VMTKNETWORKEXTRACTION(1)

💖 NAME 💖

vmtknetworkextraction — the vmtk script that pulls a whole lil network of centerlines out of your surface, bestie ✨

🦋 DESCRIPTION 🦋

okay so. Automatic piping. vmtknetworkextraction. Parsing options. vmtknetworkextraction. That's the whole vibe at the top, and now the tea ☕

vmtknetworkextraction extracts a network of approximated centerlines from a surface. and listen — the surface must have at least an opening. no opening, no network, that's just how it is 🙈

fr fr, an enclosed surface with zero openings is not gonna cooperate here. give it a hole. give it an opening. it needs one. periodt 💅

🌸 Input arguments 🌸

• -id Id (str,1); default=0 — the script id, iykyk
• -handle Self (self,1) — handle to self 👑
• -disabled Disabled (bool,1); default=0 — disables execution and piping when you flip it
• -i Surface (vtkPolyData,1) — the input surface, the main character of this whole operation
• -ifile SurfaceInputFileName (str,1) — filename for the default Surface reader
• -advancementratio AdvancementRatio (float,1) >= 1.0; default=1.05 — the ratio between the sphere step and the local maximum radius
• -radiusarray RadiusArrayName (str,1); default=Radius — the name of the radius array
• -topologyarray TopologyArrayName (str,1); default=Topology — the name of the topology array
• -marksarray MarksArrayName (str,1); default=Marks — the name of the marks array
• -ofile NetworkOutputFileName (str,1) — filename for the default Network writer
• -ographfile GraphLayoutOutputFileName (str,1) — filename for the default GraphLayout writer

💜 Output arguments 💜

• -id Id (str,1); default=0 — the script id, yes it shows up again, it's that iconic ✨
• -handle Self (self,1) — handle to self
• -o Network (vtkPolyData,1) — the output network 🎀
• -ograph GraphLayout (vtkPolyData,1) — the output graph layout 🌈

that's the whole page bestie, every single flag accounted for, nothing skipped, we ate and left no crumbs 🍓
