NAME
       gluTessEndPolygon - delimit a polygon description


C SPECIFICATION
       void gluTessEndPolygon( GLUtesselator* tess )


PARAMETERS
       tess  Specifies the tessellation object (created with gluNewTess).

DESCRIPTION
       gluTessBeginPolygon  and gluTessEndPolygon delimit the definition of a
       convex,	 concave   or	self-intersecting   polygon.   Within	 each
       gluTessBeginPolygon/gluTessEndPolygon  pair, there must be one or more
       calls to gluTessBeginContour/gluTessEndContour.	Within each  contour,
       there  are zero or more calls to gluTessVertex. The vertices specify a
       closed contour (the last	 vertex	 of  each  contour  is	automatically
       linked  to  the first). See the gluTessVertex, gluTessBeginContour and
       gluTessEndContour reference pages for more details.

       Once gluTessEndPolygon is called, the polygon is tessellated, and  the
       resulting    triangles	are   described	  through   callbacks.	  See
       gluTessCallback for descriptions of the callback functions.

EXAMPLE
       A quadrilateral with a triangular hole in it  can  be  described	 like
       this:

       gluTessBeginPolygon(tobj, NULL);
	gluTessBeginContour(tobj);
	  gluTessVertex(tobj, v1, v1);
	  gluTessVertex(tobj, v2, v2);
	  gluTessVertex(tobj, v3, v3);
	  gluTessVertex(tobj, v4, v4);
	gluTessEndContour(tobj);
	gluTessBeginContour(tobj);
	  gluTessVertex(tobj, v5, v5);
	  gluTessVertex(tobj, v6, v6);
	  gluTessVertex(tobj, v7, v7);
	gluTessEndContour(tobj); gluTessEndPolygon(tobj);





















       In the above example the pointers, v1 through v7, should point to dif-
       ferent addresses, since the values stored at these addresses will  not
       be read by the tesselator until gluTessEndPolygon is called.
