New Features: - Add Maple output ('FM') for 2-d and 3-d convex hulls [T. Abraham] Breaking Code Changes: - Annotate C code with 'const'. An ANSI compatible compiler is required. Bug Fixes and Code Changes: - Fixed qh_findbest() for upperdelaunay facets w/o better, lower neighbors For library users and some qhull users [A. Cutti, E. Milloti, K. Sun] - Preserved qhmem.ferr in qh_memfreeshort() for library users - Removed 'static' from qh_compare... for io.h and merge.h [V. Brumberg] - Split out qh_initqhull_start2() to avoid allocating qh_qh - Split out qh_freeqhull2() to avoid freeing qh_qh - Split out qh_produce_output2() and qh_prepare_output() - qh_initstatistics() frees a previously existing qh_qhstat - qh_initqhull_start2() checks that qh_initstatistics() called first Documentation: - Add warning to findDelaunay() and qh_in.htm about tricoplanar facets - Noted Edelsbrunner's Geometry & Topology for Mesh Generation [qh-impre.htm] - Noted Gartner's Miniball algorithm [qh_impre.htm] - Noted Veron and Leon's shape preserving simplification [qh_impre.htm] qhull 2003.1 2003/12/19 Bug Fixes: - Reversed coordinate order for qh.ATinfinity in qh_projectinput [V. Brumberg] This effects: Qhull library 'd' or 'v' users with 'Qz' and unequal coordinate ranges. qdelaunay/qvoronoi users with 'Qbk:0Bk:0', 'Qz', and unequal coordinate ranges Changes to code: - Replaced qh_VERSION with qh_version in global.c [B. Pearlmutter] The previous techniques were either clumsy or caused compiler errors - Removed unused variables from qh_findbest and qh_findbestnew [B. Pearlmutter] - Note that qh.TESTpoints was added in 2002.1 for tsearch implementation Changes to distribution: - Added Unix distribution including Debian files [R. Laboissiere] The previous Unix distribution is now the source distribution - Added rpm distribution [L. Mazet] - Investigated generation of Win32 dll. Need to define a C++ interface. Changes to documentation: - Moved Qhull to www.qhull.org (geom.umn.edu is not available) - The Geometry Center is archived at http://www.geom.uiuc.edu - Reviewed introduction to each program Triangulated output ('Qt') is more accurate than joggled input ('QJ') qdelaunay is 'qhull d Qbb' [C. Ulbrich] qvoronoi is 'qhull v Qbb' Added example of non-simplicial intersection to halfspace intersections - Added warning about using the Qhull library. - Added qhull timings to When to use Qhull [C. Ulbrich] - Reorganized the home page index and the manual index - Moved qh-home.htm to index.htm Changes to examples - Fixed options for eg/eg.t23.voronoi.imprecise [B. Pearlmutter]
