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 mul‐
       tiplication is not commutative, ie. quat_mul(p, q) != quat_mul(q, p).
