Name qhull, rbox 2020.2 2020/08/31 (8.0.2) Convex hull, Delaunay triangulation, Voronoi diagrams, Halfspace intersection Documentation: html/index.htm <http://www.qhull.org/html> Available from: <http://www.qhull.org> <http://www.qhull.org/download> <http://github.com/qhull/qhull/wiki> (git@github.com:qhull/qhull.git) News and a paper: <http://www.qhull.org/news> <http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.117.405> 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 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/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. (<https://github.com/qhull/qhull/wiki/Qhull-build-systems>) Install and build instructions follow. See the end of this document for a list of distributed files. ------------------ Index Installing Qhull on Windows 10, 8, 7 (32- or 64-bit), Windows XP, and Windows NT Installing Qhull on Unix with gcc Installing Qhull with CMake 2.6 or later Installing Qhull with Qt Working with Qhull's C++ interface Calling Qhull from C programs Compiling Qhull with Microsoft Visual C++ Compiling Qhull with Qt Creator Compiling Qhull with mingw/gcc on Windows Compiling Qhull with cygwin on Windows Compiling from Makfile without gcc Compiling on other machines and compilers Distributed files Authors ------------------ 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' Install in C:\Git\... # Not 'Program Files\...' otherwise './configure && make' fails 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 - make test 'make install' installs Qhull at '/usr/local/'. It installs pkg-config files at '/usr/local/lib/pkgconfig'. Change the install directory with DESTDIR and PREFIX. To build 32-bit Qhull on a 64-bit host (uses 33% less memory in 4-d) - make new M32=-m32 To build 32-bit Qhull without -fpic (may be faster, but shared library may fail) - make new M32=-m32 FPIC= 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 - cmake -G "<generator>" .. # e.g., for MINGW-w64 -- cmake -G "MSYS Makefiles" .. - cmake .. - make - ctest - make install # If MSYS or UNIX, default CMAKE_INSTALL_PREFIX is '/usr/local' # otherwise if WINDOWS, installs to ../bin, ../include, and ../lib - make uninstall # Delete the files in install_manifest.txt The ".." is important. It refers to the parent directory (i.e., qhull/) CMake installs lib/pkgconfig/qhull*.pc for use with pkg-config If CMAKE_INSTALL_PREFIX is C:/Program Files/qhull, you may need to give 'Users' "full control" to qhull's sub-directories: bin, doc, include, lib, and man (folder > Properties > Security > Edit > Users). On Windows, CMake's 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 cmake fails with "No CMAKE_C_COMPILER could be found" - cmake was not able to find the build environment specified by -G "..." If cmake's gcc smoketest fails after a Windows update - Reinstall MINGW-w64 and delete build/CMakeCache.txt. A Windows update can break gcc process creation for cc1. ------------------ Installing Qhull with Qt To build Qhull, including its C++ test program (qhulltest) - Download and extract Qhull (either GitHub, .tgz file, or .zip file) - Load src/qhull-all.pro into QtCreator - Configure the project to use a Shadow build at the same level as 'src', 'bin', and 'lib' If, instead, the shadow build is a subdirectory of 'build', Qt Creator will install Qhull in 'build/bin' and 'build/lib' - Build - Build qhulltest with a C++11 or later compiler - 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 with exit status 127 and no error message, check for missing Q5Core.dll and Qt5Test.dll ------------------ Working with Qhull's C++ interface See html/qh-code.htm#cpp for calling Qhull from C++ programs Class and method documentation is limited 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. They must be compiled with the same compiler. Qhull provides pkg-config support with build/qhull.pc.in and lib/pkgconfig/qhull*.pc With back-ticks, you can compile your C++ program with the Qhull libraries: g++ `pkg-config --cflags --libs qhullcpp qhullstatic_r` -o my_app my_app.cpp or g++ `pkg-config --cflags --libs qhullcpp qhull_r` -o my_app my_app.cpp qhullcpp must be linked before qhull_r, otherwise the linker reports an error -- "QhullUser ... multiple definition of `qh_fprintf'" ------------------ Calling Qhull from C programs See html/qh-code.htm#library for calling Qhull from C programs Qhull provides pkg-config support with build/qhull.pc.in and lib/pkgconfig/qhull*.pc With back-ticks, you can compile your C program with the Qhull library gcc `pkg-config --cflags --libs qhull_r` -o my_app my_app.c 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 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 - Right-click 'Retarget solution' from toolset v110 to your Platform Toolset File > Save All - 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' - Copy Qt shared libraries, QtCore.dll and QtTest.dll, into the bin directory To compile 64-bit Qhull with Microsoft Visual C++ 2010 and later - 64-bit Qhull has larger data structures due to 64-bit pointers. This may slow down Qhull. - Download and extract Qhull (either GitHub, .tgz file, or .zip file) - Load solution build/qhull-64.sln - Right-click 'Retarget solution' from toolset v110 to your Platform Toolset File > Save All - Build target 'x64' - If build as 32-bit fails, use solution build/qhull-32.sln - 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' If error -- MSB8020: The build tools for Visual Studio 2012 (Platform Toolset = 'v110') cannot be found. - 'Project > Retarget solution' for both qhull-32.sln and qhull-64.sln - 'File > Open' your preferred solution (qhull-32.sln or qhull-64.sln) - 'Save All' both projects - DevStudio may need a restart 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' ------------------ Compiling Qhull with Qt Creator Qt (http://www.qt.io) is a C++ framework for Windows, Linux, and Macintosh Qhull uses QTestLib to test qhull's C++ interface (see src/qhulltest/) To compile Qhull with Qt Creator - Download and extract Qhull (either GitHub, .tgz file, or .zip file) - Download the Qt SDK - Start Qt Creator - Load src/qhull-all.pro - Configure the project to use a Shadow build at the same level as 'src', 'bin', and 'lib' If, instead, the shadow build is a subdirectory of 'build', Qt Creator will install Qhull in 'build/bin' and 'build/lib' - Build - Build qhulltest with a C++11 or later compiler - 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 with exit status 127 and no error message, check for missing Q5Core.dll and Qt5Test.dll ------------------ Compiling Qhull with mingw/gcc on Windows To compile Qhull with MINGW - Download and extract Qhull (either GitHub, .tgz file, or .zip file) - Install GitForWindows (https://gitforwindows.org/) or MSYS2 (http://www.msys2.org/) Install in C:\Git\... # Not 'Program Files\...' otherwise './configure && make' will not work - Install MINGW-w64 with gcc (https://mingw-w64.org/) 1) Goto sourceforge -- https://sourceforge.net/projects/mingw-w64/files/ 2) in folder -- mingw-w64 3) download installer -- MinGW-W64-install.exe Run the installer 1) Select i686/posix/dwarf 2) Install in 'C:\mingw-w64' # Not 'Program Files\...' Rename /c/mingw-w64/mingw32/bin/mingw32-make.exe to make.exe Add the 'C:\mingw-w64\mingw32\bin' directory to your $PATH environment variable Execute 'which make' to check that 'make' is mingw-w64's make - Compile Qhull from the home directory make help make Notes - Mingw is included with Qt SDK in qt/Tools/mingw53_32 - If you use Windows XP Install Road Bash (http://www.qhull.org/bash) or MSYS (http://www.mingw.org/wiki/msys) Install MINGW (http://mingw.org/) ------------------ 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. ------------------ Distributed files README.txt // Instructions for installing Qhull
