DPLOT(nged)

draws plotfiles from the given logfile

📅 published 7.44.0, from nixpkgs unstable

okay bestie, welcome to DPLOT(nged) — the nged manual page for the dplot command 💖 this one is lowkey niche but highkey useful if you're deep in intersection debugging.

🌸 NAME 🌸

dplot — draws plotfiles from the given logfile. periodt. ✨

✨ SYNOPSIS ✨

dplot logfile cmd [args]

💖 DESCRIPTION 💖

The dplot command parses a log file generated by the B-Rep surface-surface intersection (SSI) routines and visually renders the geometry intersections using MGED's overlay system. It's primarily a debugging tool for analyzing NURBS intersection events, iykyk 🧚

It requires a logfile (usually a .plot3 file generated by the evaluator) and a cmd to specify what geometry to plot. The command is stateful and will prompt the user to "Press [Enter]" to advance through sequential events. So yeah, it's gonna make you tap Enter a bunch — main character energy, honestly 💅

The available cmd subcommands are:

  • ssx — show all intersecting surface pairs.
  • ssx N — show intersections specifically for surface-surface intersection (SSX) pair N.
  • isocsx N — show intersecting isocurve-surface pairs for SSX pair N.
  • isocsx N M — show intersections of SSX pair N, specifically for isocurve-surface pair M.
  • fcurves N — show clipped face curves for SSX pair N.
  • lcurves — show linked SSX curves used to split faces.
  • faces — show split faces used to construct the final boolean result.

🎀 EXAMPLES 🎀

🌈 Example 1. Iterate through intersecting surface pairs

mged> dplot intersect.log ssx

Parses intersect.log and visually overlays the first surface-surface intersection pair, prompting the user to press Enter to advance to the next pair. adorable little step-through vibe 🦋

🌈 Example 2. View clipped face curves for a specific intersection

mged> dplot intersect.log fcurves 2

Displays the clipped face curves associated with the third (0-indexed 2) surface-surface intersection pair recorded in intersect.log. yes bestie, zero-indexed — count like a programmer 🔥
