Geogram is a C++ programming library of geometric algorithms for geometry processing, including surface reconstruction, remeshing, Boolean operations, and Delaunay triangulations in 2D and 3D. It also provides lower-level building blocks such as exact predicates, mesh data structures, spatial search structures, and CPU/GPU linear solvers.

Use cases

• generate 3D meshes from point clouds
• remesh a triangle mesh to improve quality
• compute Boolean operations on 3D solids
• build a Delaunay triangulation in 3D
• perform constructive solid geometry on meshes
• raytrace against a triangle mesh
• parameterize and texture a 3D surface
• solve sparse linear systems on CPU or GPU

When to choose

• you need robust, well-tested computational geometry algorithms in C++
• you need mesh generation, remeshing, or surface reconstruction
• you need exact arithmetic predicates for geometric robustness
• you want a geometry-processing library with a SGP Software Award pedigree

When to avoid

• you need a high-level 3D viewer or GUI out of the box
• your project is not in C++ or lacks a C++ build toolchain
• you only need simple 2D drawing or rendering rather than geometry algorithms
