		   GLdouble w )
  void glVertex4f( GLfloat x,
		   GLfloat y,
		   GLfloat z,
		   GLfloat w )
  void glVertex4i( GLint x,
		   GLint y,
		   GLint z,
		   GLint w )
  void glVertex4s( GLshort x,
		   GLshort y,
		   GLshort z,
		   GLshort w )

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 elements.	 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 0.0 and w defaults to 1.0.
  When x, y, and z are specified, w defaults to	1.0.

Notes

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