50 <function>gluTessBeginContour
</function> and
<citerefentry><refentrytitle>gluTessEndContour
</refentrytitle></citerefentry> delimit the definition of a
51 polygon contour. Within each
<function>gluTessBeginContour
</function>/
<citerefentry><refentrytitle>gluTessEndContour
</refentrytitle></citerefentry>
52 pair, there can be zero or more calls to
<citerefentry><refentrytitle>gluTessVertex
</refentrytitle></citerefentry>. The vertices
53 specify a closed contour (the last vertex of each contour is automatically linked
54 to the first). See the
<citerefentry><refentrytitle>gluTessVertex
</refentrytitle></citerefentry> reference page for more details.
55 <function>gluTessBeginContour
</function> can only be called between
<citerefentry><refentrytitle>gluTessBeginPolygon
</refentrytitle></citerefentry> and
<citerefentry><refentrytitle>gluTessEndPolygon
</refentrytitle></citerefentry>.
