history
Project history and usage
Qhull is a command-line and library toolkit for computing convex hulls, Delaunay triangulations, Voronoi diagrams, and halfspace intersections in general dimensions.
Project history
C. B. Barber developed Qhull as a general-dimensional implementation of the Quickhull algorithm, with the official documentation carrying a copyright period beginning in 1995.
The project grew beyond convex hulls to provide Delaunay triangulations, Voronoi diagrams, halfspace intersections, furthest-site variants, random point generation, C libraries, and a C++ interface.
Later releases introduced the reentrant libqhull_r interface and modernized CMake, shared-library, and C++ build support.
Adoption history
Qhull became a long-lived packaged component because it supplies both Unix command-line programs and reusable C and C++ libraries for common computational-geometry operations. source_facts.package-manager records adoption across Alpine, Homebrew, Debian/Ubuntu, Fedora-family systems, MacPorts, Nix, Arch Linux, and openSUSE.
The project later introduced a reentrant library and C++ interface, improving its suitability as an embedded geometry backend and for concurrent applications.
How it is used
Users pipe point sets into qconvex, qdelaunay, qvoronoi, qhalf, or qhull and select output, precision, and verification options. Applications can instead link the reentrant C library or C++ interface; rbox generates test point distributions.
Why package nerds care
Qhull turns a difficult family of numerical geometry problems into composable Unix filters and linkable libraries. Its explicit treatment of floating-point imprecision, merged facets, joggled input, verification, and diagnostic output makes it especially valuable in scientific and engineering stacks.
Timeline
- 1995: Qhull's documented copyright period begins.
- 2015: The reentrant libqhull_r interface became the recommended library interface.
- 2020: The 2020.2 release updated build systems and the C++ interface.
Related projects
- The official manual recommends Fukuda's cdd for high-dimensional inputs with a small number of non-simplicial facets and discusses specialized triangulation tools for constrained or low-dimensional problems.
