NAME

       get_align_matrix  -  Rotates  a  matrix  to  align  it along specified coordinate vectors.
       Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       void get_align_matrix(MATRIX *m, fixed xfront, yfront, zfront, fixed xup, fixed yup, fixed
       zup);

DESCRIPTION

       Rotates  a  matrix so that it is aligned along the specified coordinate vectors (they need
       not be normalized or perpendicular, but the up and front  must  not  be  equal).  A  front
       vector of 0,0,-1 and up vector of 0,1,0 will return the identity matrix.
