history
Project history and usage
GTS, the GNU Triangulated Surface Library, is a C library for working with three-dimensional surfaces represented as interconnected triangles. Its package-manager significance comes from a practical mix of computational geometry algorithms, mesh file converters, and Unix-style command-line tools such as `stl2gts`, `gts2stl`, `delaunay`, `gtscheck`, and `happrox`.
Project history
The GTS web site describes the project as free software under the LGPL and as a C library using an object-oriented design inspired by GTK+. Its initial goal was to give scientists a simple and efficient library for 3D computational surface meshes.
Early public news on the project site in 2000 announced a web site update, examples, and version 0.3.0. The 0.4.0 release in January 2001 reorganized the object hierarchy around points, vertices, segments, edges, triangles, faces, and surfaces; it also rewrote Delaunay triangulation and improved boolean operations and surface coarsening.
The 0.5.1, 0.6.0, and 0.7.x series expanded GTS from a geometry library into a toolkit with converters, validation tools, boolean operations, isosurface extraction, refinement, coarsening, graph operations, and progressive-surface support. Version-control history moved from CVS to darcs in the 0.7.4 cycle, and the site links the darcs repository as the development source.
Adoption history
GTS was adopted by scientific and graphics projects that needed robust triangulated-surface operations without building a geometry kernel from scratch. The official projects page lists users including MyFon, Mesh Viewer, Gerris Flow Solver, Divipro, Chips, K-3D, and TriAero.
The library also became a durable distribution package: the input metadata records packaging across Homebrew, Debian, Ubuntu, Fedora-family, MacPorts, Nix, Arch, and openSUSE ecosystems. Its command-line converters and `gts-config` helper made it useful both as a library dependency and as a standalone mesh utility package.
How it is used
Typical GTS usage is split between C programs linking against the library and command-line workflows around mesh conversion and checking. The reference manual covers data structures such as heaps, vectors, object classes, point/vertex/edge/face/surface types, kd-trees, bounding-box trees, boolean operations, simplification, refinement, isosurfaces, Delaunay triangulation, differential geometry operators, and graph partitioning.
Package users encounter GTS through executable tools that convert STL, DXF, and OOGL-like formats, generate Delaunay triangulations, check surface consistency, approximate terrain models, and transform meshes. The installation docs describe a traditional autotools build and a dependency on GLib.
Why package nerds care
GTS is exactly the kind of library that package maintainers keep around because it is small, old, useful, and embedded in other scientific software. It bridges desktop-era GLib conventions, robust computational geometry, and Unix filters for mesh data, so even users who never write against its C API may depend on it through CAD, visualization, or simulation packages.
For Homebrew-style package culture, GTS is also notable because it ships many tiny executables from one library formula. That makes it useful for quick mesh conversions and for testing whether old scientific build systems can still find a `gts-config` or pkg-config path.

Related projects
- The official site links GTS to GLib and GTK+ design conventions, Jonathan Shewchuk's robust predicates, pygts Python bindings, Gerris Flow Solver, K-3D, TriAero, and other mesh or simulation tools. Its command-line tools also make it adjacent to STL processing, Delaunay triangulation utilities, CAD/CAM packages, and scientific visualization stacks.
