NAME

       get_x_rotate_quat,  get_y_rotate_quat,  get_z_rotate_quat  - Construct axis rotation quaternions. Allegro
       game programming library.

SYNOPSIS

       #include <allegro.h>

       void get_x_rotate_quat(QUAT *q, float r);

       void get_y_rotate_quat(QUAT *q, float r);

       void get_z_rotate_quat(QUAT *q, float r);

DESCRIPTION

       Construct axis rotation quaternions, storing them in q. When applied to a point, these  quaternions  will
       rotate  it  about  the  relevant  axis  by  the specified angle (given in binary, 256 degrees to a circle
       format).
