It 25 runs in 2-d, 3-d, 4-d, and higher dimensions. It 26 implements the Quickhull algorithm for computing the 27 convex hull. Qhull handles roundoff errors from floating 28 point arithmetic. It can approximate a convex hull. </p> 29 30 <p>Visit <a href="http://www.qhull.org/news">Qhull News</a> 31 for news, bug reports, change history, and users. 32 If you use Qhull 2003.1 or 2009.1, please upgrade or apply 33 <a href="http://www.qhull.org/download/poly.c-qh_gethash.patch">poly.c-qh_gethash.patch</a>.</p> 34 </li> 35 <li><a 36 href="http://www.qhull.org/download/qhull-2020.2.zip">Download: 37 Qhull 2020.2 for Windows 10, 8, 7, XP, and NT</a> (3.3 MB, 38 <a href="http://www.qhull.org/README.txt">readme</a>, 39 <a href="http://www.qhull.org/download/qhull-2020.2.md5sum">md5sum</a>, 40 <a href="http://www.qhull.org/download/qhull-2020.2-zip.md5sum">contents</a>) 41 <p>Type: console programs for Windows (32- or 64-bit)</p> 42 <p>Includes 32-bit executables, documentation, and sources files.

83Type: C source code for 84 32-bit architectures </p> 85 <p>Version 1.0 is a fifth the size of version 2.4. It 86 computes convex hulls and Delaunay triangulations. If a 87 precision error occurs, it stops with an error message. 88 It reports an initialization error for inputs made with 89 0/1 coordinates. </p> 90 <p>Version 1.0 compiles on a PC with Borland C++ 4.02 for 91 Win32 and DOS Power Pack. The options for rbox are 92 "bcc32 -WX -w- -O2-e -erbox -lc rbox.c". The 93 options for qhull are the same. [D.
