计算机辅助曲面造型设计的探讨与实践

在计算机上进行三维几何设计时，常会遇到大量的曲面造型问题，诸如汽车车身设计、飞机外形设计等等。因此，在计算机辅助几何设计领域中关于曲面造型的研究一直是国内外十分关注的问题。在曲面造型的实际过程中，Ｂｅｚｉｅｒ曲线曲面、Ｂ样条曲线曲面和Ｈｅｒｍｉｔ曲线曲面都是非常有用的曲面造型工具，合理地运用它们可以高效率、高质量地实现各种不同形状的曲面都是非常有用的曲面造型工具，合理地运用它们可以高效率、高质量地

Research and Practice of Computer Aided Curved Surface Design

Problems concerning curved surface modelling arise when using computers for three - dimensional geometric design, e. g. the design of car bodies and the configuration of planes. Therefore, Curved surface modelling is one of the most important research topics in Computer Aided Geometric Design (CADG). Three types of splines and patchs: Bezier, B - spline and Hermit, are all useful tools for modelling curved surface.Making proper use of these curves and surfaces best generate various of curved surface rnodelling design. Based on working practice, some skills and experience about curved surface modelling will be discussed in this paper.
