GLROTATE(3gl)							 GLROTATE(3gl)

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:
			    xx(1−c)+cxy(1−c)−zxz(1−c)+y0

			   yx(1−c)+zyy(1−c)+cyz(1−c)−xs0

			   ⎝				⎠

			  xz(1−c)−yyz(1−c)+xzz(1−c)+c  0

			      0	       0	0      1

       Where c=cos(angle), s=sine(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.

ASSOCIATED GETS
       glGet with argument GL_MATRIX_MODE
       glGet with argument GL_MODELVIEW_MATRIX
       glGet with argument GL_PROJECTION_MATRIX
       glGet with argument GL_TEXTURE_MATRIX
