THREED(3NCARG)

💖 THREED 💖 — the 3-d line drawing package (yes bestie, from THREED(3NCARG), part of the NCAR Graphics fam 🎀)

okay so. picture this: you have points floating in actual literal 3-D space, and you want them on your flat little 2-D screen. that's THREED's whole thing. it's the 3-d line drawing package, and it is iconic. it takes your 3-space points, projects them, draws them. that's the vibe. ✨

🌸 NAME 🌸

THREED — the 3-d line drawing package. periodt. 💅

✨ SYNOPSIS ✨

here's the whole squad of routines, and what each one does. no cap, read all of them.

• CURVE3 — draws the projection of a curve, where that curve is defined by a sequence of points in 3-space. cute little squiggle, now flat. 🦋
• FENCE3 — does the exact same thing as CURVE3, but it also draws a "fence" of straight line segments. those segments are parallel to one of the three axes, and they extend all the way out to a specified plane that's perpendicular to that axis. it's giving picket fence but make it math. 🌈
• FRST3 — announces the first point in a sequence of points that are connected by straight-line segments, and whose projections are getting drawn. you call FRST3 for the first point, and then VECT3 for all the rest. main character energy for the first point only. 👑
• LINE3 — draws the projection of a straight-line segment. simple. clean. ate. ⭐
• PERIM3 — draws the projection of a rectangular perimeter, sitting in a plane parallel to one of the three coordinate planes, with inward-pointing tick marks at whatever intervals you specify. little ticky ticks, we love her. 🎀
• POINT3 — draws the projection of a point. that's it. that's the routine. one point, one dot, slay. 💖
• PWRZT — draws the projection of character strings that are positioned in a plane parallel to one of the three coordinate planes. text but in 3-D, iykyk. 🫶
• SET3 — defines the transformation from three dimensions to two dimensions. this is the whole "3-D → 2-D" pipeline, the translation of it all, literally. 🔥
• TICK43 — hands you the controls for tick mark length in PERIM3. your ticks, your rules. ✨
• VECT3 — defines the second point and every subsequent point in a sequence of points connected by straight-line segments, whose projections are being drawn. (FRST3 handles the first point, VECT3 handles the rest — yes we're saying it twice because the manpage says it twice and we keep every detail bestie 💜)

okay that's the whole page, you're officially a THREED girlie now 💅✨

this was THREED(3NCARG) from the UNIX manual, dated March 1993, and it's an NCAR Graphics situation — go forth and project some points, bestie 🦋💖🎀
