VMTKNUMPYTOMESH(1)

💖 NAME 💖

vmtknumpytomesh — it's a vmtk script, bestie, and its whole name is literally vmtknumpytomesh. That's it, that's the name. She's giving "User Commands" energy if you were wondering what manual section she lives in. 🌸

✨ DESCRIPTION ✨

Okay so first things first: there's some automatic piping going on for vmtkNumpyToMesh, plus option parsing for vmtkNumpyToMesh. Very boilerplate, very "the script wires itself up", love that for her. 💅

Now the actual tea. 🍓

vmtkNumpyToMesh takes a nested python dictionary whose values are numpy arrays, and those arrays specify Points, PointData, Cells, CellData, and CellPointIds — which is the stuff that describes the connectivity, iykyk. And then she hands you back a VMTK mesh, aka a VTK Unstructured Grid object. Iconic. ✨

🫶 Input arguments

Here's everything you can feed her on the way in:

• -id Id (str,1); default=0 — the script id. Just an id. She needs one, okay? 😌
• -handle Self (self,1) — a handle to self. Self-care, literally. 🪞
• -disabled Disabled (bool,1); default=0 — turns off execution and piping. The "not me today" switch. 💀
• -i ArrayDict (dict,1) — the input array dictionary. Your whole lil nested dict of numpy arrays goes right here. 🎀
• -ifile ArrayDictInputFileName (str,1) — the filename for the default ArrayDict reader. So instead of handing her the dict directly, you point at a file and she reads it. 🦋
• -flatten FlattenListOfCells — enable this to convert cells that are formatted as a list of numpy arrays into the default flat structure. That's the entire vibe of this flag, no cap. 🧚
• -ofile MeshOutputFileName (str,1) — the filename for the default Mesh writer. Where the mesh goes when she's done. 💜

👑 Output arguments

And here's what she gives you back:

• -id Id (str,1); default=0 — the script id again. Same girl, output side. 💖
• -handle Self (self,1) — handle to self again. She contains multitudes (and also references herself twice). 🙈
• -o Mesh (vtkUnstructuredGrid,1) — the output mesh!! Your vtkUnstructuredGrid. The main character. ⭐

Heads up bestie: -id and -handle show up in both the input arguments and the output arguments, and that's not a typo, that's just how the page is. Both are real, both count. 🫶

That's the whole scroll, fr fr. This was vmtknumpytomesh 1.5, dated April 2026 — slay, she's from the future and she still only does one thing: numpy dict in, unstructured grid out. Periodt. 👑🌈
