fgluTessBeginContour(3G)

NAME
     fgluTessBeginContour, fgluTessEndContour - delimit a contour description


FORTRAN SPECIFICATION
     SUBROUTINE fgluTessBeginContour( CHARACTER*8 tess )

     SUBROUTINE fgluTessEndContour( CHARACTER*8 tess )


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

DESCRIPTION
     fgluTessBeginContour and fgluTessEndContour delimit the definition of a
     polygon contour. Within each fgluTessBeginContour/fgluTessEndContour
     pair, there can be zero or more calls to fgluTessVertex. The vertices
     specify a closed contour (the last vertex of each contour is
     automatically linked to the first).  See the fgluTessVertex reference
     page for more details.  fgluTessBeginContour can only be called between
     fgluTessBeginPolygon and fgluTessEndPolygon.
