68 Cut a tetrahedron mesh by a plane
69 ---------------------------------
71 MeshCut allows to cut a mesh constituted of linear
72 tetrahedrons by a plane. The tetrahedrons intersected
73 by the plane are cut and replaced by elements of
74 various types (tetrahedron, pyramid, pentahedron).
76 MeshCut is a standalone program, reading and
77 producing med files. The cutting plane is defined
78 by a vector normal to the plane and a vertex
79 belonging to the plane.
81 Vertices of a tetrahedron are considered as belonging to
82 the cut plane if their distance to the plane is inferior
83 to L*T where L is the mean edge size of the tetrahedron
