VMTKPARTICLETRACER(1)

👑 NAME 👑

vmtkparticletracer — the vmtk script called vmtkparticletracer. Yeah bestie, that's the whole name section, it's giving minimalist 💅 (this one lives in section 1, the User Commands manual, in case you were wondering 🎀)

🌸 DESCRIPTION 🌸

Okay so, the boilerplate bit first, verbatim energy and all:

automatic piping vmtkparticletracer Parsing options vmtkparticletracer

and the actual headline of the whole thing:

vmtkparticletracer : generate streamlines ✨

That's the vibe. Streamlines. Generated. Iconic.

💜 Output arguments 💜

• -id Id — (str,1); default=0 — script id, yes she's listed twice, the page said so, we don't question the page 💅
• -handle Self — (self,1) — handle to self. also listed twice. also iconic.
• -o Traces — (vtkPolyData,1) — the output traces 🎀

ngl, the output list is short and sweet but that's literally everything it had, I'm not gatekeeping a single flag from you 🫶

and that's a wrap, bestie 💖 this whole page is from vmtkparticletracer version 1.5, dated April 2026 — go forth and generate those streamlines, you absolute legend 👑✨
