| 摘 要： | 以标准文件IGES创建的多裁剪曲面模型为研究对象,以图论为研究工具,建立了曲面的拓扑信息,并根据多裁剪曲面模型中孔洞的起源和相对尺寸大小,提出了不同的自动填充策略.特别对产生于多个裁剪曲面之间的内孔,采用了插值于边界跨界切矢曲线的双三次混合Coons曲面进行填充,使填充曲面与周边型面达到一阶几何连续,为最终的设计模型提供了良好性质的几何型面.实验表明整个算法稳定可靠,适应性强,并具有良好的通用性.

| Abstract: | Multiple trimmed free surfaces mode created from IGES standard file is studied.Using graph theory,topological information of the surfaces is established.According to different source and size of holes,different methods of filling holes in multiple trimmed free surfaces mode are suggested.Especially,the using of Coons method makes that filled surface and peripheral surfaces between multiple trimmed free surfaces keep the first rank continuity.The filled multiple trimmed free surfaces mode provides satisfacto... |
