glRotate(3)                                                      glRotate(3)




NAME

       glRotated, glRotatef - multiply the current matrix by a rotation matrix



C SPECIFICATION

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


         x^2(1-c)+c     xy(1-c)-zs     xz(1-c)+ys     0
         yx(1-c)+zs     y^2(1-c)+c     yz(1-c)-xs     0
         xz(1-c)-ys     yz(1-c)+xs     z^2(1-c)+c     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.
