libigl is a simple C++ geometry processing library offering a wide range of algorithms for triangle and tetrahedral meshes, including deformation, parameterization, and mesh repair. It is header-only, works with Eigen, and also provides Python bindings.

Use cases

• process and deform 3D triangle meshes in C++
• compute geodesic distances on meshes
• parameterize meshes for texture mapping
• remesh and repair 3D models
• implement geometry research prototypes quickly
• use geometry algorithms from Python

When to choose

• you need a broad, well-tested set of mesh processing algorithms in C++
• you want a header-only library that integrates easily with Eigen
• you are prototyping geometry processing research

When to avoid

• you need GPU-accelerated geometry processing
• you want a full 3D modeling application rather than a library
• your project cannot accept the library's license terms
