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 is copyrighted software. Please read COPYING.txt and REGISTER.txt
before using or distributing Qhull.

algorithm for convex hulls," ACM Trans. on Mathematical Software,

To modify Qhull, particularly the C++ interface
Qhull is on GitHub
(http://github.com/qhull/qhull/wiki, 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.
Or 'qconvex --help' or 'qconvex -?'
- 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 regularly use qhull on a Windows host, install a bash shell such as
https://gitforwindows.org/ # based on MSYS2
https://github.com/git-for-windows/git/wiki
http://www.msys2.org/
https://github.com/msys2/msys2/wiki
[mar'19] Git for Windows v2.21 requires 'qhull --help'
www.cygwin.com
www.mingw.org/wiki/msys # for Windows XP
Road Bash (www.qhull.org/bash) # based on MSYS
-----------------
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. Qhull's data structures are substantial larger as
64-bit code than as 32-bit code. This may slow down Qhull.
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
- qhulltest depends on shared libraries QtCore.a and QtTest.a. They may need to be copied
into the bin directory. On Windows, copy Qt5Core.dll and Qt5Test.dll, e.g., qt/5.11.2/msvc2017_64/bin
- If qhulltest fails without an error message, check for missing Q54Core.dll and Qt5Test.dll
-------------------
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/wiki
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.
