GTS is open source software that deals with 3D surfaces meshed with interconnected triangles. It is written in C and provides a simple and efficient library to scientists dealing with computational surface meshes. Its main features include set operations on surfaces, surface refinement and coarsening, dynamic view-independent continuous level-of-detail, and triangle strips generation for fast rendering. GTS also offers packages, Python bindings, developmental features, and documentation. The latest release in 2006 had bug fixes and minor changes.
