     <STRONG>PARAMETERS</STRONG>
	  <EM>nx</EM>, <EM>ny</EM>, <EM>nz</EM>
		    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).

     <STRONG>C</STRONG> <STRONG>SPECIFICATION</STRONG>
	  void <STRONG>glNormal3bv</STRONG>( const GLbyte *<EM>v</EM> )
	  void <STRONG>glNormal3dv</STRONG>( const GLdouble *<EM>v</EM> )
	  void <STRONG>glNormal3fv</STRONG>( const GLfloat *<EM>v</EM> )
	  void <STRONG>glNormal3iv</STRONG>( const GLint	*<EM>v</EM> )
	  void <STRONG>glNormal3sv</STRONG>( const GLshort *<EM>v</EM> )


     <STRONG>PARAMETERS</STRONG>
	  <EM>v</EM>    Specifies a pointer to an array of three	elements:  the
	       x, y, and z coordinates of the new current normal.

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

	  Normals specified with <STRONG>glNormal</STRONG> need not have	unit length.
	  If normalization is enabled, then normals specified with
	  <STRONG>glNormal</STRONG> are normalized after	transformation.	 To enable and
	  disable normalization, call <STRONG>glEnable</STRONG> and <STRONG>glDisable</STRONG> with the
	  argument <STRONG>GL_NORMALIZE</STRONG>.  Normalization	is initially disabled.

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

     <STRONG>ASSOCIATED</STRONG>	<STRONG>GETS</STRONG>
	  <STRONG>glGet</STRONG>	with argument <STRONG>GL_CURRENT_NORMAL</STRONG>
	  <STRONG>glIsEnabled</STRONG> with argument <STRONG>GL_NORMALIZE</STRONG>
