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.
