Matlab library geometric computing in 2D/3D.

MatGeom is a library for geometric computing with Matlab in 2D and 3D. It contains several hundreds of functions for the creation and manipulation of 2D and 3D shapes such as point sets, lines, polygons, ellipses, 3D meshes, and other shapes.

The MatGeom lirbary corresponds to the concatenation of the "geom2d" and "geom3d" libraries that were distributed on the FileExchange. Distribution as a single library greatly facilitates the interoperability of the functions.

The official homepage for the project is http://github.com/mattools/matGeom. A user manual is available.

Starting from February 2022, the html pages of the functions (obtained with m2html) are available here.

The library is organized into several modules:

• geom2d - General functions in Euclidean plane
• polygons2d - Functions operating on polygons and polylines represented as list of vertices
• graphs - Manipulation of geometric graphs
• geom3d - General functions in 3D Euclidean space
• meshes3d - Manipulation of 3D polygonal meshes (trimesh, quadmesh, or more generic meshes)
