  • v8.0.1   Qhull 8.0.1 (2020.2 2020/07/24) C++ interface - Removed Java-style iterators for Coordinates and PointCoordinates. std::vector has an expensive copy constructor and copy assignment, and a pointer to std::vector is vulnerable to mysterious overwrites (e.g., deleting a returned value and reusing its memory). Qt's 'foreach' should not be used for Coordinates and PointCoordinates. It copies std::vector - QHULL_DECLARE_SEQUENTIAL_ITERATOR: allow temporary results The Jave-style iterator copies the container. Same as Qt's Q_DECLARE_SEQUENTIAL_ITERATOR - QhullHyperplaneIterator,QhullPointIterator,QhullPointsIterator: allow temporary results These Java-style iterators copy the container instead of pointing to the container - QhullLinkedListIterator,QhullFacetListIterator,QhullVertexListIterator: allow temporary results These Java-style iterators copy the container instead of pointing to the container - QhullSetIterator,QhullFacetSetIterator,QhullPointSetIterator,QhullVertexSetIterator: add documentation about temporary results These Java-style iterators have always copied the container - QhullUser.h, user_eg3_r.cpp: Removed C++11 dependencies [G. Romualdi, S. Grein #65, #66,#67] QhullUser.cpp: Use intptr_t to avoid C++11 dependencies [S. Grein, Spacelm #68] - QhullVertex.cpp: moved the copy constructor to the code file. It was inline. Testing and example programs - user_eg3_r.cpp: Renamed 'inputSites' to 'voronoiRegions' in qvoronoi_o/qvoronoi_pfn [M. Konecny #72] - user_eg3_r.cpp: Replaced C++11's range-based for loops with Qhull's Java-style iterators - qh-code.html: Updated qhullcpp code example [M. Konecny #71] - QhullFacet_test.cpp: fixed hyperplane epsilon test in t_getSet. The epsilon due to rotation is unknown. - Qhull*List_test.cpp,Qhull*Set_test.cpp,QhullRidge_test,QhullVertex_test: test Qt's 'foreach' in t_foreach - Qhull*List_test.cpp,Qhull*Set_test.cpp,QhullRidge_test,QhullVertex_test: test C++11 range for in t_foreach - Qhull*List_test.cpp,Qhull*Set_test.cpp: test Java-style iterator in t_java_iterator - Coordinates_test.cpp,PointCoordinates_test.cpp,QhullHyperplane_test.cpp,QhullPoint_test.cpp,QhullPoints_test.cpp,RboxPoints_test.cpp test C++11 range for, Qt's 'foreach', and Java-style iterators (if available) Builds - README.txt: Fixed "cmake -G" for "Installing Qhull with CMake" - README.txt: Added a note on 'make install' to "Installing Qhull on Unix" - README.txt: Added 'make test' to "Installing Qhull on Unix" - README.txt: Added 'ctest' to "Installing Qhull with CMake" - README.txt: Added pkg-config notes to "Installing Qhull with CMake" - README.txt: Added usage notes for Windows to "Installing Qhull with CMake" - README.txt: Added instructions for downloading MinGW-W64-install.exe - build/qhull_p.pc.in,qhull_r.pc.in: Delete obsolete files [T.

Roehling #63] Documentation - qh-code.htm, qhull-news.html: Add Toronto and McCarthy, "Practically accurate floating-point math".

  • v7.3.2   Qhull 2019.1 2019/06/21 (7.3.2) released Qhull 2019.1 contains bug fixes and improvements to logging, error reporting, and merging. - Fixed fifty bugs, including initialization bugs and memory corruption bugs in qh_readpoints and qh_option. See Bugs and Changes.txt. - New option 'TAn' stops Qhull after adding n points. - New option 'Tf' flushes qh_fprintf. Use 'Tf' when debugging segfaults. - New options '--help', '-?', and '--' display a short help message. Under Git for Windows or MSYS2, 'qhull' waits for stdin. - Option 'TP-1' turns on tracing after qh_buildhull and qh_postmerge complete. It traces qh_check_maxout, qh_prepare_output, qh_triangulate, and qh_voronoi_center - Options 'TI' and 'TO' do not require a space before the filename. - An unknown Qhull option is an error. It was a warning. Override with option 'Qw'. - Short or long input to Qhull is an error. It was a warning. Override with option 'Qa'. - Documentation encourages the use of joggled input. Joggled input is less precise than facet merging, but it cannot incur merge errors for degenerate input. - Documentation refers to 'dupridge' instead of 'duplicate ridge'. A dupridge is an erroneous ridge between four or more facets. - Fixed documentation for qh_findbestfacet. Delaunay triangulations may return an adjacent triangle [F. Drielsma]. - CMake: export QhullTargets for config.cmake.in and find_package [tamasmeszaros] - The C++ interface includes new methods, hasNext() and hasPrevious(), for QhullFacet and QhullVertex. - Test scripts qtest.sh and q_benchmark help with logging and optimizing Qhull, particularly for intermittent errors and bad cases for Qhull. Fixed bugs in Qhull 2015.2 (see Changes.txt for the full list) - qh_buildcone_onlygood ('Qg') corrupted memory if it called qh_delfacet. - qh_check_maxout did not include qh.DISTround when checking f.maxoutside - qh_distround did not acount for 'Rn' (random roundoff) in option 'QJn' - qh_findbestfacet should document that it may return an adjacent triangle for Delaunay triangulations [F. Drielsma] - qh_findfacet_all should not search visible facets or f.upperdelaunay facets [P. Virtanen, S. Dominguez, J.Arkin] - qh_findgood may report a bad facet for qh.GOODvertex ('QVn'). Restrict the search to good facets. - qh_freebuild deleted unattached ridges, leading to a double delete - qh_initial_hull tested 'maybe flipped' instead of 'clearly flipped'. As a result facets could be incorrectly oriented, leading immediately to 'Only 4 facets remain' [S. Caron, P. Virtanen, D. Sterratt, others] - qh_initstatistics was missing initialization. As a result, the final qh_checkoutput may be skipped. - qh_initstatistics cannot use qh_fprintf to report errors. Use qh_fprintf_stderr - qh_maxsimplex did not detect nearly flat simplices except for the last vertex. It assumed the max coordinate was approximately 1. As a result, Qhull reported false narrow hulls or false low dimensional inputs. [J.R. Roussel, D. Sterratt] - qh_option could overflow the qh.qhull_options buffer - qh_partitionpoint could leave an outside point before qh.next_facet, leading to a skipped point. - qh_stddev was incorrect. It should be sqrt of absolute value. - 'Qbb' scaled the last coordinate to qh.MAXwidth causing loss of precision. It should be qh.MAXabs_coord. - 'rbox' and 'user_eg3' returned non-zero exit status for their help prompt. Should be 0. - 'rbox Cn,r,m' does not produce points for 'rbox r' - An error in qh_initqhull_start2 could loop forever. Need to set qh.NOerrexit - Do not call qh_check_points ('Tv') if reporting an error and qh.FORCEoutput ('Po') - If 'd' or 'v' was used with 'H', memory corruption occurred. Should be disallowed. - Improved searching of coplanar facets by qh_findbesthorizon. - Options 'Pdk' and 'Pdk' always returned the closest facet. This should only occur with option 'Pg'. - PointCoordinates::appendPoints should not require whitespace after a point - Setting qh.MINoutside could lead to verification ('Tv') failures. Fixed by setting qh.KEEPnearinside and calling qh_partitionpoint in qh_partitionall
