【摘要】 截面曲线构造是曲面测量分析、数控加工质量分析等应用中的基本问题之一。针对组合三角Bezier曲面/平面求交交点的分布特点,本文系统研究了组合GC~1截面曲线构造及其数据精减优化二次表示,并将其转化成IGES标准格式输出,为实现两类造型系统(拓扑三角曲面和拓扑矩形曲面)之间的数据交换奠定了良好的基础。更多还原

【Abstract】 Construction of intersection curves is one of the elemental problems in the application of surface measurement analysis and NC machining quality analysis.In according to the distribut- ing characteristics of intersection points between a composite triangular Bezier surface and a plane.This article study the construction of composite GC~1 intersection curves based on the in- tersection points and its data—reduction representation.Finally,the curves was changed into ICES format,which lay a good foundation for data communication between two type modeling systems.更多还原
