PolyMLib is an object-oriented software toolkit that provides a set of objects and corresponding methods to repair, optimize, review and edit triangle mesh models.  It can be used to analyze surface properties, such as smoothness and curvature distribution, as well as to repair and optimize surface meshes. Hence, it is well suited to post-process meshes emerging from a 3D scanning process.  These meshes often contain topological inconsistencies and geometric artifacts like measurement noise, and also the mesh complexity usually needs to be reduced.


A fully functioning graphical demonstration program is provided to illustrate how to use the functionality. Full documentation, examples and training can be provided to allow quick and easy understanding of the functions available.
