LengthArrayName (str,1); default=Length — name of the array where the average length of each branch is stored
• -curvaturearray CurvatureArrayName (str,1); default=Curvature — name of the array where the average curvature of each branch is stored
• -torsionarray TorsionArrayName (str,1); default=Torsion — name of the array where the average torsion of each branch is stored
• -tortuosityarray TortuosityArrayName (str,1); default=Tortuosity — name of the array where the average tortuosity of each branch is stored, and out here tortuosity is defined as the length of a line divided by the distance of its endpoints minus one (L/D - 1). Note it's minus one on the output side and no minus one on the input side — she contains multitudes, don't @ me 😭✨

🫶 okay that's literally the whole page, you ate this, go compute some branch geometry and slay 💅
