Within each \%\f3gluTessBeginContour\fP/\%\f3gluTessEndContour\fP pair, there can be zero or more calls to \%\f3gluTessVertex\fP. The vertices specify a closed contour (the last vertex of each contour is automatically linked to the first). See the \%\f3gluTessVertex\fP reference page for more details. \%\f3gluTessBeginContour\fP can only be called between \%\f3gluTessBeginPolygon\fP and \%\f3gluTessEndPolygon\fP. .SH SEE ALSO \%\f3gluNewTess(3G)\fP, \%\f3gluTessBeginPolygon(3G)\fP, \%\f3gluTessVertex(3G)\fP, \%\f3gluTessCallback(3G)\fP, \%\f3gluTessProperty(3G)\fP, \%\f3gluTessNormal(3G)\fP, \%\f3gluTessEndPolygon\fP
