three-dimensional scenes into static drawings. This version generates

<p><a name="index-polygon-265"></a><strong>Syntax:</strong>
<pre class="example">     polygon[<var>options</var>] <var>point_list</var>
</pre>
   <p class="noindent">This command is the three-dimensional equivalent of the
<code>PSTricks</code> command <code>\pspolygon</code>.  The <code>sketch</code> hidden
surface algorithm assumes that polygons are convex and planar. 
<a name="index-polygon_002c-planar-266"></a><a name="index-planarity-of-polygons-267"></a>In practice, drawings may well turn out correctly even if these
assumptions are violated.
