GLROTATE(3G)															      GLROTATE(3G)

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:

							   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)
							   xz(1-c)-ys yz(1-c)+xs z2(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.
