Geogram is a programming library with geometric algorithms. It has

geometry-processing functionalities:

- [surface reconstruction](https://github.com/BrunoLevy/geogram/wiki/Reconstruction)

- [remeshing](https://github.com/BrunoLevy/geogram/wiki/Remeshing)

- [parameterization and texturing](https://github.com/BrunoLevy/geogram/wiki/Texturing)

- [Intersections and Boolean operations](https://github.com/BrunoLevy/geogram/wiki/BooleanOps)

- [Constructive Solid Geometry](https://github.com/BrunoLevy/geogram/wiki/CSG)

It also has lower-level algorithm:

- [Exact numbers / exact predicates](https://github.com/BrunoLevy/geogram/wiki/Exact)

- [Delaunay triangulations in 2D](https://github.com/BrunoLevy/geogram/wiki/Delaunay2D)

  and highly efficient parallel [Delaunay triangulations in 3D](https://github.com/BrunoLevy/geogram/wiki/Delaunay3D)

- Memory efficient surfacic/volumetric/hybrid [mesh data structure](https://github.com/BrunoLevy/geogram/wiki/Mesh)

- Efficient [geometric search data structures](https://github.com/BrunoLevy/geogram/wiki/Raytrace) for

  intersection and raytracing (AABBs, KdTrees, ...)

- [Spectral mesh processing](https://github.com/BrunoLevy/geogram/wiki/ManifoldHarmonics)

- [Linear solver on CPU and GPU](https://github.com/BrunoLevy/geogram/wiki/OpenNL)

Geogram received the [Symposium on Geometry Processing Software Award](http://awards.geometryprocessing.org/)

in 2023.

Geogram contains the main results in Geometry Processing from the former

ALICE Inria project, that is, more than 30 research articles published

in ACM SIGGRAPH, ACM Transactions on Graphics, Symposium on Geometry 

Processing and Eurographics. It was supported by two grants from the

European Research Council (ERC): GOODSHAPE and VORPALINE.
