If it were a control mesh instead of a set of control points, then a subdivision surface approach similar to Catmull-Clark: https://en.wikipedia.org/wiki/Catmull%E2%80%93Clark_subdivision_surface could work as a way to make something smooth. Though, for the purposes of matching a surface from control points, an algorithm that fixes vertices is probably preferable to one that fixes face centers.

Looks pretty easy to code in user space to me.
