Geometry Central is a modern C++ library of data structures and algorithms for geometry processing, with a particular focus on surface meshes. It provides a polished halfedge mesh class, geometric quantities from discrete differential geometry, algorithms like surface distance and direction fields, and sparse linear algebra tools built on Eigen.

Use cases

• process and modify 3D surface meshes in C++
• compute geometric quantities like normals and curvature on meshes
• compute geodesic distances on surfaces
• generate direction fields on meshes
• work with intrinsic Delaunay triangulations
• solve sparse linear systems for geometry problems
• build geometry processing research prototypes

When to choose

• you need a modern, header-friendly C++ library focused on surface mesh geometry processing
• you want discrete differential geometry operators and algorithms out of the box
• you want efficient mesh modification with data containers tied to mesh elements
• you want Eigen-based sparse linear algebra with automatic solver upgrades

When to avoid

• you need a broad computational geometry library covering non-surface geometry like CGAL
• you need volumetric or point-cloud-only processing as the primary focus
• you need Python-first tooling (only third-party bindings like Potpourri3d exist)
• you need rendering or a full GUI, which is delegated to tools like Polyscope
