get_rotation_matrix(3alleg4)     Allegro manual     get_rotation_matrix(3alleg4)



NAME
       get_rotation_matrix, get_rotation_matrix_f - Constructs X, Y, Z rotation
       matrices. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>


       void get_rotation_matrix(MATRIX *m, fixed x, fixed y, fixed z);

       void get_rotation_matrix_f(MATRIX_f *m, float x, float y, float z);

DESCRIPTION
       Constructs a transformation matrix which will rotate points around all
       three axes by the specified amounts (given in binary, 256 degrees to a
       circle format). The direction of rotation can simply be found out with
       the right-hand rule: Point the dumb of your right hand towards the origin
       along the axis of rotation, and the fingers will curl in the positive
       direction of rotation. E.g. if you rotate around the y axis, and look at
       the scene from above, a positive angle will rotate in clockwise
       direction.
