💖 MATRIXCOMPMULT 💖

okay bestie, gather round, because we're about to talk about matrixCompMult from the 3G manual section, and it's genuinely so much simpler than it sounds. no cap. 🦋

✨ NAME ✨

matrixCompMult — do a component-wise multiplication of two matrices. that's it. that's the whole vibe. 💅

🌸 DECLARATION 🌸

here's the tea, exactly as written:

mat matrixCompMult(mat x, mat y);

dmat matrixCompMult(dmat x, dmat y);

two flavors, two moods, same energy. 🎀

🫶 PARAMETERS 🫶

  • x — the first matrix multiplicand. yeah she's the first one up. 👑
  • y — the second matrix multiplicand. and she's the second. iconic duo fr fr.

💀 DESCRIPTION 💀

so matrixCompMult performs a component-wise multiplication of two matrices, and what you get back is a result matrix where every single component, result[i][j], is computed as the scalar product of x[i][j] and y[i][j].

like… it's not the fancy matrix-times-matrix thing you might be picturing, bestie. it's element by element. position by position. x[i][j] times y[i][j], slotted right into result[i][j]. literally just that. and honestly? she ate. ✨

👑 VERSION SUPPORT 👑

bestie the original had a whole big grid here, so let me translate it into a format your eyeballs can actually survive. every ✘-free row, every version, all of it. no skipping. 💜

matrixCompMult (genType) — supported in every single one of these, she's been here since day one:

  • OpenGL Shading Language Version 1.10 — ✔
  • OpenGL Shading Language Version 1.20 — ✔
  • OpenGL Shading Language Version 1.30 — ✔
  • OpenGL Shading Language Version 1.40 — ✔
  • OpenGL Shading Language Version 1.50 — ✔
  • OpenGL Shading Language Version 3.30 — ✔
  • OpenGL Shading Language Version 4.00 — ✔
  • OpenGL Shading Language Version 4.10 — ✔
  • OpenGL Shading Language Version 4.20 — ✔
  • OpenGL Shading Language Version 4.30 — ✔
  • OpenGL Shading Language Version 4.40 — ✔
  • OpenGL Shading Language Version 4.50 — ✔

matrixCompMult (genDType) — the double-precision girlie showed up fashionably late, but she's been thriving ever since:

  • OpenGL Shading Language Version 1.10 — -
  • OpenGL Shading Language Version 1.20 — -
  • OpenGL Shading Language Version 1.30 — -
  • OpenGL Shading Language Version 1.40 — -
  • OpenGL Shading Language Version 1.50 — -
  • OpenGL Shading Language Version 3.30 — -
  • OpenGL Shading Language Version 4.00 — ✔
  • OpenGL Shading Language Version 4.10 — ✔
  • OpenGL Shading Language Version 4.20 — ✔
  • OpenGL Shading Language Version 4.30 — ✔
  • OpenGL Shading Language Version 4.40 — ✔
  • OpenGL Shading Language Version 4.50 — ✔

so basically: genType = always been there, genDType = 4.00 and onward only. iykyk. 🌈
