JIGSAW

JIGSAW is a two- and three-dimensional mesh generator; designed to generate high-quality triangulations and polyhedral decompositions of general planar, surface and volumetric domains. JIGSAW includes refinement-based algorithms for the construction of new meshes, optimisation-driven techniques for the improvement of existing grids, as well as routines to assemble (restricted) Delaunay tessellations, Voronoi complexes and Power diagrams.

JIGSAW is written in c++; defining a basic command-line interface and a c-format API. JIGSAW's command-line utilities are driven using two ascii-based file formats: *.jig files, used to store user-defined configuration settings, and *.msh files, used to store mesh-specific and geometric data.

• *.jig file format.
• *.msh file format.
