OFF_QUERY(1)

📦 version 0.32, in nixos 26.05, nixpkgs unstable

💖 NAME 💖

okay so bestie, this is off_query(1) — the OFF_QUERY manual page — and its whole main character job is list element data. That's it. That's the vibe. 🎀

✨ SYNOPSIS ✨

off_query [options] query [input_file]

🦋 DESCRIPTION 🦋

So you read a file in OFF format, and off_query lists element data for the elements you specify. No cap. ✨

Added elements of the query type are also added to the query list. Added elements are referred to by xN, where N is the order the element was added (starting with 0). Lowkey important: that 0 is the first one, not 1. 🙈

query is a list of letters. The first letter is the query element type — V, F, or E — and then the letters after it are the values to print. Iconic little code language, iykyk. 💅

🌸 V — Vertex

  • c — coordinates
  • d — distance from centre
  • f — face index numbs
  • F — face angles
  • a — solid angle
  • n — neighbours
  • o — order
  • g — vertex figure
  • K — colour

🧚 E — Edge

  • v — vertex index nums
  • d — distance from centre
  • f — face index nums
  • D — direction
  • a — diheral angle
  • l — length
  • c — central angle
  • C — centroid
  • K — colour

👑 F — Face

  • v — vertex index nums
  • d — distance from centre
  • n — neighbours
  • A — area
  • N — normal
  • C — centroid
  • a — angles
  • l — lengths
  • s — number of sides
  • p — max nonplanar distance
  • P — perimeter
  • K — colour

💅 OPTIONS 💅

  • -h,--help — this help message (run 'off_util -H help' for general help)
  • --version — version information
  • -c <cent> — centre of shape in form 'X,Y,Z', 0 to use origin, C to use centroid (default 0)
  • -I <idxs> — list of elements by index number given as index ranges separated by commas, range can be one number or two numbers separated by a hyphen (default range numbers: 0 and largest index, default argument: any added elements else '-')
  • -v <crds> — add vertex, coordinates in form 'X,Y,Z'
  • -f <vnos> — add face, a list of vertex index numbers separated by commas
  • -e <vnos> — add edges, a list of vertex index numbers separated by commas and taken in pairs
  • -k — keep orientation, don't try to orient the faces
  • -E <type> — edges for query, e - explicit edges, i - implicit edges, a - explicit and implicit (default)
  • -o <file> — write output to file (default: write to standard output)
  • -d <dgts> — number of significant digits (default 17) or if negative then the number of digits after the decimal point

The full documentation for off_query is maintained as a Texinfo manual. If the info and off_query programs are properly installed at your site, the command

info off_query

should give you access to the complete manual. Slay. 💖

💖 that's the whole page, bestie — off_query from Antiprism 0.32, footer says http://..., and the date part is literally not there, so that's the footer tea. periodt. 💖
