FIND_ARB_EDGE(nged)

💅 find_arb_edge — find & identify an ARB edge (nged)

okay so bestie, welcome to find_arb_edge from the BRL-CAD user commands fam ✨ this is the one that plays detective for ARB (Arbitrary Polyhedron) primitives 🔍💖

---

🌸 SYNOPSIS 🌸

find_arb_edge arb "view_x view_y view_z" ptol

---

✨ DESCRIPTION ✨

so the find_arb_edge command goes snooping around inside an ARB (Arbitrary Polyhedron) primitive and hunts down the edge that's closest to a view coordinate you give it — all within a pick tolerance (ptol) that you get to set. no cap, it's giving "where's waldo but for polygon edges" 🕵️‍♀️🎀

if it works (and it should, fingers crossed 🫶), the command hands you back three integers:

1. the numeric ID of the closest edge 👑
2. the numeric ID of the first vertex (vi1) forming that edge
3. the numeric ID of the second vertex (vi2) forming that edge

the arguments, one by one, because we don't gatekeep here 💅:

• arb — the name of the ARB primitive you want to search 🌈
• "view_x view_y view_z" — one single quoted string holding the X, Y, and Z coordinates (in view space, iykyk) that get tested against 👀
• ptol — the pick tolerance, and it's a floating point value, so bring your decimals 🍓

---

🔥 EXAMPLES 🔥

Example 1. Identify an ARB edge near a view coordinate

mged> find_arb_edge arb8.s "0 0 1" 0.5

this searches arb8.s for an edge that lands within 0.5 units of the view coordinate (0, 0, 1), then returns the edge ID plus its two vertex IDs. iconic behavior honestly ⭐
