OFF_NORMALS(1)

NAME 💖

off_normals — utility for working with normals. Yes bestie, this is the off_normals(1) page from User Commands, hi 🫶.

SYNOPSIS 🦋

off_normals [options] [input_file]

DESCRIPTION 💅

Okay so off_normals displays normals of faces, implicit edges, and vertices. If input_file is not given, the program reads from standard input. No cap, that's the whole vibe.

✨ Options ✨

• -h,--help — this help message (run off_util -H help for general help). 💖
• --version — version information.
• -l <lim> — minimum distance for unique vertex locations as negative exponent. Default: 12 giving 1e-12.
• -o <file> — write output to file. Default: write to standard output.

🌟 Scene Options 🌟

• -t — normal position. n — natural, a — add element centers. Default: n.
• -u — unit normals.
• -e — connect to element centroid (for reference).
• -p <opt> — force polarity. o — outward, i — inward, r — reverse both inward and outward.
• -i <elms> — include normals. The element string can include o, i and h to show outward, inward and hemispherical. note: exclusion occurs before -p. Default: oih.
• -s <elms> — include elements. The element string can include v, e and f to show vertices, edges and faces. Default: f.
• -d <opt> — delete elements. f — delete faces of excluded normals. a — delete all of original model.
• -c <opts> — average pattern string for edge and vertex normals. Done before -p. r — raw, o — outward, i — inward, u — unit. Default: r.
• -a — alternate calculation for vertex normals.
• -x <opt> — face normals: n — Newell's, t — triangles, q — quads. Default: n.
• -C <xyz> — center of model for normals, three comma separated coordinates. 0 for origin. Default: centroid.

🎨 Coloring Options 🎨

Run off_util -H color for help on color formats. 🌈

• -O <col> — outward normal vertex color.
• -I <col> — inward normal vertex color. Default: vertex color is negative of outward col.
• -H <col> — hemispherical normal vertex color. Default: gray50.
• -E <col> — normal vector color. Connected to element centroid. Default: color of normal vertex. keyword: r take random color.
• -B <col> — normal vector base color. Color at element centroid. keyword: b take color of element (default). keyword: n take color of normal vertex.

SEE ALSO 📚

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

info off_normals

should give you access to the complete manual. Go read it, bestie, it's giving complete-manual energy 📖✨.
