Upgrade your meshes!
Mmg is an open source software for simplicial remeshing. It provides 3 applications and 4 libraries:
  • the mmg2d application and the libmmg2d library: adaptation and optimization of a two-dimensional triangulation and generation of a triangulation from a set of points or from given boundary edges
  • the mmgs application and the libmmgs library: adaptation and optimization of a surface triangulation and isovalue discretization
  • the mmg3d application and the libmmg3d library: adaptation and optimization of a tetrahedral mesh and implicit domain meshing
  • the libmmg library gathering the libmmg2d, libmmgs and libmmg3d libraries

Because we believe that working together is the better way to improve, our applications are and will remain open-source (LGPL).
Discover the Mmg Platform (please, be patient, it may take a while).
