Any 4 3D points ?

Let's imagine they are disposed as the vertices of tetrahedron
(regular), what would be the right (curved) sheet ?
(I'm questionning the "bend where required" part, which seems obvious
but is really not that obvious at all )

Can we assume that somehow the 4 points are ordered ?

Does the sheet have to be infinite ? (that's what a plane is)
or limited to the 4 points ?

If you have 4 points, can you interpolate some additional ones to use a
bicubic patch ?
