LENGTH(3G) 💖

okay bestie, welcome to LENGTH(3G) — the glow-up era of vector math ✨ this one lives in the 3G manual section and it's literally just vibes about how long a vector is. no cap.

NAME 🎀

length — calculate the length of a vector

DECLARATION 📜

here's the tea, the actual signatures, copy them exactly bestie:

float length(genType x);

double length(genDType x);

PARAMETERS 🌸

  • x — the vector you want the length of. that's it. that's the whole assignment. hand it over and it gets measured. 💅

DESCRIPTION 🦋

length returns the length of the vector, i.e. $\sqrt { { x[0] }^2 + { x[1] }^2 + \dots }$.

so yeah, it's squaring every component, adding them all up, and square-rooting the whole situation. iconic behavior honestly. 🧮✨

VERSION SUPPORT 👑

the vibe check on which OpenGL Shading Language versions said yes to this function. here's the chart, un-tabled for your scrolling pleasure:

length (genType) — supported everywhere, no skips:

  • 1.10 — ✔
  • 1.20 — ✔
  • 1.30 — ✔
  • 1.40 — ✔
  • 1.50 — ✔
  • 3.30 — ✔
  • 4.00 — ✔
  • 4.10 — ✔
  • 4.20 — ✔
  • 4.30 — ✔
  • 4.40 — ✔
  • 4.50 — ✔

length (genDType) — late bloomer era, showed up fashionably late at 4.00:

  • 1.10 — -
  • 1.20 — -
  • 1.30 — -
  • 1.40 — -
  • 1.50 — -
  • 3.30 — -
  • 4.00 — ✔
  • 4.10 — ✔
  • 4.20 — ✔
  • 4.30 — ✔
  • 4.40 — ✔
  • 4.50 — ✔
ngl the genDType row is giving "arrived at the party at 4.00" energy and we respect the journey 🫶
