AET(nged)

💅 AET(nged) — the BRL-CAD glow-up for your viewpoint

okay bestie, so this is aet (and its little twin ae) from the BRL-CAD user commands fam — the tool that gets or sets your view orientation as azimuth, elevation, and twist. basically it's the main character of "which way am I even looking rn" 💖

---

✨ SYNOPSIS ✨

aet
aet [-i] az el [tw]
aet [-i] "az el [tw]"

---

🌸 DESCRIPTION 🌸

so the aet command (which also answers to ae, iconic of it) either gets or sets the current view orientation, expressed as azimuth, elevation, and an optional twist — all in degrees. no cap. 🎀

When you give it zero arguments, aet just hands you back the current view orientation as three space-separated floating-point values:

az el tw

When you give it arguments, aet sets the view rotation to whatever azimuth and elevation (and optional twist) you asked for, then updates the display. slay. 🔥

• Azimuth (az) — horizontal rotation about the vertical axis, measured in degrees. 0° looks from the front; 90° looks from the right. think of it as walking around your model in a circle 🦋
• Elevation (el) — vertical angle above or below the horizontal plane, in degrees. 90° looks straight down. very bird's-eye, very demure 🕊️
• Twist (tw) — roll rotation about the viewing axis, in degrees. it's optional and defaults to 0° if you don't mention it. the lowkey bonus angle 💫

---

🌈 Options

• -i — treat the angles you give as incremental offsets added on top of the current azimuth, elevation, and twist, instead of as absolute values. ngl this is the "nudge me a lil" mode 🫶

---

⭐ Input forms

you've got options, babe — angles can come in as two or three separate arguments (az el or az el tw), or as one single quoted space-separated string ("az el" or "az el tw"). and in every form, if twist is omitted it defaults to 0. periodt. 💅

🎀 EXAMPLES 🎀

Example 1. Get the current view orientation

mged> aet

returns the current azimuth, elevation, and twist in degrees — for example: 35 25 0. just a lil vibe check on where you're at 👑

Example 2. Set the view to azimuth 35, elevation 25

mged> aet 35 25

sets the view to azimuth 35°, elevation 25°, twist 0°. chef's kiss ✨

Example 3. Set azimuth, elevation, and twist together

mged> aet 45 30 15

sets the view to azimuth 45°, elevation 30°, twist 15°. all three angles, all three vibes 🍓

Example 4. Rotate the view incrementally

mged> aet -i 10 0

adds 10° to the current azimuth without changing elevation or twist. tiny rotate, big impact 😌

Example 5. Set orientation using a quoted string

mged> aet "270 0"

sets the view to look from the left side (azimuth 270°, elevation 0°). quoted string girlies, this one's for you 🧚
