<li><a href="http://www.qhull.org">Qhull Home Page</a> <p>Qhull
computes the convex hull, Delaunay triangulation, Voronoi diagram, halfspace
intersection about a point, furthest-site Delaunay
triangulation, and furthest-site Voronoi diagram. It
runs in 2-d, 3-d, 4-d, and higher dimensions. It
implements the Quickhull algorithm for computing the
convex hull. Qhull handles roundoff errors from floating
point arithmetic. It can approximate a convex hull. </p>

Qhull version 1.0</a> (92K) <p>Type: C source code for
32-bit architectures </p>
<p>Version 1.0 is a fifth the size of version 2.4. It
computes convex hulls and Delaunay triangulations. If a
precision error occurs, it stops with an error message.
It reports an initialization error for inputs made with
0/1 coordinates. </p>
<p>Version 1.0 compiles on a PC with Borland C++ 4.02 for
Win32 and DOS Power Pack. The options for rbox are
&quot;bcc32 -WX -w- -O2-e -erbox -lc rbox.c&quot;. The
options for qhull are the same. [D. Zwick] </p>
