| 摘 要： | 本文采用Bezier和B-Spline函数进行曲线和曲面设计,并将此法用于计算机辅助立体造型.设计过程中,利用曲线局部调节特性,用户可改动特征多边形顶点的位置,以改变曲面的轮廓外形,直到满意为止.在改变观察参数的情况下用户可得到所需的各种透视图和轴测图.

| Abstract: | The Bezier and B-Spline functions are taken for designing curves and surfaces in this paper. This method is takenfor designing modelling solids by computer-aided. Using the localcontrol nature of the curve shape, the user can move the vertexof characteristic polygon to modify the surface shape he needs.Changing viewing parameters, the user will obtain various pers-pective and parallel projectiv views as required. |
