Detailed Description

A surface formed by the iso value. After "Regularised Marching Tetrahedra: improved iso-surface extraction", G.M. Treece, R.W. Prager and A.H. Gee.

Note:

does tets without using cell centres/cell values. Not tested.
regularisation can create duplicate triangles/non-manifold surfaces. Current handling of those is bit ad-hoc for now and not perfect.
regularisation does not do boundary points so as to preserve the boundary perfectly.
uses geometric merge with fraction of bounding box as distance.
triangles can be between two cell centres so constant sampling does not make sense.
on empty patches behaves like zero gradient.
does not do 2D correctly, creates non-flat iso surface.
on processor boundaries might two overlapping (identical) triangles (one from either side)

The handling on coupled patches is a bit complex. All fields (values and coordinates) get rewritten so

empty patches get zerogradient (value) and facecentre (coordinates)
separated processor patch faces get interpolate (value) and facecentre (coordinates). (this is already the default for cyclics)
non-separated processor patch faces keep opposite value and cell centre

Now the triangle generation on non-separated processor patch faces can use the neighbouring value. Any separated processor face or cyclic face gets handled just like any boundary face.
