quat_slerp(3)

✨ NAME ✨

okay so bestie, this is the quat_slerp(3) page from the Allegro manual 💖 It's literally the version of quat_interpolate() that lets you control the rotation. And yes, it's part of the Allegro game programming library. Periodt.

🦋 SYNOPSIS 🦋

here's the exact incantation, no cap:

       #include <allegro.h>

       void quat_slerp(const QUAT *from, const QUAT *to, float t, QUAT *out,
       int how);

💅 DESCRIPTION 💅

So this is the same as quat_interpolate(), but it allows more control over how the rotation is done. The how parameter can be any one of these iconic values:

• QUAT_SHORT — like quat_interpolate(), use shortest path 🛣️
• QUAT_LONG — rotation will be greater than 180 degrees 🔄
• QUAT_CW — rotate clockwise when viewed from above 🕐
• QUAT_CCW — rotate counterclockwise when viewed from above 🔄
• QUAT_USER — the quaternions are interpolated exactly as given 🎯

Allegro version 4.4.3, quat_slerp(3), and no date in the footer — bye bestie, go rotate something cute 💖🦋
