 The library, composed by more than 100k lines of code, is released under the GPL license, and it is the base of most of the software tools of the [Visual Computing Lab](http://vcg.isti.cnr.it) of the Italian National Research Council Institute ISTI , like MeshLab, metro and many others.
 
 The VCG library is tailored to mostly manage triangular meshes: The library is fairly large and offers many state of the art functionalities for processing meshes, like:
