NAME

       quat_interpolate  -  Constructs  a  quaternion  representing a rotation between from and to. Allegro game
       programming library.

SYNOPSIS

       #include <allegro.h>

       void quat_interpolate(const QUAT *from, const QUAT *to, float t, QUAT *out);

DESCRIPTION

       Constructs a quaternion that represents a rotation between from and to.  The argument t can  be  anything
       between  0  and  1 and represents where between from and to the result will be. 0 returns from, 1 returns
       to, and 0.5 will return a rotation exactly in between. The result is copied to out.  This  function  will
       create the short rotation (less than 180 degrees) between from and to.
