The **_Visualization and Computer Graphics Library_** (VCGlib for short) is an open source, portable, and templated library written in C++, with no external dependencies, for manipulation, processing, cleaning, and simplifying triangle meshes.

|
|
|
|
|
|
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](http://www.meshlab.net/), [Metro](http://vcg.isti.cnr.it/vcglib/metro.html) 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 capabilities for processing meshes, such as:
|
|
|
|
- high quality quadric-error edge-collapse based simplfication
|
|
- efficient spatial query structures (uniform grids, hashed grids, kdtree, etc)
|
|
- advanced smoothing and fairing algorithms
|
|
- computation of curvature
|
|
- optimization of texture coordinates
|
|
- Hausdorff distance computation
|
|
- geodesic paths
|
|
- mesh repairing capabilities
|
|
- isosurface extraction and advancing front meshing algorithms
|
|
- Poisson Disk sampling and other tools to sample point distributions over meshes
|
|
- subdivision surfaces
|
|
|
|
## Notable Applications
|
|
|
|
A number of applications have been developed using the VCGlib:
|
|
|
|
- MeshLab: the renowed open source mesh processing software
|
|
- Metro, the tool for measuring differences between meshes
|
|
- The first high quality out-of-core mesh simplifier that was used by the Stanford Digital Michelangelo project to process their huge 3D scanned models.
