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.

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'.

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
Qhull 2019.0.1 2019/05/24 (7.3.1)
Qhull options

- merge_r.c/qh_test_degen_neighbors: split from qh_degen_redundant_neighbors and qh_mergefacet
- merge_r.c/qh_test_redundant_neighbors: split from qh_degen_redundant_neighbors and qh_mergefacet
- poly_r.c/qh_attachnewfacets: clear f.neighbors and f.ridges for visible facets, will be deleted
- poly_r.c/qh_matchnewfacets: remove call to qh_checkflipped_all for qh.FORCEoutput, checked by qh_setfacetplane
- poly_r.c/qh_update_vertexneighbors: renamed qh_updatevertices. A future version will optimize
qh_update_vertexneighbors_cone: optimization for cone of new facets
- poly2_r.c/qh_checkconvex: immediate skip of f.tricoplanar facets. Tricoplanar facets not tested. Called before qh_triangulate
- poly2_r.c/qh_initbuild: move 'create sentinels' before qh_createsimplex so that qh.vertex_tail is v0 like f0
- poly2_r.c/qh_initialvertices: cleaned up code for qh_INITIALmax (8-d)
- poly2_r.c/qh_makenewfacets: clear f.neighbors and f.ridges for visible facets, will be deleted
- poly2_r.c/qh_matchdupridge: optimize dupridge for flipped->!flipped, good merge, not !flipped->flipped
- poly2_r.c/qh_matchdupridge_coplanarhorizon: dropped routine. Results same or slightly worse. Complex addition, rarely used
- poly2_r.c/qh_triangulate: rename facet and vertex lists as triangulated_facet_list,etc.
qh_triangulate does not maintain qh.newfacet_list or qh.visible_list
- poly2_r.c/qh_triangulate: ignore qh.NEWfacets. qh_checkpolygon is not valid inside qh_triangulate
- rboxlib_r.c/qh_rboxpoints2: split function from qh_rboxpoints to avoid -Wclobbered
- stat_r.c/qh_printstatlevel: remove unused NULLfield
Qhull C++ changes
- Use NULL instead of 0 for pointers
- Remove old style casts such as '(size_t)...'
- Define initializers for default constructors even if explicitly assigned
- Update static initializer list for s_empty_facet, s_empty_ridge, s_empty_vertex
- Coordinates.h: default constructor clears coordinate_array
- Coordinates.h: default iterator constructor clears i
- RboxPoints.cpp/qh_fprintf_rbox: add empty default to switch statement
