By now ancient sketch script a single NURBS with 3 dimensional components. It translates the world space coordinates of the component object into the moving-space defined by the ortho-normal vectors of the surface.

Frenet Vectors.
"A Frenet frame is a moving reference frame of n orthonormal vectors which are used to describe a curve locally at each point. It is the main tool in the differential geometric treatment of curves as it is far easier and more natural to describe local properties (e.g. curvature, torsion) in terms of a local reference system than using a global one like the Euclidean coordinates..."
