Geogram is a programming library with geometric algorithms. It has geometry-processing functionalities:

• surface reconstruction
• remeshing
• parameterization and texturing
• Intersections and Boolean operations
• Constructive Solid Geometry

It also has lower-level algorithm:

• Exact numbers / exact predicates
• Delaunay triangulations in 2D and highly efficient parallel Delaunay triangulations in 3D
• Memory efficient surfacic/volumetric/hybrid mesh data structure
• Efficient geometric search data structures for intersection and raytracing (AABBs, KdTrees, ...)
• Spectral mesh processing
• Linear solver on CPU and GPU

Geogram received the Symposium on Geometry Processing Software Award 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.
