💖 LESSTHANEQUAL 💖

okay bestie, sit down, we're talking about lessThanEqual from the OpenGL Shading Language family (the 3G manual, GLSL squad represent ✨). it's a teeny tiny comparison function and it's lowkey iconic.

🌸 NAME 🌸

lessThanEqual — does a component-wise less-than-or-equal comparison of two vectors. that's it. that's the whole vibe. 💅

✨ DECLARATION ✨

here's the exact glow-up, no cap:

bvec lessThanEqual(vec x, vec y);

bvec lessThanEqual(ivec x, ivec y);

bvec lessThanEqual(uvec x, uvec y);

three overloads, three moods. 🦋

🎀 PARAMETERS 🎀

  • x — the first vector in the comparison operation. your opening act. the main character. 👑
  • y — the second vector in the comparison operation. the one x gets compared against. 🫶

💜 DESCRIPTION 💜

lessThanEqual returns a boolean vector, and each element i in it is computed as:

x[i] ≤ y[i]

so like… element by element, bestie. it's giving "are you less than or equal to me or not" and the answer comes back as true/false for every single slot. no skips, no shortcuts, every component gets its moment. ✨

🔥 VERSION SUPPORT 🔥

here's the whole availability timeline, and yes i'm listing every single version because we do not skip data in this house. the GLSL versions we're checking against are 1.10, 1.20, 1.30, 1.40, 1.50, 3.30, 4.00, 4.10, 4.20, 4.30, 4.40 and 4.50. 🌈

  • lessThanEqual (uvec) — - in 1.10, - in 1.20, then ✔ in 1.30, ✔ in 1.40, ✔ in 1.50, ✔ in 3.30, ✔ in 4.00, ✔ in 4.10, ✔ in 4.20, ✔ in 4.30, ✔ in 4.40, ✔ in 4.50. she was late to the party but she showed up and she slayed. 😭
ngl the uvec version didn't exist yet in 1.10 and 1.20 — that's what those little dashes mean. don't go looking for it there, bestie, it's not there. 💀
