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 def-
       inition 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 tessel-
       lated, 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);
