[Insight-users] [vtkusers] hexagonal mesh?

[Alexandre GOUAILLARD]

Just a note,

a simplex mesh is NOT an hexagonal mesh. Only if the original mesh is
regular, has no border and has the correct genus, have all the points
6 edges, in which case the dual simplex mesh is hexagonal. In all the
other case, you will have some cells with 5, 7 or an arbitrary number
of faces.
