Detailed Description

This class checks topology of the mesh presented by triangulations of faces.

The following error are reported:

free links. A link is considered free if it has only one neighboring triangle and at least one of its nodes belongs to interior of the face rather than to its boundary.
cross face errors. It is a situation when a point on a common boundary between two faces has different 3d coordinates on each triangulation. The error is reported if the distance is greater than a deflection written in triangulations.
asynchronous edges. It is an edge having polygons on two neighboring triangulations with different number of points in the polygons.
free nodes – nodes not shared by any triangle.
