    qhull 3.0 2001/02/11 -- Contents of qhull3.0.tar.gz · dff2d0e6
    unknown authored
    Changes to distribution
     - added qconvex, qdelaunay, qhalf, and qvoronoi
     - added qhull-interface.cpp on calling Qhull from C++ [K. Erleben]
     - renamed to qhull3.0/.
     - added eg/, html/, and src/ directories
    
    Changes to URLs
     - MathLab6 qhull: convhulln, delaunayn, griddatan, tsearchn, vororoin [Z. You]
     - Wolfram Research wrote a Mathematica interface for qdelaunay [Hinton]
     - Geomview moved from www.geom.umn.edu to www.geomview.org [M. Phillips}
     - added URLs for tcsh and cygwin to README.txt
    
    Changes to documentation
     - reorganized table of contents and renamed qh-man.htm to index.htm
     - wrote program documentation, dropped qh-opt.htm and qh-optv.htm
     - added quick reference, qh-quick.htm
     - reorganized qh-rbox.htm and renamed it to rbox.htm
     - split up qh-c.htm for quick navigation
    
    Corrections to code
     - fixed type of arg for error message in qh_initqhull_globals [N. Max]
     - fixed incorrect initialization of qh MINdenom_1 for scalepoints
     - fixed drop dim for 'H Qbk:0Bk:0'.  Added qh.feasible_point to qh_projectinput
     - qh_WARNnarrow is angle between facet normals.  Negate for warning message.
     -   statistics for Wangle/etc. concerns facet normals.  Reworded [E. Voth]
     - fixed error message for 'FC v'
     - report cospherical points if Delaunay and error in qh_scalelast()
    
    Changes to code
     - turn on Pg if (QVn or QGn) and not (Qg or PG)
     - turn on Qc if format option 'Fc', 'FP', or 'Gp' (removes warning)
     - removed last good facet unless ONLYgood ('Qg').
     - added count of non-simplicial or merged facets to 'FS'
     - added count of non-simplicial facets to 's' (OK if #vertices==dim)
     - added Znonsimplicial and Znowsimplicial to 'Ts'
     - allow Mathematica output of dual polytope for halfspace intersection
     - added qh_checkflags to globals.c for multiple front ends
     - qh_initqhull_globals sets qh.MERGING if qh.MERGEexact
     - removed hashentryT.  It is no longer used.
    
    Changes to prompts and warnings
     - reorganized prompts
     - reorganized synopsis for rbox.c
     - print warning if 'Fc' or 'FP' with 'd QJ'.  Coincident points are unlikely.
     - ignore warning if options 'v i Pp'.  qvoronoi users may need Delaunay tri.
     - reworded warning if 'Pg' and 'QVn' is not a vertex.
     - reworded warning for 'Qx Tv', qh_check_points() in poly2.c
     - if 'Pp', turn off warning for 'Qbb' without 'd' or 'v'
     - in qh_printsummary() of Voronoi and Delaunay, distinguish QVn, QGn, Pdn, PDn
    
    Changes to FAQ
     - added FAQ item for nearly flat Delaunay triangles [Z. You]
     - added FAQ item for area and volume [R. Konatham]
     - added FAQ item for Voronoi diagram of a square [J. Yong]
     - edited FAQ item on point location in Delaunay triangles [Z. You]
     - added FAQ item on nearly flat Delaunay triangles [Dehghani]
     - added FAQ item about halfspace intersection [V. Tyberghein]
     - added FAQ item for missing ridges [M. Schmidt]
     - added FAQ item about qh_call_qhull [R. Snyder]
     - added FAQ item about memory statistics [Masi]
     - added FAQ item on meshing non-convex objects
     - added FAQ item on MATLAB and Mathematica interface
