--- Synopsis ---
TriMeshInfo is a tool designed to inspect 3D models and retrieve all the
topological related information. 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) .
