CGAL (Computational Geometry Algorithms Library) is a mature C++ library providing efficient and reliable algorithms for computational geometry, including triangulations, convex hulls, boolean operations, mesh processing, and arrangements. Since version 5.0 it is header-only, distributed as source tarballs released twice a year.

Use cases

• compute convex hulls and triangulations of point sets
• perform boolean operations on polygons
• reconstruct surfaces from point clouds
• process and remesh 3D meshes
• compute Voronoi diagrams and arrangements
• implement geometric algorithms with exact arithmetic

When to choose

• you need robust, exact-arithmetic computational geometry in C++
• you work with meshes, point clouds, or polygon processing
• you want a well-tested, long-established geometry library

When to avoid

• you need a lightweight runtime dependency rather than a large template-heavy header library
• your project is not C++
• you need GPU-accelerated geometry processing
