PUT_COMB(nged)

💅 PUT_COMB(nged) — like, the MGED command, bestie

okay so we're in the BRL-CAD MGED Commands manual, and the star of the show today is put_comb. pull up a chair 🎀

---

✨ NAME ✨

put_comb — insert combinations and regions 💖 it lets you define both boolean expressions and standard attribute values. one command. that's it. that's the whole vibe.

---

🦋 SYNOPSIS 🦋

put_comb {comb_name} [is_Region  [[id] | [air] | [material] | [los]]] {color} {shader} {inherit} {boolean_expr}

(yes there are two spaces after is_Region, no we're not fixing it, it's iconic 💅)

---

🌸 DESCRIPTION 🌸

So put_comb is THE command for inserting regions and combinations with all their attributes set — using just one single line 🔥 which is genuinely so useful in scripting situations. like, scripting girlies, this one's for you 🫶

---

👑 EXAMPLES 👑

put_comb expects one of two particular forms of input, bestie — either a combination or a region. pick your fighter ✨

💜 Example 1. Specifying a combination using put_comb

mged>put_comb test.c n 255/255/255 plastic n "u sph.s u arb8.s"

This creates a combination that is not a region, using the plastic shader, consisting of the union of sph.s and arb8.s. 💫

    mged> l test.c
    test.c:  --
    Shader 'plastic'
       u sph.s
       u arb8.s
    mged> attr get test.c
    oshader {plastic}

🍓 Example 2. Specifying a region using put_comb

mged>put_comb test.r y 1001 0 32 1 255/255/255 plastic y "u sph.s u
arb8.s"

This creates a combination that is a region, with region id 1001, air flag off, material 32, los 1, white in color, using the plastic shader, inheriting, consisting of the union of sph.s and arb8.s. no cap 👑

    mged> l test.r
    test.r:  REGION id=1001 (air=0, los=1, GIFTmater=32) --
    Shader 'plastic'
    (These material properties override all lower ones in the tree)
       u sph.s
       u arb8.s
    mged> attr get test.r
    region {R} inherit {1} oshader {plastic} region_id {1001}
    material_id {32} los {1}

ngl that attribute dump is kind of a serve 💅
