✨ EVOLVER-OGL-Q ✨

okay bestie, gather round 💖 this is the manual page for evolver-ogl-q, aka The Surface Evolver but with the OpenGL/GLUT display and quadruple precision floating point format. yes. both. she's extra like that 💅

🌸 NAME 🌸

evolver-ogl-q — The Surface Evolver program with OpenGL/GLUT display and quadruple precision floating point format ✨

🦋 SYNOPSIS 🦋

evolver-ogl-q [-a][-d][-e][-i][-m][-q][-w][-x][-y][-h][-V] [-f FILE]
[-pN] [DATAFILE]

like. look at her. a whole lil bouquet of flags 🌷

💜 DESCRIPTION 💜

The Surface Evolver is an interactive program for the modelling of liquid surfaces shaped by various forces and constraints. no cap 🫶

so basically — and this is the whole vibe — the Surface Evolver minimizes the energy of triangulated surfaces according to designated energies and constraints. that's it. that's the girl boss job.

This man page mainly documents command line options and environment variables. everything else lives in the big manual (we'll get to her, don't worry).

✨ OPTIONS ✨

one bullet per flag, all facts intact, let's GO 🎀

  • -a — Autoconvert to named quantities when needed (default is on). want her OFF? use -a- to deactivate autoconversion. yes that's the syntax, not a typo, bestie.
  • -d — Begin with parser debugging on (equivalent to the debug runtime command). ⚠️ beware of copious output. like. SO much output.
  • -e — Echo stdin to stdout; meant for testing piped input.
  • -f FILE — After loading DATAFILE, read commands from FILE, then drop you at the command line prompt.
  • -i — Preserve DATAFILE numbers for element id's, rather than renumbering. she keeps her original ids, iconic.
  • -m — Begin with memory debugging on (equivalent to the memdebug runtime command). ⚠️ also beware of copious output. fr fr.
  • -pN — Run with N concurrent processes. multitasking queen 👑
  • -q — Convert to named quantities at start (equivalent to the convert_to_quantities runtime command).
  • -w — Exit immediately after any warning or error message; meant for batch runs.
  • -x — Exit immediately after any error message; meant for batch runs.
  • -y — Break to user prompt after any warning message.
  • -h — Display this help, then exit.
  • -V — Display the version and the banner, then exit.
tiny note: -w, -x and -y are all about how she reacts when things go sideways. -w = no chill at all, bails on warnings and errors. -x = bails on errors only, warnings she can handle. -y = stops and asks you. choose your fighter 💀

🌈 AVAILABILITY 🌈

The latest version of the Surface Evolver, up-to-date documentation, and more are available on-line from:

go get her 🫶

here's exactly what she says about herself:

Surface Evolver Version 2.70a (Debian 2.70+ds-10), August 27, 2013,
64-bit.  Compiled for float128, 33 digits precision.  Built with
Geomview support.  Built with OpenGL/GLUT display.

33 digits of precision. she's not like other girls 💅✨

🧚 ENVIRONMENT 🧚

  • EVOLVERPATH — Colon-separated list of paths automatically searched for datafiles, included files, or on-line help documentation. by default, the paths /usr/share/doc/evolver/html and /usr/share/doc/evolver/examples are appended (in that order); and this default behaviour can be cancelled by appending at least three consecutive colons (":::") at its end. yes, three. not two. THREE. 👀

🎀 FILES 🎀

  • ~/.evolver_history — Per user command history file. the receipts 🍓
  • /usr/share/doc/evolver/manual.pdf — The (complete) Surface Evolver Manual in PDF format.
  • /usr/share/doc/evolver/EvolverDoc.html — The HTML version of the Surface Evolver Manual that contains what the PDF manual has, modulo some advanced material.
  • /usr/share/doc/evolver/examples/ — This folder contains sample material, mainly datafiles and command-files, for the Surface Evolver.
