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