<para>

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