GLNORMAL()							    GLNORMAL()

NAME
       glNormal3b,  glNormal3d,	 glNormal3f,  glNormal3i,  glNormal3s,	glNor-
       mal3bv, glNormal3dv, glNormal3fv, glNormal3iv, glNormal3sv  -  set  the
       current normal vector

       delim $$

C SPECIFICATION
       void glNormal3b(	GLbyte nx,
			GLbyte ny,
			GLbyte nz )
       void glNormal3d(	GLdouble nx,
			GLdouble ny,
			GLdouble nz )
       void glNormal3f(	GLfloat	nx,
			GLfloat	ny,
			GLfloat	nz )
       void glNormal3i(	GLint nx,
			GLint ny,
			GLint nz )
       void glNormal3s(	GLshort	nx,
			GLshort	ny,
			GLshort	nz )

PARAMETERS
       nx, ny, nz
		 Specify  the $x$, $y$,	and $z$	coordinates of the new current
		 normal.  The initial value of the current normal is the  unit
		 vector, (0, 0,	1).

C SPECIFICATION
       void glNormal3bv( const GLbyte *v )
       void glNormal3dv( const GLdouble	*v )
       void glNormal3fv( const GLfloat *v )
       void glNormal3iv( const GLint *v	)
       void glNormal3sv( const GLshort *v )

PARAMETERS
       v      Specifies	a pointer to an	array of three elements: the $x$, $y$,
	      and $z$ coordinates of the new current normal.

DESCRIPTION
       The current normal is set to the	given coordinates whenever glNormal is
       issued.	 Byte,	short, or integer arguments are	converted to floating-
       point format with a linear mapping that maps the	most  positive	repre-
       sentable	 integer value to 1.0, and the most negative representable in-
       teger value to -1.0.

       Normals specified with glNormal need not	have unit length.  If  normal-
       ization is enabled, then	normals	specified with glNormal	are normalized
       after  transformation.  To enable and disable normalization, call glEn-
       able and	glDisable with the argument  GL_NORMALIZE.   Normalization  is
       initially disabled.

NOTES
       The current normal can be updated at any	time.  In particular, glNormal
       can  be	called between a call to glBegin and the corresponding call to
       glEnd.

ASSOCIATED GETS
       glGet with argument GL_CURRENT_NORMAL
       glIsEnabled with	argument GL_NORMALIZE
