matGeom

matGeom is designed to be a Matlab library for geometric computing. Using the functions included in matGeom, you are able to create, transform, manipulate and display geometric primitives (points, lines, polygons, planes, etc.).

Typical operations involve creation of shapes, computation of intersections, transforming shape coordinates, combining shapes to create new ones. You can have a look at the demo pages to have an overview of the syntax and possibilities.

The library is organised into several packages: · geom2d for general functions in the 2D euclidean plane, · polygons2d for working with polylines and polygons, · graphs for working on planar graphs, · polynomialCurves2d that can be used for fitting geometric curves on set of points, typically after a coutour detection procedure, · geom3d for general functions in the 3D euclidean space, · meshes3d for manipulating meshes composed of several polygonal faces.

The library also contains functions for manipulation of surface meshes.
