| Abstract: | he paper discusses properties of rational Beta-spline surface and geometric significance of weighing factors, describes structure and function of the modeling system, as well as window-based, object-oriented, event-driven environment. Meanwhile, the algorithms and implementation for rational Beta-splines surface are given and shown by a case. |
