void GLAPIENTRY glRotatef( GLfloat angl )

PARAMETERS
       angl  Specifies the angle of rotation, in degrees.

       _param2, _param3, _param4
             Specify the x, y, and z coordinates of a vector, respectively.

DESCRIPTION
       glRotate  produces  a  rotation of angl degrees around the vector (_eqn‐
       param2,_eqnparam3,_eqnparam4).  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:
                 _eqnparam22(1−c)+c           _eqnparam2_eqnparam3(1−c)−_eqn‐
       ⎝_eqnparam3_eqnparam2(1−c)+_eqnparam4s
        _eqnparam2_eqnparam4(1−c)−_eqnparam3s
                   param4s0_eqnparam2_eqnparam4(1−c)+_eqnparam3s 0
_eqnparam32(1−c)+c           _eqnparam3_eqnparam4(1−c)−_eqnparam2s 0⎠
_eqnparam3_eqnparam4(1−c)+_eqnparam2s          _eqnparam42(1−c)+c           0
       Where  c=cos(angl),  s=sin(angl),   and   ||(_eqnparam2,_eqnparam3,_eqn‐
       param4)||=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 (_eqn‐
       param2,_eqnparam3,_eqnparam4) 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.
