@BrunoLevy01@fosstodon.org I know nothing about geometry libraries, but I've wondered for a while how geogram differs from something like Open Cascade?

@tom_verbeure@mastodon.social Hi, yes it is an excellent question ! The difference is mainly that they manipulate *different* representations of the geometry: - OpenCascade manipulates parametric surfaces (polynomials and rational fractions), used in CAD/CAM - Geogram manipulates meshes, used in scanning/printing (e.g.). And also, Geogram has some low-level functions (Delaunay/Voronoi) targeted towards specific uses (e.g., cosmology).
