Qhull 2019.0.1 (7.3.1)
Qhull options
- Disallow unknown options and other option errors, allow option warnings with 'Qw'
- New option 'Qallow-short': allow input with fewer or more points than coordinates
- New option 'Qwarn-allow': allow option warnings
- New option 'TAn': stop after adding n vertices
- New option 'Tf': flush after qh_fprintf for debugging segfaults

Excessive merging leads to additional topological and wide facet errors
- New experimental option 'Q15-check-duplicates': check for duplicate ridges with the same vertices

In 2015.2 by default, Qhull merged by mergetype/angle with lower angles first

It traces qh_check_maxout, qh_prepare_output, qh_triangulate, qh_voronoi_center

Qhull does not support '--' options. Git for Windows v2.21.0 does not support isatty ('winpty qhull' is OK)
- Allow Qhull extra options Q12 and Q14 for qconvex/qdelaunay/qhalf/qvoronoi
- Allow option 'QRn' (random rotate) for qdelaunay/qhalf/qvoronoi

- Ignore missing space after 'TI' or 'TO'. Allow 'TIinputfile' and 'TOoutputfile'
- Prefix option errors and warnings with 'qhull option error:' or 'qhull option warning:'
- Remove hidden option 'normals' from help prompts for qdelaunay, qhalf, qvoronoi
- Reword short prompts to 'Pdrop-d0:0D0', 'QbBound-0:0.5', and 'off_format'
- Updated qh-quick.htm, 'qhull -', and 'qhull .' for 'T...' and 'Q...' options.
Separate help prompts for 'T options' and 'Trace options'
- Use '-' instead of '_' for word delimiter in option names
Qhull builds, scripts, and debugging

- In qh_printafacet(), changed error output to 'qh ferr'
Bug fixes to C code:
- Use gcc 4.4.0 or later. gcc 4.2.1, 4.2.2, and 4.3.2 -O2 segfaults in qset.c . gcc 4.1.1 was OK
See bug report http://gcc.gnu.org/ml/gcc-bugs/2007-09/msg00474.html
- Rewrite qh_setappend to avoid g++ 4.1, 4.2, and 4.3 strict_aliasing error.

- Fixed qh_findfacet_all(), "REALmin" should be "-REALmax" [L.A. Taylor].
Effects library users for convex hulls and halfspace intersections.
- qh_printfacet [io.c] Removed extra space for neighboring facets
- Report error if d points, Delaunay, and not Qz
- Fixed double-free of facet->centrum for triangulated facets
- Fixed mindist initialization if !testcentrum in io.c findbest_test [Ratcliff]
- Fixed parentheses around warning for missing 'Qc' [qh_initqhull_outputflags]
- Fixed rbox buffer overflow of 'command' when appending seedbuf
- Fixed option string for 'rbox t t999'. Although seed was correctly set to 999,
a random seed was appended to the rbox comment (e.g., 'rbox t t999 t32343')
- Fixed upper bound of sanity check for qh_RANDOMmax in qh_initqhull_globals()
Changes to C code
- Reordered #include from specific to general. Move up .h for module.
- Removed qh.old_stat -- never used
- Removed qh_clearcenters from qh_freeqhull. Duplicated by qh_delfacet
- qh_printcenter [io.c] removed unreachable fprintf argument
- qh_getarea() [geom2.c] ignored on multiple calls (qh.hasAreaVolume)
- qh_getarea() [geom2.c] checks facet->isarea. Set by QhullFacet.facetArea()
- qh_triangulate() [poly2.c] ignored on multiple calls (qh.hasTriangulation)
- Add statistics for vertex_visit and visit_id to buildtracing
- Defined scale and offset parameters for qh_randomfactor
Bug fixes and changes to mem.c/mem.h
- Fixed qhmem.totshort (total short memory in use)
- Memory tracing (T5) redone for sort order by object
- Added full tracing for short memory allocations.
- Added qhmem.totfree (total short memory on freelists)
Increases size of qh_memalloc_ and qh_memfree_
- Added qhmem.totdropped (leftover freesize at end of each short buffer)
- Added qhmem.totunused (short size - request size)
- Added qhmem.totbuffer (total short memory buffer w/o links)
- Added memory statistics to qh_NOmem;
- Added qh_memtotal to track allocated memory
- Renamed qh_memfree parameter to 'insize' for consistency with qh_memalloc
- Removed qhmem.curlong. qa_memfreeshort computes curlong from cntlong and cntfree
- In mem.h, changed ptr_intT to long. qh_meminit() checks that it holds a 'void*'
Fixed g++ and devstudio warnings
- Except for bit field conversions, compiles cleanly with
-Wall -Wextra -Wshadow -Wcast-qual -Wwrite-strings -Wno-sign-conversion -Wconversion
- Fixed warnings at VC8, level 4
- Fix data types to remove conversion warnings [kwilliams]
- Use size_t for calls to malloc,etc [kwilliams]
Retained int sizes for qset.h and mem.h. Follows Qt convention
and is easier to work with. int can be 64-bits if 2 billion facets
- Change literal strings to const char* [kwilliams]
- Added type casts to SETfirst and SETsecond [amorilia+alphax]
- getid_() returns an int [kwilliams]
- Add missing const annotations [kwilliams]
- Fixed 64-bit warnings (marked with "WARN64")
- Convert sizeof to (int) for int parameters
- In libqhull.c, added explicit casts from long to float, Avoids warning
- In global.c, cast time() to int for QRandom-seed. Avoids warning
Changes to C code for C++ support
- Add sln, vcproj, and qtpro files for building Qhull -- add to README notes
- Added dim to vertexT for cpp interface. Reduced size of qh.vertex_visit
- qh_produce_output [io.c] may be called multiple times (C++ interface)
- Moved SETsizeaddr_() to qset.h for use by QhullSet.cpp
- Option 'Tz' sets flag qh.USEstdout for QhullPoints.cpp
- Added support for multiple output runs from QhullPoints.outputQhull
- qh_clear_outputflags() resets the output flags
- qh_initqhull_outputflags split from qh_initqhull_globals
- Added qh.run_id, a random identifier for this instance of Qhull (QhullPoints)
- For qh.run_id, initqhull_start initializes qh_RANDOMseed to time instead of 1
- Extracted qh_argv_to_command (random.c) from qh_init_qhull_command and fixed a buffer overflow
- Moved qh_strtod/qh_strtol from global.c to random.c for use in rboxlib.c
- Split out random functions into random.c
- Added message codes to qh_fprintf(). See its definition in user.c
- Replaced exit, malloc, free, fprintf, and fputs with qh_malloc,...[J.W. Ratcliff]
- Added qh_fprintf, qh_malloc, qh_free, ph_printhelp_narrowhull to user.c
- Moved qh_printhelp_degenerate and qh_printhelp_singular from io.c to user.c
- Clear qh.ERREXITcalled at end of qh_errexit().
Documentation:
- Fixed out-of-date CiteSeer references
- Renamed html/qh-in.htm to html/qh-code.htm
- Add reference to 'Qt' to 'i'
- Add reference to 'FS' to 'FA'
- qh-impre.htm discusses precision issues for halfspace intersection
- Add cross references between options 'FA' and 'FS'
- Added link to Wolfram Research's MathWorld site
- Updated Fukuda's links
- Changed copyright to C.B. Barber for C++, documentation, and merge.c
- Updated Qhull citation with page numbers.
- Proposed project: constructing Voronoi diagram
- Proposed project: computing Voronoi volumes
- Replaced tabs with spaces in qhull.txt and rbox.txt
------------
qhull 2009.1 2009/6/11
This is a maintenance release done by Rafael Laboissiere <rafael@debian.org>.
- src/rbox.c (main): Avoid problems of evaluation order when
pre-incrementing arguments of strtod
- src/io.c (qh_produce_output), src/stat.c (qh_initstatistics): Use %lu
instead of %d in the format string for arguments of type size_t
- html/qhull.man, html/rbox.man: Fix several syntax, macros, and hyphen
problems in man pages
- The Autotools files have been generated with modern version of autoconf (2.63),
automake/aclocal (1.10.2), and libtool (2.2.6)
- Some character issues in the man pages are fixed
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
