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.
FORTRAN SPECIFICATION
     SUBROUTINE fglVertex2dv( CHARACTER*8 v )
     SUBROUTINE fglVertex2fv( CHARACTER*8 v )
     SUBROUTINE fglVertex2iv( CHARACTER*8 v )
     SUBROUTINE fglVertex2sv( CHARACTER*8 v )
     SUBROUTINE fglVertex3dv( CHARACTER*8 v )
     SUBROUTINE fglVertex3fv( CHARACTER*8 v )
     SUBROUTINE fglVertex3iv( CHARACTER*8 v )
     SUBROUTINE fglVertex3sv( CHARACTER*8 v )
     SUBROUTINE fglVertex4dv( CHARACTER*8 v )
     SUBROUTINE fglVertex4fv( CHARACTER*8 v )
     SUBROUTINE fglVertex4iv( CHARACTER*8 v )
     SUBROUTINE fglVertex4sv( CHARACTER*8 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
     fglVertex commands are used within fglBegin/fglEnd pairs to specify
     point, line, and polygon vertices.  The current color, normal, and
     texture coordinates are associated with the vertex when fglVertex 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 fglVertex outside of a fglBegin/fglEnd pair results in undefined
     behavior.
