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.
