ROT_POINT(nged)

🎀 rot_point(nged) — the glow-up your points deserve 🎀

okay bestie, so you know how your view in MGED gets all rotated and you're like "wait what even IS this point now"? yeah. rot_point is literally the answer. it's a BRL-CAD User Command and it's giving main character energy, ngl.

✨ NAME ✨

rot_point — transform a point by the inverse of the current view rotation 💅

like, it takes a point and un-rotates it. periodt.

---

🌸 SYNOPSIS 🌸

rot_point x y z
rot_point "x y z"

two ways, same slay. pick your fighter 🫶

---

🦋 DESCRIPTION 🦋

so the rot_point command applies the inverse of the current view rotation matrix to the point you hand it, and returns the transformed point as a space-separated triplet. that's it, that's the whole vibe. ✨

your input point can come in as three separate floating-point arguments, or as a single quoted space-separated triplet — both are valid, no cap. the output is a space-separated x y z string of the resulting point coordinates.

⚠️ okay important note, bestie, do NOT sleep on this: the command applies the inverse of the view rotation matrix — not the forward rotation. this transforms a point from view-rotated space back into unrotated model space orientation, which is basically "un-rotating" the point by however much the view has been rotated. 🔥

and heads up, this is distinct from model2view — that one applies the full model-to-view transform, including scale and translation. rot_point is just the rotation-inverse situation. don't mix them up, iykyk 😭

💖 EXAMPLES 💖

Example 1. Transform a point using three separate arguments

mged> rot_point 10 0 0

transforms the point (10, 0, 0) by the inverse of the current view rotation and returns the result as three space-separated values. iconic. 👑

Example 2. Transform a point using a quoted triplet

mged> rot_point "10 0 0"

equivalent to the above — the single quoted string form is accepted for scripting convenience. literally the same thing, just packaged cuter 🎀

Example 3. Use in a scripting context

mged> set rp [rot_point 0 0 100]

stores the inverse-rotation-transformed version of (0, 0, 100) in the Tcl variable rp for use in subsequent calculations. this is the one for the coders fr fr 💻✨
