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-ele-
              ment 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.
