VMTKCENTERLIN...SETATTRIBUTES(1)

💖 NAME 💖

vmtkcenterlineoffsetattributes — okay so it's a vmtk script, and it's literally just called vmtkcenterlineoffsetattributes. Say it with me. Slay. ✨

🌸 DESCRIPTION 🌸

Bestie, this one is Automatic piping vmtkcenterlineoffsetattributes and — yes — Parsing options vmtkcenterlineoffsetattributes. That's the whole vibe up top. 🙈

Here's the tea, fr fr: vmtkcenterlineoffsetattributes offsets centerline attributes relative to a bifurcation reference system, and it does it in such a way that:</br>

• the abscissa of the closest point to the origin is zero, and
• the centerline normal at that point coincides with the bifurcation reference system normal.

It's giving "line up your centerlines with the bifurcation energy." Periodt. 💅

🫶 Input arguments 🫶

• -id Id (str,1); default=0 — the script id, bestie
• -handle Self (self,1) — handle to self. yes she's holding herself, main character energy 👑
• -disabled Disabled (bool,1); default=0 — disables execution and piping, iykyk
• -i Centerlines (vtkPolyData,1) — the input split centerlines 🌈
• -ifile CenterlinesInputFileName (str,1) — filename for the default Centerlines reader
• -referencesystems ReferenceSystems (vtkPolyData,1) — the bifurcation reference systems
• -referencesystemsfile ReferenceSystemsInputFileName (str,1) — filename for the default ReferenceSystems reader
• -referencegroupid ReferenceGroupId (int,1); default=-1 — group id of the reference system to which attributes have to be offset
• -replaceattributes ReplaceAttributes (bool,1); default=1 — overwrite the existing attributes. so bold of her 💀
• -abscissasarray AbscissasArrayName (str,1); default=Abscissas — name of the array where centerline abscissas are stored
• -normalsarray NormalsArrayName (str,1); default=ParallelTransportNormals — name of the array where centerline normals 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
• -referencesystemsnormalarray ReferenceSystemsNormalArrayName (str,1); default=Normal — name of the array where reference system normals are stored
• -offsetabscissasarray OffsetAbscissasArrayName (str,1); default=OffsetAbscissas — name of the array where offset centerline abscissas have to be stored if ReplaceAttributes is off ⚠️
• -offsetnormalsarray OffsetNormalsArrayName (str,1); default=OffsetNormals — name of the array where offset centerline normals have to be stored if ReplaceAttributes is off ⚠️
• -interactive Interactive (bool,1); default=0 — that's it, that's the description, she contains multitudes 🦋
• -renderer vmtkRenderer (vmtkRenderer,1) — external renderer
• -ofile CenterlinesOutputFileName (str,1) — filename for the default Centerlines writer

👑 Output arguments 👑

• -id Id (str,1); default=0 — script id again, she said round two 💫
• -handle Self (self,1) — handle to self, still holding herself, still iconic
• -o Centerlines (vtkPolyData,1) — the output centerlines 🎀
• -referencegroupid ReferenceGroupId (int,1); default=-1 — group id of the reference system to which attributes are offset
• -offsetabscissasarray OffsetAbscissasArrayName (str,1); default=OffsetAbscissas — name of the array where offset centerline abscissas are stored if ReplaceAttributes is off
• -offsetnormalsarray OffsetNormalsArrayName (str,1); default=OffsetNormals — name of the array where offset centerline normals are stored if ReplaceAttributes is off
• -abscissasarray AbscissasArrayName (str,1); default=Abscissas — name of the array where centerline abscissas are stored
• -normalsarray NormalsArrayName (str,1); default=ParallelTransportNormals — name of the array where centerline normals are stored

Lowkey note: the input and output lists are basically twins, and yes, -id and -handle Self show up in both. Not me pointing that out. It's real, it's canon, don't @ me. 🫶

And that's the whole page, bestie — we ATE. 💅✨ No cap: this is vmtkcenterlineoffsetattributes version 1.5, dated April 2026, from the User Commands manual. Go offset some attributes, you absolute legend. 🦋💖🌸
