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.
