摘  要:
The principle and method of computer-aided modelling design using the cubic spline curve,Bezier curve,B-spline curve and Bezier-B-spline surface are expounded.A new system with Chinese character used for modelling free-form curves and curve surfaces in in- teractive design is presented.The random modification,deletion,the insertion of vertices in- formation,the graphic transformation and windowing/clipping can readily be done in this system.The system gives a useful means for computer-aided modelling and computer-aided teaching.
