apply_quat(3)			 Allegro manual 		   apply_quat(3)

NAME
     apply_quat  -  Multiplies a point by a quaternion. Allegro game programming
     library.

SYNOPSIS
     #include <allegro.h>

     void apply_quat(const QUAT *q, float x, y, z, *xout, *yout, *zout);

DESCRIPTION
     Multiplies the point (x, y, z) by the quaternion q, storing the  result  in
     (*xout, *yout, *zout). This is quite a bit slower than apply_matrix_f(), so
     only  use it to translate a few points. If you have many points, it is much
     more efficient to call quat_to_matrix() and then use apply_matrix_f().
