quat_interpolate(3)

📦 version 4.4.3.1, in fedora 43, fedora 44

okay so bestie, welcome to quat_interpolate(3) from the Allegro manual — it's giving rotation interpolation, and honestly? iconic. ✨

✨ NAME ✨

  • quat_interpolate — constructs a quaternion that represents a rotation between from and to 🌀. Also: Allegro game programming library, periodt. 💖

✨ SYNOPSIS ✨

here's the vibe:

#include <allegro.h>

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

✨ DESCRIPTION ✨

So basically quat_interpolate builds a quaternion that is the rotation between from and to — like the in-between frame your main character needs for a smooth spin. 💫

The argument t can be anything between 0 and 1, and it tells you where between from and to the result lands. 0 returns from, 1 returns to, and 0.5 returns a rotation exactly in between. The result gets copied to out. 📦

this function will create the short rotation (less than 180 degrees) between from and to. no long-way-round drama, bestie. 🫶

✨ SEE ALSO ✨
