Up to there sounds like DELAUNAY3.

"extrude it" is not very specific. It would, though, not be difficult to
replicate the coordinates in any two planes together with incremental
coordinates over a third plane.

With the above it might be pretty trivial -- the extrusion of the delauny hull
might be easy to patch together.

*What* inner surface and *what* outer surface? delauny can only give you an
outer surface; if you want an inner surface then you are talking about shapes
that are not convex and unless you put pretty tight restrictions in, there are
no unique triangulations of non-convex shapes.
