Differential Geometry of Surfaces, design in two parametric dimensions. Developments in previous chapters, therefore, can all be applied in surface modeling. In curve design, emphasis is laid on the generic (non-analytical) parametric representation of low degree polynomial segments that can be composed together to model a curve.

Design of Curves,Shapes are created by curves in that a surface, such as the rooftop of a car, the fuselage of an aircraft, or a washbasin can be created by motion of curves in space in a specified manner.
