quat_mul(3)                     Allegro manual                     quat_mul(3)



NAME
       quat_mul - Multiplies two quaternions. Allegro game programming
       library.

SYNOPSIS
       #include <allegro.h>


       void quat_mul(const QUAT *p, const QUAT *q, QUAT *out);

DESCRIPTION
       Multiplies two quaternions, storing the result in out. The resulting
       quaternion will have the same effect as the combination of p and q, ie.
       when applied to a point, (point * out) = ((point * p) * q). Any number
       of rotations can be concatenated in this way. Note that quaternion
       multiplication is not commutative, ie. quat_mul(p, q) != quat_mul(q,
       p).
