VMTKBIFURCATIONVECTORS(1)

✨ NAME ✨

vmtkbifurcationvectors — bestie, it's a vmtk script, and it's literally called vmtkbifurcationvectors 💅

🦋 DESCRIPTION 🦋

Okay so first things first: the top of this page is giving "Automatic piping vmtkbifurcationvectors" plus "Parsing options vmtkbifurcationvectors" — that's the auto-generated boilerplate energy, the machinery that wires up the pipes and chews through your flags. It's the scaffolding, not the star of the show. 🎀

The actual main character? vmtkbifurcationvectors calculates in plane and out of place bifurcation vectors for a centerline. (Yes, the script fr says "out of place" and not "out of plane" — we don't make the rules, we just report them. 😭) The way that it works: you hand it a centerline, it hands you back vectors. Iconic.

💖 Input arguments 💖

• -id Id (str,1); default=0 — the script id 🪪
• -handle Self (self,1) — handle to self, the little self-reference moment 🫶
• -disabled Disabled (bool,1); default=0 — disable execution and piping, aka the "not me doing anything today" switch 💀
• -i Centerlines (vtkPolyData,1) — the input split centerlines 🌸
• -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 🏷️
• -centerlineidsarray CenterlineIdsArrayName (str,1); default=CenterlineIds — name of the array where centerline ids are stored 🏷️

• -upnormalarray ReferenceSystemsUpNormalArrayName (str,1); default=UpNormal — name of the array where reference system upnormal vectors are stored ✨
• -vectorsarray BifurcationVectorsArrayName (str,1); default=BifurcationVectors — that's the array name, no extra notes from the script itself 💅
• -inplanevectorsarray InPlaneBifurcationVectorsArrayName (str,1); default=InPlaneBifurcationVectors — the in-plane vectors array name 🎀
• -outofplanevectorsarray OutOfPlaneBifurcationVectorsArrayName (str,1); default=OutOfPlaneBifurcationVectors — the out-of-plane vectors array name 🎀
• -inplaneanglesarray InPlaneBifurcationVectorAnglesArrayName (str,1); default=InPlaneBifurcationVectorAngles — the in-plane vector angles array name 📐
• -outofplaneanglesarray OutOfPlaneBifurcationVectorAnglesArrayName (str,1); default=OutOfPlaneBifurcationVectorAngles — the out-of-plane vector angles array name 📐
• -orientationarray BifurcationVectorsOrientationArrayName (str,1); default=BifurcationVectorsOrientation — the orientation array name 🧭
• -bifurcationgroupidsarray BifurcationGroupIdsArrayName (str,1); default=BifurcationGroupIds — the bifurcation group ids array name 🏷️
• -normalizevectors NormalizeBifurcationVectors (bool,1); default=0 — normalize the bifurcation vectors (off by default, so it's a 0 unless you say otherwise) ✨
• -ofile BifurcationVectorsOutputFileName (str,1) — filename for the default BifurcationVectors writer 📝

🫶 Output arguments 🫶

• -id Id (str,1); default=0 — the script id 🪪
• -handle Self (self,1) — handle to self 🫶
• -o BifurcationVectors (vtkPolyData,1) — the output data, the whole point of the outing 👑
• -vectorsarray BifurcationVectorsArrayName (str,1); default=BifurcationVectors — the vectors array name 💅
• -inplanevectorsarray InPlaneBifurcationVectorsArrayName (str,1); default=InPlaneBifurcationVectors — the in-plane vectors array name 🎀
• -outofplanevectorsarray OutOfPlaneBifurcationVectorsArrayName (str,1); default=OutOfPlaneBifurcationVectors — the out-of-plane vectors array name 🎀
• -inplaneanglesarray InPlaneBifurcationVectorAnglesArrayName (str,1); default=InPlaneBifurcationVectorAngles — the in-plane vector angles array name 📐
• -outofplaneanglesarray OutOfPlaneBifurcationVectorAnglesArrayName (str,1); default=OutOfPlaneBifurcationVectorAngles — the out-of-plane vector angles array name 📐
• -orientationarray BifurcationVectorsOrientationArrayName (str,1); default=BifurcationVectorsOrientation — the orientation array name 🧭
• -bifurcationgroupidsarray BifurcationGroupIdsArrayName (str,1); default=BifurcationGroupIds — the bifurcation group ids array name 🏷️

Heads up bestie: a bunch of these flags show up in both the input and the output lists (-id, -handle, -vectorsarray, -inplanevectorsarray, -outofplanevectorsarray, -inplaneanglesarray, -outofplaneanglesarray, -orientationarray, -bifurcationgroupidsarray). That's just how the script lists them — no cap, I'm not merging anything. 🌈

And that's a wrap, fr fr 💖 this is vmtkbifurcationvectors 1.5, dated April 2026, and yes I read the footer so you don't have to. Go forth and calculate your vectors, you absolute icon. ✨👑🥳
