Geogram documentation

Geogram is a programming library with geometric algorithms. It has geometry-processing functionalities (reconstruction, parameterization, remeshing, ...). It also has lower-level algorithm (Delaunay/Voronoi, geometric search, solving linear systems...). See the list of mini-tutorials below.

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.
