quat_interpolate(3alleg4)

💫 quat_interpolate — the Allegro manual, but make it make sense 💫

okay bestie, gather round, because we're talking about quat_interpolate from the Allegro game programming library, and honestly? she's a little icon. 🌸

✨ NAME ✨

quat_interpolate — builds you a quaternion that reps a rotation sitting somewhere between from and to. it's giving Allegro game programming library, no cap. 💅

🎀 SYNOPSIS 🎀

#include <allegro.h>

void quat_interpolate(const QUAT *from, const QUAT *to, float t, QUAT
*out);

🦋 DESCRIPTION 🦋

so here's the tea 🫖 — this function constructs a quaternion that represents a rotation between from and to.

that t argument? she can be anything between 0 and 1, and she tells you where between from and to your result is gonna land:

• 0 → returns from
• 1 → returns to
• 0.5 → returns a rotation that's exactly in between ✨

the result gets copied into out. and the best part, lowkey the main character move: this function will create the short rotation (less than 180 degrees) between from and to. slay. 👑

ngl, that short-rotation thing is the whole vibe — she's not gonna take the long way around the sphere, periodt.
