- Qhull Home Page

  Qhull computes convex hulls, Delaunay triangulations, halfspace intersections about a point, Voronoi diagrams, furthest-site Delaunay triangulations, and furthest-site Voronoi diagrams. It runs in 2-d, 3-d, 4-d, and higher dimensions. It implements the Quickhull algorithm for computing the convex hull. Qhull handles roundoff errors from floating point arithmetic. It can approximate a convex hull.

- Download: Qhull version 1.0 (92K)

  Type: C source code for 32-bit architectures

  Version 1.0 is a fifth the size of version 2.4. It computes convex hulls and Delaunay triangulations. If a precision error occurs, it stops with an error message. It reports an initialization error for inputs made with 0/1 coordinates.

  Version 1.0 compiles on a PC with Borland C++ 4.02 for Win32 and DOS Power Pack. The options for rbox are "bcc32 -WX -w- -O2-e -erbox -lc rbox.c". The options for qhull are the same. [D. Zwick]

- Download: Qhull version 1.0 (Mac) (180K)

  Type: C source code, packaged for Macintosh w/68881

  The Macintosh implementation of Qhull 1.0 reads input from a file and returns the results to a file. The code is compiled for a 68881 floating point coprocessor. The package includes Think C projects for Qhull and the rbox input generator.
