Mmg is a collection of applications and libraries for bidimensional and tridimensional surface and volume remeshing. It consists of:

• the mmg2d application and library: mesh generation from a set of edges, adaptation and optimization of a bidimensional triangulation and isovalue discretization;

• the mmgs application and library: adaptation and optimization of a surface triangulation and isovalue discretization;

• the mmg3d application and library: adaptation and optimization of a tetrahedral mesh, isovalue discretization and Lagrangian movement;

• the mmg library gathering the mmg2d, mmgs and mmg3d libraries.
