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 multiplica-
     tion is not commutative, ie. quat_mul(p, q) != quat_mul(q, p).

Allegro 			  version 4.4.3 		     quat_mul(3)
