current normal vector

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 nor-
                 mal.  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
        with a linear mapping that maps the most positive representable  inte-
       ger  value to 1.0, and the most negative representable integer value to
       -1.0.

       Normals  specified  with  glNormal  need  not  have  unit  length.   If
       GL_NORMALIZE  is  enabled,  then  normals  of any length specified with
       glNormal are normalized after transformation.  If GL_RESCALE_NORMAL  is
       glIsEnabled with argument GL_NORMALIZE
       glIsEnabled with argument GL_RESCALE_NORMAL
