It can be used to automate the process of decoding 3D mesh inherent properties and ease data classification and retrieval. For each analyzed dataset the following information are extracted: * Number of Vertices (Unreferenced vertices are listed separately) * Number of Faces * Number of Edges * Number of Connected Components * Number of Boundaries * Number of Isolated Vertices (i.e. Unreferenced) * Manifold * Genus (Computed only for Manifold Datasets) * Self-Intersection (Currently computed only for Datasets with less than 3M faces) * Orientability * Orientation * Regularity (We consider as regular those meshes generated through regular subdivision. Each non boundary vertex of a regular mesh has 6 incident edges, if there are only 5 incident edges the mesh is said to be semi-regular, irregular in all other cases) The application has no graphical interface but works as the "Metro" tool on command line. TriMeshInfo is written in C++ and makes use of the VCL library. The tool supports two file formats ply (as described in the following document http://vcg.sourceforge.net/img/wiki_up/plyformat.pdf) and off (as described in http://www.geomview.org/docs/html/geomview_41.html#SEC44) .
