VCGlib is a templated, header-only C++ library with no external dependencies for manipulating, processing, cleaning, and simplifying triangle and tetrahedral meshes. It is the core engine behind tools like MeshLab and Metro, offering state-of-the-art mesh processing algorithms.

Use cases

• simplify large triangle meshes with quadric-error edge collapse
• repair broken or non-watertight 3D meshes
• compute Hausdorff distance between two meshes
• compute geodesic paths and curvature on meshes
• sample Poisson-disk point distributions over a mesh surface
• extract isosurfaces and generate meshes with advancing front
• smooth and fair mesh geometry
• optimize texture coordinates on a mesh

When to choose

• you need a dependency-free, header-only C++ library for triangle mesh processing
• you are building 3D scanning, reconstruction, or mesh cleanup pipelines
• you want proven algorithms used by MeshLab in your own C++ project
• you need mesh simplification, repairing, or sampling in a native application

When to avoid

• you need a permissive license - VCGlib is GPL-3.0
• you want a ready-to-use GUI application rather than a C++ library (use MeshLab instead)
• you work primarily with point clouds or volumetric data rather than triangle meshes
• you need bindings for Python or other non-C++ languages
