+
+Qhull computes convex hulls, Delaunay triangulations, Voronoi diagrams,
+furthest-site Voronoi diagrams, and halfspace intersections about a point.
+It runs in 2-d, 3-d, 4-d, or higher.  It implements the Quickhull algorithm
+for computing convex hulls.   Qhull handles round-off errors from floating
+point arithmetic.  It can approximate a convex hull.
+
+The program includes options for hull volume, facet area, partial hulls,
+input transformations, randomization, tracing, multiple output formats, and
+execution statistics.  The program can be called from within your application.
+You can view the results in 2-d, 3-d and 4-d with Geomview.

+Abstract:
+
+The convex hull of a set of points is the smallest convex set that contains
+the points.  This article presents a practical convex hull algorithm that
+combines the two-dimensional Quickhull Algorithm with  the general dimension
+Beneath-Beyond Algorithm.  It is similar to the randomized, incremental
+algorithms for convex hull and Delaunay triangulation.  We provide empirical
+evidence that the algorithm runs faster when the input contains non-extreme
+points, and that it uses less memory.
+
+Computational geometry algorithms have traditionally assumed that input sets
+are well behaved.  When an algorithm is implemented with floating point
+arithmetic, this assumption can lead to serious errors.  We briefly describe
+a solution to this problem when computing the convex hull in two, three, or
+four dimensions.  The output is a set of "thick" facets that contain all
+possible exact convex hulls of the input.   A variation is effective in five
+or more dimensions.

+
+     Version 1 (simplicial only):
+        <http://www.qhull.org/download/qhull-1.0.tar.gz>
+       
+Purpose
+
+  Qhull is a general dimension convex hull program that reads a set 
+  of points from stdin, and outputs the smallest convex set that contains 
+  the points to stdout.  It also generates Delaunay triangulations, Voronoi 
+  diagrams, furthest-site Voronoi diagrams, and halfspace intersections
+  about a point.
+
+  Rbox is a useful tool in generating input for Qhull; it generates 
+  hypercubes, diamonds, cones, circles, simplices, spirals, 
+  lattices, and random points.
+  
+  Qhull produces graphical output for Geomview.  This helps with
+  understanding the output. <http://www.geomview.org>
+
+Environment requirements
+
+  Qhull and rbox should run on all 32-bit and 64-bit computers.  Use
+  an ANSI C or C++ compiler to compile the program.  The software is 
+  self-contained.  It comes with examples and test scripts.
+  
+  Qhull's C++ interface uses the STL.  The C++ test program uses QTestLib 
+  from the Qt Framework.  Qhull's C++ interface may change without 
+  notice.  Eventually, it will move into the qhull shared library.
+  
+  Qhull is copyrighted software.  Please read COPYING.txt and REGISTER.txt
+  before using or distributing Qhull.
+
+To cite Qhull, please use

+  Barber, C.B., Dobkin, D.P., and Huhdanpaa, H.T., "The Quickhull 
+  algorithm for convex hulls," ACM Trans. on Mathematical Software,
+  22(4):469-483, Dec 1996, http://www.qhull.org.
+
+To modify Qhull, particularly the C++ interface
+
+  Qhull is on GitHub 
+     (http://github.com/qhull/qhull, git@github.com:qhull/qhull.git)
+  
+  For internal documentation, see html/qh-code.htm
+
+To install Qhull
+
+  Qhull is precompiled for Windows 32-bit, otherwise it needs compilation.
+  
+  Qhull includes Makefiles for gcc and other targets, CMakeLists.txt for CMake,
+  .sln/.vcproj/.vcxproj files for Microsoft Visual Studio, and .pro files 
+  for Qt Creator.  It compiles under Windows with mingw.
+  
+  Install and build instructions follow.  
+  
+  See the end of this document for a list of distributed files.
+
+-----------------
+Installing Qhull on Windows 10, 8, 7 (32- or 64-bit), Windows XP, and Windows NT
+
+  The zip file contains rbox.exe, qhull.exe, qconvex.exe, qdelaunay.exe, 
+  qhalf.exe, qvoronoi.exe, testqset.exe, user_eg*.exe, documentation files, 
+  and source files.  Qhull.exe and user-eg3.exe are compiled with the reentrant 
+  library while the other executables use the non-reentrant library.
+  
+  To install Qhull:
+  - Unzip the files into a directory (e.g., named 'qhull')
+  - Click on QHULL-GO or open a command window into Qhull's bin directory.
+  - Test with 'rbox D4 | qhull'
+    
+  To uninstall Qhull
+  - Delete the qhull directory
+  
+  To learn about Qhull:
+  - Execute 'qconvex' for a synopsis and examples.
+  - Execute 'rbox 10 | qconvex' to compute the convex hull of 10 random points.
+  - Execute 'rbox 10 | qconvex i TO file' to write results to 'file'.
+  - Browse the documentation: qhull\html\index.htm
+  - If an error occurs, Windows sends the error to stdout instead of stderr.
+    Use 'TO xxx' to send normal output to xxx
+
+  To improve the command window
+  - Double-click the window bar to increase the size of the window
+  - Right-click the window bar
+  - Select Properties
+  - Check QuickEdit Mode
+    Select text with right-click or Enter
+    Paste text with right-click
+  - Change Font to Lucinda Console
+  - Change Layout to Screen Buffer Height 999, Window Size Height 55
+  - Change Colors to Screen Background White, Screen Text Black
+  - Click OK
+  - Select 'Modify shortcut that started this window', then OK
+
+  If you use qhull a lot, install a bash shell such as
+    MSYS (www.mingw.org/wiki/msys), Road Bash (www.qhull.org/bash), 
+    or Cygwin (www.cygwin.com).
+
+-----------------
+Installing Qhull on Unix with gcc
+
+  To build Qhull, static libraries, shared library, and C++ interface
+  - Download and extract Qhull (either GitHub, .tgz file, or .zip file)
+  - make
+  - export LD_LIBRARY_PATH=$PWD/lib:$LD_LIBRARY_PATH
+
+  The Makefiles may be edited for other compilers.
+  If 'testqset' exits with an error, qhull is broken
+  
+  A simple Makefile for Qhull is in src/libqhull and src/libqhull_r.
+  To build the Qhull executables and libqhullstatic
+  - Extract Qhull from qhull...tgz or qhull...zip
+  - cd src/libqhull_r  # cd src/libqhull 
+  - make
+
+  
+-----------------
+Installing Qhull with CMake 2.6 or later
+
+  See CMakeLists.txt for examples and further build instructions
+  
+  To build Qhull, static libraries, shared library, and C++ interface
+  - Download and extract Qhull (either GitHub, .tgz file, or .zip file)
+  - cd build
+  - cmake --help  # List build generators
+  - make -G "<generator>" .. && cmake ..  
+  - cmake ..
+  - make
+  - make install
+
+  The ".." is important.  It refers to the parent directory (i.e., qhull/)
+
+  On Windows, CMake installs to C:/Program Files/qhull.  64-bit generators
+  have a "Win64" tag.
+  
+  If creating a qhull package, please include a pkg-config file based on build/qhull*.pc.in
+
+  If cmake fails with "No CMAKE_C_COMPILER could be found"
+  - cmake was not able to find the build environment specified by -G "..."
+  
+-----------------
+Installing Qhull with Qt
+
+  To build Qhull, including its C++ test (qhulltest)
+  - Download and extract Qhull (either GitHub, .tgz file, or .zip file)
+  - Load src/qhull-all.pro into QtCreator
+  - Build
+
+-------------------
+Working with Qhull's C++ interface
+
+  See html/qh-code.htm#cpp for calling Qhull from C++ programs
+  
+  See html/qh-code.htm#reentrant for converting from Qhull-2012
+
+  Examples of using the C++ interface
+    user_eg3_r.cpp
+    qhulltest/*_test.cpp
+
+  Qhull's C++ interface is likely to change.  Stay current with GitHub.
+
+  To clone Qhull's next branch from http://github.com/qhull/qhull
+    git init
+    git clone git@github.com:qhull/qhull.git
+    cd qhull
+    git checkout next
+    ...
+    git pull origin next
+    
+  Compile qhullcpp and libqhullstatic_r with the same compiler.  Both libraries
+  use the C routines setjmp() and longjmp() for error handling.  They must 
+  be compiled with the same compiler.
+  
+-------------------
+Calling Qhull from C programs
+
+  See html/qh-code.htm#library for calling Qhull from C programs
+
+  See html/qh-code.htm#reentrant for converting from Qhull-2012
+
+  Warning: You will need to understand Qhull's data structures and read the 
+  code.  Most users will find it easier to call Qhull as an external command.
+
+  The new, reentrant 'C' code (src/libqhull_r), passes a pointer to qhT 
+  to most Qhull routines.  This allows multiple instances of Qhull to run 
+  at the same time.  It simplifies the C++ interface.
+
+  The non-reentrant 'C' code (src/libqhull) looks unusual.  It refers to 
+  Qhull's global data structure, qhT, through a 'qh' macro (e.g., 'qh ferr'). 
+  This allows the same code to use static memory or heap memory. 
+  If qh_QHpointer is defined, qh_qh is a pointer to an allocated qhT; 
+  otherwise qh_qh is a global static data structure of type qhT.
+
+------------------
+Compiling Qhull with Microsoft Visual C++
+
+  To compile 32-bit Qhull with Microsoft Visual C++ 2010 and later
+  - Download and extract Qhull (either GitHub, .tgz file, or .zip file)
+  - Load solution build/qhull-32.sln 
+  - Build target 'Win32'
+  - Project qhulltest requires Qt for DevStudio (http://www.qt.io)
+    Set the QTDIR environment variable to your Qt directory (e.g., c:/qt/5.2.0/5.2.0/msvc2012)
+    If QTDIR is incorrect, precompile will fail with 'Can not locate the file specified'
+
+  To compile 64-bit Qhull with Microsoft Visual C++ 2010 and later
+  - 64-bit Qhull has larger data structures due to 64-bit pointers
+  - Download and extract Qhull (either GitHub, .tgz file, or .zip file)
+  - Load solution build/qhull-64.sln 
+  - Build target 'Win32'
+  - Project qhulltest requires Qt for DevStudio (http://www.qt.io)
+    Set the QTDIR environment variable to your Qt directory (e.g., c:/qt/5.2.0/5.2.0/msvc2012_64)
+    If QTDIR is incorrect, precompile will fail with 'Can not locate the file specified'
+  
+  To compile Qhull with Microsoft Visual C++ 2005 (vcproj files)
+  - Download and extract Qhull (either GitHub, .tgz file, or .zip file)
+  - Load solution build/qhull.sln 
+  - Build target 'win32' (not 'x64')
+  - Project qhulltest requires Qt for DevStudio (http://www.qt.io)
+    Set the QTDIR environment variable to your Qt directory (e.g., c:/qt/4.7.4)
+    If QTDIR is incorrect, precompile will fail with 'Can not locate the file specified'
+

+    or install MSYS (http://www.mingw.org/wiki/msys)
+  - Install MINGW-w64 (http://sourceforge.net/projects/mingw-w64).  
+    Mingw is included with Qt SDK.  
+  - make
+  
+-----------------
+Compiling Qhull with cygwin on Windows
+
+  To compile Qhull with cygwin
+  - Download and extract Qhull (either GitHub, .tgz file, or .zip file)
+  - Install cygwin (http://www.cygwin.com)
+  - Include packages for gcc, make, ar, and ln
+  - make
+
+-----------------
+Compiling from Makfile without gcc
+
+  The file, qhull-src.tgz, contains documentation and source files for
+  qhull and rbox.  
+  
+  To unpack the tgz file
+  - tar zxf qhull-src.tgz
+  - cd qhull
+  - Use qhull/Makefile
+   Simpler Makefiles are qhull/src/libqhull/Makefile and qhull/src/libqhull_r/Makefile
+  
+  Compiling qhull and rbox with Makefile
+  - in Makefile, check the CC, CCOPTS1, PRINTMAN, and PRINTC defines
+      - the defaults are gcc and enscript
+      - CCOPTS1 should include the ANSI flag.  It defines __STDC__
+  - in user.h, check the definitions of qh_SECticks and qh_CPUclock.
+      - use '#define qh_CLOCKtype 2' for timing runs longer than 1 hour
+  - type: make 
+      - this builds: qhull qconvex qdelaunay qhalf qvoronoi rbox libqhull.a libqhull_r.a
+  - type: make doc
+      - this prints the man page
+      - See also qhull/html/index.htm
+  - if your compiler reports many errors, it is probably not a ANSI C compiler
+      - you will need to set the -ansi switch or find another compiler
+  - if your compiler warns about missing prototypes for fprintf() etc.
+      - this is ok, your compiler should have these in stdio.h
+  - if your compiler warns about missing prototypes for memset() etc.
+      - include memory.h in qhull_a.h
+  - if your compiler reports "global.c: storage size of 'qh_qh' isn't known"
+      - delete the initializer "={0}" in global.c, stat.c and mem.c
+  - if your compiler warns about "stat.c: improper initializer"
+      - this is ok, the initializer is not used
+  - if you have trouble building libqhull.a with 'ar'
+      - try 'make -f Makefile.txt qhullx' 
+  - if the code compiles, the qhull test case will automatically execute
+  - if an error occurs, there's an incompatibility between machines
+      - If you can, try a different compiler 
+      - You can turn off the Qhull memory manager with qh_NOmem in mem.h
+      - You can turn off compiler optimization (-O2 in Makefile)
+      - If you find the source of the problem, please let us know
+  - to install the programs and their man pages:
+      - define MANDIR and BINDIR
+      - type 'make install'
+
+  - if you have Geomview (www.geomview.org)
+       - try  'rbox 100 | qconvex G >a' and load 'a' into Geomview
+       - run 'q_eg' for Geomview examples of Qhull output (see qh-eg.htm)
+
+------------------
+Compiling on other machines and compilers
+
+  Qhull may compile with Borland C++ 5.0 bcc32.  A Makefile is included.
+  Execute 'cd src/libqhull; make -f Mborland'.  If you use the Borland IDE, set
+  the ANSI option in Options:Project:Compiler:Source:Language-compliance.
+  
+  Qhull may compile with Borland C++ 4.02 for Win32 and DOS Power Pack.  
+  Use 'cd src/libqhull; make -f Mborland -D_DPMI'.  Qhull 1.0 compiles with 
+  Borland C++ 4.02.  For rbox 1.0, use "bcc32 -WX -w- -O2-e -erbox -lc rbox.c".  
+  Use the same options for Qhull 1.0. [D. Zwick]
+  
+  If you have troubles with the memory manager, you can turn it off by
+  defining qh_NOmem in mem.h.
