Contouring is created by subtractive carving of a solid. Carving is the traditional hand method. Digital fabrication with a CNC router can achieve much more complex geometry. The direction of carving depends on the router: 3, 4, or 5 axis. Cutting tools can be attached to robotic arms to cut surfaces, as in the ceramic example below. Hand contouring can be done with carving tools, sanders, etc.
Cons: waste of material from routing out the surface.
