Within each <STRONG>gluTessBeginContour</STRONG>/<STRONG>gluTessEndContour</STRONG> pair, there can be zero or more calls to <STRONG>gluTessVertex</STRONG>. The vertices specify a closed contour (the last vertex of each contour is automatically linked to the first). See the <STRONG>gluTessVertex</STRONG> reference page for more details. <STRONG>gluTessBeginContour</STRONG> can only be called between <STRONG>gluTessBeginPolygon</STRONG> and <STRONG>gluTessEndPolygon</STRONG>. <STRONG>SEE</STRONG> <STRONG>ALSO</STRONG> <STRONG>gluNewTess</STRONG>, <STRONG>gluTessBeginPolygon</STRONG>, <STRONG>gluTessVertex</STRONG>, <STRONG>gluTessCallback</STRONG>, <STRONG>gluTessProperty</STRONG>, <STRONG>gluTessNormal</STRONG>, <STRONG>gluTessEndPolygon</STRONG> </PRE> </BODY> </HTML>
