PARAMETERS
       x, y, z, w
		Specify	 x,  y,	 z,  and  w coordinates of a vertex.  Not all
		parameters are present in all forms of the command.

C SPECIFICATION
       void glVertex2dv( const GLdouble *v )
       void glVertex2fv( const GLfloat *v )
       void glVertex2iv( const GLint *v )
       void glVertex2sv( const GLshort *v )
       void glVertex3dv( const GLdouble *v )
       void glVertex3fv( const GLfloat *v )
       void glVertex3iv( const GLint *v )
       void glVertex3sv( const GLshort *v )
       void glVertex4dv( const GLdouble *v )
       void glVertex4fv( const GLfloat *v )
       void glVertex4iv( const GLint *v )
       void glVertex4sv( const GLshort *v )


PARAMETERS
       v      Specifies a pointer to an array of two,  three,  or  four	 ele-
	      ments.   The  elements of a two-element array are x and y; of a
	      three-element array, x, y, and z; and of a four-element  array,
	      x, y, z, and w.

DESCRIPTION
       glVertex	 commands  are	used  within  glBegin/glEnd  pairs to specify
       point, line, and polygon vertices.  The	current	 color,	 normal,  and
       texture	coordinates  are  associated with the vertex when glVertex is
       called.

       When only x and y are specified, z defaults to 0 and w defaults to  1.
       When x, y, and z are specified, w defaults to 1.

NOTES
       Invoking glVertex outside of a glBegin/glEnd pair results in undefined
       behavior.
