<p>These sections describe the options for Qhull. This section
lists the main options. It includes the options for convex hulls
and halfspace intersections.</p>
<p>For an example of Qhull, the following computes the convex
hull of the vertices of a hypercube. It returns the facet
normals.</p>
<blockquote>
<p><tt>rbox c D4 | qhull n</tt></p>
</blockquote>
<p>See <a href="qh-man.htm#synopsis">Synopsis and examples</a>
and <a href="qh-eg.htm">Qhull examples</a> for more examples.
Execute <tt>'qhull'</tt> by itself for a synopsis and list of
examples. To get the full list of options, execute <tt>'qhull - |
more'</tt>. To get a concise list of all options, execute <tt>'qhull
.'</tt>.</p>
<p>There are many options. The best way to learn an option is to
try it with small examples. Use <a href="qh-rbox.htm">rbox</a> to
generate input sets. If you have Unix, use <a
href="qh-man.htm#geomview">Geomview</a> to view the results.
Start with the following input sets:</p>
<ul>
<li><tt>'rbox c</tt>' generates a cube. The facets are
non-simplicial.</li>
<li><tt>'rbox d</tt>' generates a diamond. The facets are
simplicial.</li>
<li><tt>'rbox 6</tt>' generates 6 random points.</li>
</ul>
