The Visualization and Computer Graphics Library (VCG for short) is a open source portable C++ templated library for manipulation, processing and displaying with OpenGL of triangle and tetrahedral meshes.
VCG Lib uses a git repository hosted by github at http://github.com/cnr-isti-vclab/vcglib/
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 of the Italian National Research Council Institute ISTI ( http://vcg.isti.cnr.it ), like metro and MeshLab.
