74 Cut a tetrahedron mesh by a plane
75 ---------------------------------
77 MeshCut allows to cut a mesh constituted of linear
78 tetrahedrons by a plane. The tetrahedrons intersected
79 by the plane are cut and replaced by elements of
80 various types (tetrahedron, pyramid, pentahedron).
82 MeshCut is a standalone program, reading and
83 producing med files. The cutting plane is defined
84 by a vector normal to the plane and a vertex
85 belonging to the plane.
87 Vertices of a tetrahedron are considered as belonging to
88 the cut plane if their distance to the plane is inferior
89 to L*T where L is the mean edge size of the tetrahedron
