WHICH_SHADER(nged)

💅 WHICH_SHADER 💅 (nged)

okay bestie, so you know how your database has a million combinations and you're sitting there like "which ones are using that one shader??" 😭 yeah. this is the manual page for which_shader, a BRL-CAD User Command, and it exists to save you from that exact spiral 🫶

---

✨ NAME ✨

which_shader — literally lists, for you, every single combination that's using a given shader 💖

🎀 SYNOPSIS 🎀

which_shader [-s] shader_name(s)

🌸 DESCRIPTION 🌸

so here's the vibe: which_shader goes digging through every combination in the database and reports back the ones whose shader string contains one or more of the shader_name values you gave it. it's a substring match, no cap — a combination gets included as long as its shader field has the given name anywhere inside it. slay. 🔥

heads up though: only combinations get scanned. primitive shapes don't have shaders, so they're not even checked. sorry not sorry to the primitives 💀

and yes, you can hand it multiple shader names at once — it just scans the database once for each one. efficient queen behavior 👑

⭐ Options ⭐

• -s — script mode! it spits out the matching combination names separated by spaces, all on a single line, no headers, ngl super clean for automation. without this flag, the output gets grouped under a heading for each shader name, with each matching combination chillin' on its own indented line 🦋

🌈 EXAMPLES 🌈

Example 1. list all combinations using the plastic shader

mged> which_shader plastic

this reports all combinations whose shader string contains plastic, with a heading line and one name per line ✨

example output, iconically:

Combination[s] with shader plastic:
   hull.c
   turret.c

Example 2. script-mode output for use in automation

mged> which_shader -s plastic

returns the matching names space-separated, no header, for use in scripts 🎀

hull.c turret.c

Example 3. search for multiple shaders at once

mged> which_shader plastic glass

scans for combinations using plastic, then separately for ones using glass, and reports the results under their own separate headings. multitasking main character energy fr fr 💅
