| Abstract: | B-spline surface has been widely used in many projects. It an improved generating algorithm of bi-cubic B-spline curve is discussed. This algorithm can improve generating efficiency greatly. Techniques of establishing orthographic axonometric projection are expounded. An implement method of storing control points using a high performance dynamic array and the software Excel is presented. A software system is developed with Visual C++6.0,through which generating bi-cubic B-spline surface based on control poi... |
