The **_Visualization and Computer Graphics Library_** (VCGlib for short) is a open source, portable, C++, templated, no dependency, library for manipulation, processing, cleaning, 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, 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:
|
|
|
|
- high quality quadric-error edge-collapse based simplfication,
|
|
- efficient spatial query structures (uniform grids, hashed grids, kdtree, ...) ,
|
|
- 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 is based on this library.
|
|
- 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.
