How to parametrize the surface in the scipy/numpy from the points generated in FreeCAD?

[stefankorisnik3]

Given solid object having faces, edges and vertices and so on
How can i parametrize the surface in format (x,y, f(x,y)) for the use in numpy/scipy lib?
How can i parametrize the surface to make mgrid for example?
For the example take the simple Part::Box in the FreeCAD
How can i programmatically read some points and generate map (x,y, f(x,y)) for all x and y?

The goal is to use apply this smoothing on some subsurface:

well, there is (u,v) and (x,y), for (x,y) there is always .Surface.intersect, the (u,v) you will have to figure out on your own.

beginning to think that you have promised someone to do do something but have found yourself to be in over your head...
