       void glRotated( GLdouble angle,
                       GLdouble x,
                       GLdouble y,
                       GLdouble z )
       void glRotatef( GLfloat angle,

                       GLfloat y,
                       GLfloat z )

PARAMETERS

       angle  Specifies the angle of rotation, in degrees.

       x, y, z
              Specify the x, y, and z coordinates of a vector, respectively.

DESCRIPTION

       glRotate produces  a  rotation  of  angle  degrees  around  the  vector
       (x,y,z).   The  current  matrix  (see  glMatrixMode) is multiplied by a
       rotation matrix with the product replacing the current  matrix,  as  if
       glMultMatrix were called with the following matrix as its argument:

                         x2(1-c)+c  xy(1-c)-zs xz(1-c)+ys 0



















                         yx(1-c)+zs y2(1-c)+c  yz(1-c)-xs 0

























                             0          0          0      1


       Where  c=cos(angle),  s=sin(angle),  and  ||(x,y,z)||=1 (if not, the GL
       will normalize this vector).



       If the matrix mode is either GL_MODELVIEW or GL_PROJECTION, all objects
       drawn  after  glRotate  is  called  are  rotated.  Use glPushMatrix and
       glPopMatrix to save and restore the unrotated coordinate system.

NOTES

       This rotation follows the right-hand rule, so  if  the  vector  (x,y,z)
       points toward the user, the rotation will be counterclockwise.

ERRORS

       GL_INVALID_OPERATION  is  generated if glRotate is executed between the
       execution of glBegin and the corresponding execution of glEnd.
