gluTessBeginContour, gluTessEndContour - delimit a contour
       description



C SPECIFICATION

       void gluTessBeginContour( GLUtesselator* tess )

       void gluTessEndContour( GLUtesselator* tess )



PARAMETERS

       tess  Specifies  the  tessellation  object  (created  with
             gluNewTess).


DESCRIPTION

       gluTessBeginContour and gluTessEndContour delimit the def-
       inition   of    a    polygon    contour.    Within    each
       gluTessBeginContour/gluTessEndContour  pair,  there can be
       zero or more calls to gluTessVertex. The vertices  specify
       a closed contour (the last vertex of each contour is auto-
       matically linked to the  first).   See  the  gluTessVertex
       reference  page for more details.  gluTessBeginContour can
       only   be   called   between    gluTessBeginPolygon    and
       gluTessEndPolygon.
